Strabismus - Definition


Strabismus is an eye condition, also called heterotropia, which is caused by an impaired convergence, causing the eyes to point in two different directions, in other words: a squint. One of the received vision fields is generally erased by the brain in order to maintain clear vision, a process which is called neutralization. Strabismus is common in babies under 4 months of age, and can resolve itself in most cases if intermittent. However, sometimes it persists, and additional investigation is needed. A strabismus can be qualified as convergent (or esotropia) when one eye is turned inwards, or divergent (or exotropia) when one is turned outwards. Rarer forms consist of a vertical divergence. Different tests are performed in these cases by an ophthalmologist. For children, treatment consists of glasses, with surgery an option if the condition persists.
