The Canadian Paediatric Society recommends vision screening by your child’s primary health-care provider at all infant and well-child visits. If there are any risk factors (for example prematurity, certain genetic syndromes) or vision complaints, they should be seen by a licensed eye care professional. Keep in mind that the sooner a condition is discovered, the sooner treatment can be started.</p> <figure><img alt="An optometrist’s office" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-office_EN.jpg" /> </figure> <h3>Signs that your child needs to see a licensed eye care professional</h3><p>There are a number of signs that parents should look for that may indicate their child is having a visual problem. Here are a few examples.</p> <figure><img alt="An optometrist holds up a lens" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-lens_EN.jpg" /> </figure> <ul><li>If, when you look at your child, you notice that one eye is not aligned.</li><li>Your child has trouble focusing or squints a lot.</li><li>Your child holds books too close or loses their place when reading.</li><li>Your child turns or tilts their head when they want to look at something.</li><li>Your child covers an eye when stepping into sunlight.</li><li>One of your child's eyes is whiter and brighter than the other eye in a picture taken head on.</li><li>Your child moves to the front of the classroom to see the blackboard better.</li></ul><p>Your child may not complain about not seeing correctly because they are unaware there is a problem. Only you, as a parent, can make sure that any visual problem your child may have is caught early on.</p><h2>Eye examinations for children aged two and over</h2><p>A licensed eye care professional often uses toys to get a child’s attention or may involve the parents. It also helps if one of the parents has an eye examination while the child watches. To lessen your child’s anxiety, explain what is going to happen in a simple way they can understand.</p> <figure><img alt="An optometrist uses a toy to get a child’s attention" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-toys_EN.jpg" /> </figure> <h3>What tests are performed during an eye examination?</h3><p>A licensed eye care professional will first review your child’s history and will ask about any health issues or conditions that may affect your child’s eye health. The will then ask parents questions such as:</p><ul><li>Have you noticed any visual problems, such as squinting, tilting/turning their head or holding books too close?</li><li>Was your baby premature? Did anything happen during the birth of your baby? Was it a difficult delivery? Was the baby hurt during the delivery?</li><li>What is your child's development like?</li><li>Is there any history of eye turn or <a href="/Article?contentid=835&language=English">lazy eye</a> in the family?</li></ul><p>Remember to bring to your appointment any documents that can help you answer these types of questions. Your child will then have a series of tests to check their vision. None of them are uncomfortable, painful, invasive or risky. They include (but are not limited to) the following tests.</p><div class="akh-series"><div class="row"><div class="col-md-12"> <figure> <img src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-vis-acuity_EN.jpg" alt="An optometrists chart for a young child" /> </figure> <h3>Visual acuity</h3><p> <a href="/Article?contentid=1941&language=English">Visual acuity</a> is how clearly and sharply your child can see objects that are far away and close up. Your child will cover one eye and read the letters or pictures projected on a wall or on a chart. They will then cover the other eye and do the same. This tests vision at a distance.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist’s chart for measuring near sight" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-reading_EN.jpg" /> </figure> <p>To test your child’s near vision, your child will be asked to read lines of text or pictures that become smaller and smaller on a hand-held chart.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist checks a patients binocular vision" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-binocular_EN.jpg" /> </figure> <h3>Binocular vision</h3><p>Binocular vision is seeing with both eyes. The licensed eye care professional makes sure that, up close and at a distance, the eyes are aligned and there is no eye turn.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="Light-testing pupil movement" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-light_EN.jpg" /> </figure> <h3>Pupil response</h3><p>Pupil response is tested with a moving light in front of the eyes. The pupils (the black circle in the centre of the iris) should get smaller when they are exposed to light and get larger when the light is removed.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="Testing for colour-blindness" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-colour_EN.jpg" /> </figure> <h3>Colour blindness</h3><p>Colour blindness is the inability to distinguish between colours in normal light conditions. Colour blindness can be as extreme as seeing only in black and white (very uncommon) or it could just mean being unable to distinguish different shades of colours (for example different reds). To test colour vision, your child will look at a chart with drawings, letters or numbers represented only with colours.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist measures eye turn" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-eyeturn_EN.jpg" /></figure> <h3>Eye turn and extraocular motility</h3><p>Eye turn (or <a href="/Article?contentid=836&language=English">strabismus</a>) is when the eyes are not aligned. The eyes can be turning in ("crossed") or turning out ("wall eye") or one can be higher than the other. A prism bar measures the angle of an eye turn.</p><p>Extraocular motility is your child's ability to move their eyes in different directions.</p></div></div><h3>Eye convergence</h3><p>Eye convergence (or eye crossing) is the inward movement of both eyes toward each other. The licensed eye care professional holds a stick in front of your child and asks them to follow it with their eyes. By moving the stick closer to your child’s face, your child’s eyes move inward toward each other to maintain focus on the stick. This is an important skill that is required for reading. When reading, the eyes converge for a long periods of time. Reading for 20 minutes is going to be uncomfortable for your child if their eyes do not move towards each other properly. As a result, your child may avoid reading.</p><div class="akh-series"><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist assessing prescription lenses" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-retinoscopy_EN.jpg" /> </figure> <h3>Retinoscopy</h3><p>Retinoscopy is a light test to see if your child needs corrective glasses (or prescription lenses). With an adult, the licensed eye care professional tests different lenses and asks the patient whether they can see well. It is difficult for a child, as they cannot understand what “seeing better or worse” means.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="The optometrist places eye drops to dilate the pupils" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-drops_EN.jpg" /> </figure> <h3>Focusing ability</h3><p>To test focusing ability, the licensed eye care professional may put two drops of a drug in each eye to dilate the pupil. This prevents accommodation, the ability to see an object clearly at different distances. The eye drops mean that your child cannot see up close clearly. Putting the drops in does not hurt and their effect will wear off in a few hours. It may take six to eight hours to recover the focusing ability. Pupils can stay dilated for up to 24 hours.</p></div></div> <div class="row"><div class="col-md-12"> <figure><img alt="Dilated fundus examination" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-dfe_EN.jpg" /> </figure> <h3>Dilated fundus</h3><p>Dilated fundus examination checks the retinaat the rear of the eye and makes sure it is healthy. Your child places their chin on the device and rests their forehead against it. The device is moved around your child’s head to allow the licensed eye care professional to see the entire retina.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist looks into a patient’s eye" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-ret-test_EN.jpg" /> </figure> <p>If your child is uncomfortable around such an intimidating device, the licensed eye care professional may use a smaller device instead.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist wearing special glasses for an examination" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-op-glasses_EN.jpg" /> </figure> <h3>General eye health</h3><p>The licensed eye care professional looks at the cornea, lens and blood vessels to make sure that each part of your child’s eye is healthy. They use different objects such as a portable lens and even wears special glasses to perform this check.</p></div></div></div></div><h2>How to choose glasses for your child<br></h2><p>Ask your optician to help you find glasses that will fit your child properly. Involve your child in the process if they are old enough to understand. Remember, they are your child’s glasses not yours. If your child does not like the glasses, they are not going to wear them. Instead your child may hide or break the glasses or do whatever they can to not wear them.</p> <figure> <img alt="Choosing a pair of glasses" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-glasses_EN.jpg" /> </figure><h2>Help your child prepare for their eye examination</h2><p>To help you be ready for your child's visit to the licensed eye care professional, you and your child can watch this video together.</p> <div class="asset-video"> <iframe src="https://www.youtube.com/embed/-VassqhXmQw?rel=0" frameborder="0"></iframe> </div> <br><h2>References</h2> <p>Canadian Ophthalmological Society. <em><a href="http://www.cos-sco.ca/vision-health-information/your-ophthalmologist/">Your Ophthalmologist & The Vision Care Team</a>. </em>Retrieved May 23, 2014. <br></p> Canadian Paediatric Society. <a href="http://www.cps.ca/documents/position/children-vision-screening" target="_blank"><em>Vision screening in infants, children and youth</em></a> (2014, February 1)<br> <p>Retrieved May 23, 2014. <br></p>
Examen ophtalmologique pour votre enfantEExamen ophtalmologique pour votre enfantEye examination for your childFrenchOphthalmologyChild (0-12 years);Teen (13-18 years)EyesNervous systemNon-drug treatmentCaregivers Adult (19+)NA2014-05-22T04:00:00ZAgnes Wong, MD, PhD, FRCSC;Maryam Rezvani, OD;Helen Siomos, ROHealth (A-Z) - ProcedureHealth A-Z<p>Découvrez ce que sont les examens ophtalmologiques, le rôle de l’optométriste et l’équipement utilisé, afin que vous puissiez préparer votre enfant, et vous-même, à un examen de la vision.</p><h2>Qu’est-ce qu’un examen ophtalmologique?</h2> <p>Un examen ophtalmologique consiste en une série de tests réalisés par un professionnel des soins oculaires autorisé (par exemple, un ophtalmologue ou un optométriste) afin de vérifier la santé des yeux de votre enfant. </p><h2>À retenir</h2> <ul><li>Un examen oculaire est réalisé par un professionnel des soins oculaires agréé, soit un ophtalmologue ou un optométriste, qui vérifie la santé oculaire et la vision de votre enfant. </li><li>Si vous suspectez que votre enfant est atteint d’un problème de vision, demandez l’avis d’un professionnel des soins oculaires agréé. </li><li>Lorsque vous choisissez des lunettes de votre enfant, assurez-vous qu’il les aime et il les portera.</li></ul><h2>Examens oculaires</h2><p>Les ophtalmologues et les optométristes sont des professionnels qui sont autorisés à réaliser des examens oculaires. La Société canadienne de pédiatrie recommande que votre enfant subisse un dépistage visuel par son fournisseur de soins de santé primaires à chacune des consultations médicales courantes pour les nourrissons et les enfants. Si certains facteurs de risques sont présents (par exemple, de la prématurité, certains syndromes génétiques), ils devraient être examinés par un professionnel agréé dans les soins oculaires. N’oubliez pas que le plus tôt un problème est découvert, le plus tôt un traitement peut être entrepris.</p> <figure><img alt="An optometrist’s office" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-office_EN.jpg" /> </figure> <h3>Symptômes laissant croire que votre enfant a besoin de consulter un professionnel des soins oculaires agréé</h3><p>Les parents devraient surveiller certains symptômes qui peuvent indiquer que leur enfant présente un problème visuel. Voici quelques exemples :</p> <figure> <img alt="An optometrist holds up a lens" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-lens_EN.jpg" /> </figure> <ul><li>si vous observez que l’un des yeux n’est pas aligné lorsque vous regardez votre enfant; </li><li>votre enfant éprouve de la difficulté à faire le focus ou il louche beaucoup; </li><li>votre enfant tient ses livres trop près de ses yeux ou perd l’endroit où il est rendu lorsqu’il lit; </li><li>votre enfant tourne ou penche sa tête lorsqu’il veut regarder quelque chose; </li><li>votre enfant cache un œil lorsqu’il sort au soleil; </li><li>l’un des yeux de votre enfant est plus blanc et plus brillant que l’autre sur des photographies prises de face; </li><li>votre enfant s’assoit à l’avant de la classe afin de mieux voir au tableau. </li></ul><p>Votre enfant pourrait ne pas se plaindre de mal voir, car il peut ne pas être conscient du problème. Vous seul, en tant que parent, pouvez vous assurer de détecter de manière précoce tout problème oculaire pouvant être présent chez votre enfant.</p><h2>Examens oculaires pour les enfants âgés de plus de deux ans</h2><p>Un professionnel des soins oculaires agréé utilise souvent des jouets afin d’attirer l’attention d’un enfant ou il peut demander la participation des parents. Si l’un des parents subit aussi un examen des yeux pendant que l’enfant regarde, cela aide. Afin de diminuer l’anxiété de votre enfant, expliquez-lui ce qui va se passer en des mots simples qu’il pourra comprendre.</p><h3>Quels tests sont réalisés au cours d’un examen oculaire?</h3><p>Un professionnel des soins oculaires agréé étudiera tout d’abord les antécédents de votre enfant et posera des questions à propos de problèmes ou de troubles de santé qui pourraient toucher la santé des yeux de votre enfant. Il posera ensuite des questions aux parents telles que :</p><ul><li>avez-vous observé des problèmes visuels, comme loucher, pencher ou tourner la tête ou tenir un livre trop près des yeux? </li><li>votre bébé était-il prématuré? Est-ce qu’un incident s’est produit pendant l’accouchement de votre bébé? Est-ce que ce fut un accouchement difficile? Est-ce que le bébé a été blessé au cours de l’accouchement? </li><li>Comment s’est déroulé le développement de votre enfant? </li><li>Existe-t-il des antécédents d’yeux croisés ou d’<a href="/Article?contentid=835&language=French">œil paresseux</a> dans la famille? </li></ul><p>N’oubliez pas d’apporter à votre rendez-vous tous les documents qui peuvent vous aider à répondre à ce type de questions. Votre enfant passera ensuite une série d’examens afin de vérifier leur vision. Aucun d’entre eux n’est inconfortable, douloureux, invasif ou risqué. Ils comprennent (sans y être limités) les examens suivants.</p><div class="akh-series"><div class="row"><div class="col-md-12"> <figure> <img src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-vis-acuity_EN.jpg" alt="An optometrists chart for a young child" /> </figure> <h3>Acuité visuelle</h3><p>L’<a href="/Article?contentid=1941&language=French">acuité visuelle</a> représente à quel point votre enfant peut distinguer clairement et avec précision des objets qui sont éloignés ou très près. Votre enfant couvrira l’un de ses yeux et lira les lettres ou les images projetées sur un mur ou un graphique. Il couvrira ensuite l’autre œil et reprendra la procédure. Ceci évalue la vision à une certaine distance.</p></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist’s chart for measuring near sight" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-reading_EN.jpg" /> </figure> <p>Afin d’examiner la vision de près de votre enfant, on demandera à celui-ci de lire des lignes de texte ou d’images qui deviennent de plus en plus petites sur un tableau tenu à la main.</p></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist checks a patients binocular vision" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-binocular_EN.jpg" /> </figure> <h3>Vision binoculaire</h3><p>La vision binoculaire permet de voir avec les deux yeux. Un professionnel des soins oculaires agréé s’assure qu’avec une vision de près et de loin, les yeux sont alignés et qu’il n’y a pas présence d’yeux croisés.</p></div><div class="row"><div class="col-md-12"> <figure><img alt="Light-testing pupil movement" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-light_EN.jpg" /> </figure> <h3>Réaction de la pupille</h3><p>La réaction de la pupille est évaluée à l’aide du déplacement d’une source lumineuse devant les yeux. Les pupilles (le cercle noir présent au centre de l’iris) devraient être plus petites lorsqu’elles sont exposées à la lumière et devenir plus grandes lorsque la source lumineuse est enlevée.</p></div><div class="row"><div class="col-md-12"> <figure><img alt="Testing for colour-blindness" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-colour_EN.jpg" /> </figure> <h3>Daltonisme</h3><p>Le daltonisme est l’incapacité de distinguer certaines couleurs sous des conditions d’éclairage normales. Le daltonisme peut être aussi extrême que de voir uniquement en noir et blanc (très peu fréquent) ou il peut simplement dire d’être incapable de distinguer entre différents tons d’une même couleur (par exemple, différentes sortes de rouge). Afin d’évaluer la vision en couleur, votre enfant regardera un graphique avec des dessins, des lettres et des nombres représentés uniquement par des couleurs.</p></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist measures eye turn" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-eyeturn_EN.jpg" /></figure> <h3>Yeux croisés et motilité extraoculaire</h3><p>Un œil croisé (ou <a href="/Article?contentid=836&language=French">strabisme</a>) se produit lorsque les yeux ne sont pas alignés. Les yeux peuvent être tournés vers l’intérieur (croisés) ou vers l’extérieur (strabisme divergent) ou bien l’un peut être plus élevé que l’autre. Une barre de prisme mesure l’angle d’un œil croisé. </p><p>La motilité extraoculaire représente la capacité de votre enfant à déplacer ses yeux dans différentes directions.</p></div><h3>Convergence des yeux</h3><p>La convergence des yeux (ou croisement des yeux) est un mouvement vers l’intérieur des deux yeux en direction l’un de l’autre. Le professionnel des soins oculaires agréé tient un bâton devant votre enfant et lui demande de le suivre avec ses yeux. En déplaçant le bâton près du visage de votre enfant, les yeux de ce dernier se déplacent à l’intérieur l’un vers l’autre afin de maintenir le bâton au foyer. Il s’agit d’une habileté importante qui est requise pour la lecture. Lorsqu’on lit, les yeux convergent pour de longues périodes de temps. Lire pendant 20 minutes deviendra inconfortable pour votre enfant si ses yeux ne se déplacent pas l’un vers l’autre de façon adéquate. Pour cette raison, votre enfant pourrait éviter la lecture.</p><div class="akh-series"><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist assessing prescription lenses" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-retinoscopy_EN.jpg" /> </figure> <h3>Réti​noscopie</h3><p>La rétinoscopie est un examen avec source lumineuse permettant de voir si votre enfant a besoin de lunettes correctrices (ou verres de prescription). Avec une personne adulte, le professionnel des soins oculaires agréé essaie différentes lentilles et demande au patient s’il voit bien. C’est plus difficile avec un enfant, car il ne peut comprendre ce que « voir mieux ou moins bien » signifie.</p></div><div class="row"><div class="col-md-12"> <figure><img alt="The optometrist places eye drops to dilate the pupils" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-drops_EN.jpg" /> </figure> <h3>Capacité de focalisation</h3><p>Afin d’évaluer la capacité de focalisation, le professionnel des soins oculaires agréé pourrait déposer deux gouttes d’un médicament dans chaque œil pour dilater la pupille. Ceci prévient l’adaptation, la capacité à voir clairement un objet à différentes distances. Les gouttes oculaires font que votre enfant ne peut pas voir clairement de près. Mettre les gouttes n’est pas douloureux et leur effet s’effacera dans quelques heures. Six à huit heures peuvent s’écouler avant de recouvrer la capacité de focalisation. Les pupilles peuvent demeurer dilatées jusqu’à 24 heures.</p></div><div class="row"><div class="col-md-12"> <figure><img alt="Dilated fundus examination" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-dfe_EN.jpg" /> </figure> <h3>Fonds d’œil</h3><p>L’examen du fond d’œil observe la rétine dans le fond de l’œil et s’assure qu’elle est saine. Votre enfant place son menton sur l’appareil et y pose son front. L’appareil se déplace autour de la tête de votre enfant et permet au professionnel des soins oculaires agréé de voir l’ensemble de la rétine.<br></p></div> </div></div></div></div></div></div></div></div></div></div></div><h2>Comment choisir les lunettes de votre enfant?</h2><p>Demandez à votre opticien de vous aider à trouver des lunettes qui conviennent à votre enfant. Faites participer votre enfant au processus s’il est assez grand pour comprendre. N’oubliez pas, ce sont les lunettes de votre enfant, pas les vôtres. Si votre enfant n’aime pas ses lunettes, il ne les portera pas. À la place, votre enfant pourrait cacher ses lunettes, les briser ou faire tout ce qu’il peut afin de ne pas les porter.</p> <figure> <img alt="Choosing a pair of glasses" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-glasses_EN.jpg" /> </figure> <h2>Aider votre enfant à se préparer à son examen</h2><p>Afin de vous aider à vous préparer au rendez-vous de votre enfant chez le professionnel des soins oculaires agréé, vous et votre enfant pouvez regarder cette vidéo ensemble.</p><div class="asset-video"> <iframe src="https://www.youtube.com/embed/-VassqhXmQw?rel=0" frameborder="0"></iframe> </div>

They are licensed medical specialists in eye and vision care, surgery and medical interventions, and in diagnosing, treating and preventing serious eye disease. Ophthalmologists perform comprehensive eye exams, conduct surgery, prescribe and give medication and determine the ideal prescription for corrective lenses.</p> <p>Ophthalmologists are physicians who, when they graduate from medical school, do several years of post-graduate training in diagnosing and treating diseases of the eye.</p> <h3>Optometrists</h3> <p>Optometrists are primary health-care providers who specialize in examining, diagnosing, treating, managing and preventing disease and disorders of the visual system and the eye and associated structures. They also diagnose ocular manifestations of systemic conditions.</p> <p>A four-year doctor of optometry degree program follows a university degree.</p> <h3>Opticians</h3> <p>Registered opticians are specially trained to design, fit and dispense eyeglasses, contact lenses, low vision aids and prosthetic ocular devices. They interpret written prescriptions from ophthalmologists (medical doctors) and optometrists (non-medical eye care professionals) to determine the specifications of ophthalmic appliances necessary to correct a person’s eyesight.</p><h2>Key points</h2> <ul> <li>An eye examination is performed by a licensed eye care professional, either an ophthalmologist or optometrist, who checks your child’s eye health and vision.</li> <li>If you suspect your child has a vision problem, ask a licensed eye care professional’s opinion.</li> <li>When choosing glasses for your child, make sure they like their glasses and they are going to wear them.</li> </ul><h2>Eye examinations</h2><p>Ophthalmologists and optometrists are both professionals that are licensed to perform eye examinations.

They include (but are not limited to) the following tests.</p><div class="akh-series"><div class="row"><div class="col-md-12"> <figure> <img src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-vis-acuity_EN.jpg" alt="An optometrists chart for a young child" /> </figure> <h3>Visual acuity</h3><p> <a href="/Article?contentid=1941&language=English">Visual acuity</a> is how clearly and sharply your child can see objects that are far away and close up. Your child will cover one eye and read the letters or pictures projected on a wall or on a chart. They will then cover the other eye and do the same. This tests vision at a distance.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist’s chart for measuring near sight" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-reading_EN.jpg" /> </figure> <p>To test your child’s near vision, your child will be asked to read lines of text or pictures that become smaller and smaller on a hand-held chart.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist checks a patients binocular vision" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-binocular_EN.jpg" /> </figure> <h3>Binocular vision</h3><p>Binocular vision is seeing with both eyes. The licensed eye care professional makes sure that, up close and at a distance, the eyes are aligned and there is no eye turn.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="Light-testing pupil movement" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-light_EN.jpg" /> </figure> <h3>Pupil response</h3><p>Pupil response is tested with a moving light in front of the eyes. The pupils (the black circle in the centre of the iris) should get smaller when they are exposed to light and get larger when the light is removed.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="Testing for colour-blindness" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-colour_EN.jpg" /> </figure> <h3>Colour blindness</h3><p>Colour blindness is the inability to distinguish between colours in normal light conditions. Colour blindness can be as extreme as seeing only in black and white (very uncommon) or it could just mean being unable to distinguish different shades of colours (for example different reds). To test colour vision, your child will look at a chart with drawings, letters or numbers represented only with colours.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist measures eye turn" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-eyeturn_EN.jpg" /></figure> <h3>Eye turn and extraocular motility</h3><p>Eye turn (or <a href="/Article?contentid=836&language=English">strabismus</a>) is when the eyes are not aligned. The eyes can be turning in ("crossed") or turning out ("wall eye") or one can be higher than the other. A prism bar measures the angle of an eye turn.</p><p>Extraocular motility is your child's ability to move their eyes in different directions.</p></div></div><h3>Eye convergence</h3><p>Eye convergence (or eye crossing) is the inward movement of both eyes toward each other. The licensed eye care professional holds a stick in front of your child and asks them to follow it with their eyes. By moving the stick closer to your child’s face, your child’s eyes move inward toward each other to maintain focus on the stick. This is an important skill that is required for reading. When reading, the eyes converge for a long periods of time. Reading for 20 minutes is going to be uncomfortable for your child if their eyes do not move towards each other properly. As a result, your child may avoid reading.</p><div class="akh-series"><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist assessing prescription lenses" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-retinoscopy_EN.jpg" /> </figure> <h3>Retinoscopy</h3><p>Retinoscopy is a light test to see if your child needs corrective glasses (or prescription lenses). With an adult, the licensed eye care professional tests different lenses and asks the patient whether they can see well. It is difficult for a child, as they cannot understand what “seeing better or worse” means.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="The optometrist places eye drops to dilate the pupils" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-drops_EN.jpg" /> </figure> <h3>Focusing ability</h3><p>To test focusing ability, the licensed eye care professional may put two drops of a drug in each eye to dilate the pupil. This prevents accommodation, the ability to see an object clearly at different distances. The eye drops mean that your child cannot see up close clearly. Putting the drops in does not hurt and their effect will wear off in a few hours. It may take six to eight hours to recover the focusing ability. Pupils can stay dilated for up to 24 hours.</p></div></div> <div class="row"><div class="col-md-12"> <figure><img alt="Dilated fundus examination" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-dfe_EN.jpg" /> </figure> <h3>Dilated fundus</h3><p>Dilated fundus examination checks the retinaat the rear of the eye and makes sure it is healthy. Your child places their chin on the device and rests their forehead against it. The device is moved around your child’s head to allow the licensed eye care professional to see the entire retina.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist looks into a patient’s eye" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-ret-test_EN.jpg" /> </figure> <p>If your child is uncomfortable around such an intimidating device, the licensed eye care professional may use a smaller device instead.</p></div></div><div class="row"><div class="col-md-12"> <figure><img alt="An optometrist wearing special glasses for an examination" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-op-glasses_EN.jpg" /> </figure> <h3>General eye health</h3><p>The licensed eye care professional looks at the cornea, lens and blood vessels to make sure that each part of your child’s eye is healthy. They use different objects such as a portable lens and even wears special glasses to perform this check.</p></div></div></div></div><h2>Eye examinations for children aged under two </h2> <p>Different tests are used to check an infant’s visual acuity. These tests are used to assess your child’s eye and vision development.</p> <p> “Preferential looking” tests for vision problems in children aged under two. For example, a licensed eye care professional may use a board with a small hole in the middle to look at the child without the child seeing them and being distracted. The board has two halves: one is a grey square, the other has black and white stripes. The licensed eye care professional will want to check if the child looks at the stripes, as this is what babies will normally choose to do. </p> <p>The infants's visual acuity is tested as the stripes become smaller and closer together and look more like the grey side. </p> <p>If a problem is suspected, further tests will be carried out, and your child might be given prescription lenses or referred to a paediatric ophthalmologist. A paediatric ophthalmologist is a doctor specialized in eye conditions in children.</p> <p>Remember that, when children are born, they do not have <a href="/Article?contentid=1941&language=English">perfect vision (20/20)</a>. It takes some time to get there.</p> <p>When booking an appointment, make sure to tell the licensed eye care professional your child’s age so they can prepare the appropriate tests and material.</p><h2>How to choose glasses for your child<br></h2><p>Ask your optician to help you find glasses that will fit your child properly. Involve your child in the process if they are old enough to understand. Remember, they are your child’s glasses not yours. If your child does not like the glasses, they are not going to wear them. Instead your child may hide or break the glasses or do whatever they can to not wear them.</p> <figure> <img alt="Choosing a pair of glasses" src="https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-glasses_EN.jpg" /> </figure><h2>Help your child prepare for their eye examination</h2><p>To help you be ready for your child's visit to the licensed eye care professional, you and your child can watch this video together.</p> <div class="asset-video"> <iframe src="https://www.youtube.com/embed/-VassqhXmQw?rel=0" frameborder="0"></iframe> </div> <br><h2>References</h2> <p>Canadian Ophthalmological Society. <em><a href="http://www.cos-sco.ca/vision-health-information/your-ophthalmologist/">Your Ophthalmologist & The Vision Care Team</a>. </em>Retrieved May 23, 2014. <br></p> Canadian Paediatric Society. <a href="http://www.cps.ca/documents/position/children-vision-screening" target="_blank"><em>Vision screening in infants, children and youth</em></a> (2014, February 1)<br> <p>Retrieved May 23, 2014. <br></p>https://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkup-girl_EN.jpghttps://assets.aboutkidshealth.ca/akhassets/PMD_eye-checkuph-lens_EN.jpgEye examination for your childFalse
