Sixty percent of children identified as problem learners actually suffer from undetected vision problems, according to a 2009 study by the American Optometric Association (AOA). Undetected and untreated eye disorders, such as amblyopia and strabismus, can result in delayed reading and poorer outcomes in school.

Studies indicate that visual factors are better predictors of academic success than race or socioeconomic status. However, one in four school-age children suffers from vision problems that could have been treated if the child had been properly examined.

Unfortunately most kids do not receive a comprehensive eye exam before they enter school. Many with vision disorders fall through the cracks of “pediatrician vision screenings” and assume an “eye exam” has been performed. Yet in fact, a comprehensive eye exam by an optometrist measures more than just visual acuity at distance. Optometrists not only measure vision at distance and near, but measure the child’s processing of letters numbers, movements of objects, and the abilitly to use the eyes together (a necessity for the 3D age we are in). In addition, the health of the eyes, a window into the internal health of a child is checked thoroughly with the retinal exam.

Children who are successfully treated for their eye problems show increased performance in school. Studies find that the provision of eye glasses and vision therapy to children is correlated with improved grades and higher scores on standardized tests.

The American Optometrist Association (AOA) based on science and studies, recommends that infants should have their first comprehensive eye exam at 6 months of age. This exam is a specialized exam that the optometrist can look for any abnormalities and risk factors with the parents. Children then should have additional eye exams at age 3, and just before they enter the first grade – at about age 5 or 6.

For school-aged children, the AOA recommends an eye exam every two years if no vision correction is required. Children who need eyeglasses or contact lenses should be examined annually or as recommended by their optometrist.

Eyelid twitching (myokymia) is a spontaneous contraction of the upper or lower eyelids. Patients usually come in at first annoyed as well as slightly concerned of its presentation. A normal examination will include a full medical and social history of the patient. Then proper external examination of the eyes including several diagnostic testing for irritants, infections, allergies, and dry eye signs will be looked it.

The underlying cause eyelid myokymia is not very well understood. The event is most likely nerve fibers within the eyelid muscle caught in a spasm.  Possible precipitating factors include stress, anxiety, fatigue, and excessive caffeine or alcohol intake. Dry eye syndrome (linked to several risk factors) and contact lens side effects are also a possible cause. Fortunately some of these factors can be dealt with and treated with your eye doctor, and possibly calming the eyelid twitching.

Lid myokymia most often is benign and self-limiting. It is important to have a it looked at by a competent eye doctor. If you are in the Los Angeles area, Dr. Fouad Melamed is a licensed optometrist and accepts your medical health insurance with your regular office copay to have a full look at your eyelid twitching.
