Other types of amblyopia (such as from high refractive error) might cause a child to move very close to objects or squint his or her eyes. Some forms of amblyopia, such as that associated with large-deviation strabismus, may be easily detected by parents. How can I get early treatment for amblyopia? Better treatment success is achieved when treatment starts early, however. How old is too old for amblyopia treatment?Ī recent National Institutes of Health (NIH) study confirmed that some improvement in vision can be attained with amblyopia therapy initiated in younger teenagers (through age 14 years). Children with cataracts or other “amblyogenic” conditions are usually treated promptly in order to minimize the development of amblyopia. If necessary, children with refractive errors (nearsightedness, farsightedness or astigmatism) can wear glasses or contact lenses when they are as young as one week old. When should amblyopia be treated?Įarly treatment is always best. If asymmetric amblyopia (one eye better than the other) occurs, then patching or eye drops may be added. What can be done if my child has equal high amounts of farsightedness and/or astigmatism and is diagnosed with bilateral amblyopia?īilateral amblyopia is usually treated with consistent, early glasses, and/or contact lenses with follow-up over a long period of time. Penalizing the better seeing eye forces the brain to pay attention to the image coming from the weaker eye, prompting the brain to learn to see better from the weaker eye. For many children, the amblyopia or poor vision may also be treated by penalizing the better seeing eye by patching it or using blurring eye drops (atropine). Glasses may be effective in treating some types of refractive amblyopia and strabismic amblyopia (such as accommodative esotropia). Will glasses help a child with amblyopia to see better? This kind of amblyopia can affect one or both eyes and can be best helped if the problem is found early. For these reasons, this kind of amblyopia in children may not be found until the child has a vision test. Therefore, parents and pediatricians may not realize there is a problem. In addition, the amblyopic eye may not look any different from the better seeing eye. The vision problem may not be detected because the child does not complain of blurry vision. The child may see well from one eye that has less of a glasses need compared to the other eye. The brain does not learn how to see well from an eye that has a great need for glasses. Refractive amblyopia happens when there is a large or unequal amount of refractive error (glasses strength) between a child's eyes. Sometimes this kind of amblyopia can affect both eyes. If not treated very early, these children never learn to see very well and can have very poor vision. What is deprivation amblyopia?ĭeprivation amblyopia develops when cataracts or similar conditions “deprive” young children’s eyes of visual experience. When this happens, the brain begins to ignore, or “turns off” the eye that is not straight and the vision subsequently drops in that eye. Strabismic amblyopia develops when the eyes are not straight. The three types of amblyopia, strabismic amblyopia, refractive amblyopia, and deprivation amblyopia, may occur at the same time in a single eye. Rarely there is a structural anomaly that impairs vision like a droopy eyelid or an opacity in the eye, such as a cataract or corneal scar. Another common cause is strabismus or eye misalignment. The most common cause is refractive error in one or both eyes that is not corrected early in childhood resulting in poor development of the visual function in the affected eye(s). Amblyopia may occur despite normal appearance of the eye structures. If children are not able to use their eyes, the vision centers in the brain do not develop properly and the vision is decreased. As infants grow and use their eyes, the vision improves as the vision centers in the brain develop. Normal vision develops during the first few years of life. 1: Amblyopia occurs in childhood when an eye gives a blurry or otherwise poor image to the brain that impairs the brain’s ability to learn to see. Another word for amblyopia is often “ lazy eye.” It is the leading cause of vision loss amongst children ].įig. In amblyopia, there may not be an obvious problem of the eye. Vision loss occurs in this case because nerve pathways between the brain and the eye are not properly stimulated. In amblyopia, the brain receives a poor image from the eye and thus does not “learn to see well. In the first few years of life, the brain must learn to see or interpret the images provided by the eyes. von Noorden Young Investigator AwardĪmblyopia is decreased vision in one or both eyes due to abnormal vision development in infancy or childhood.
