What Is Strabismus, and How Can It Be Treated?
Strabismus is a condition that causes a misalignment of the eyes, in which the eyes are unable to look in the same direction at the same time. Strabismus is often colloquially referred to as being “cross-eyed” or having a “lazy eye,” but it can appear myriad manifestations. The misalignment can point in any direction and can affect either one or both eyes.
In medical terms, Strabismus is usually named and described according to the direction of the misalignment–either esotropia (inward), exotropia (outward), hypertropia (upward), or hypotropia (downward).
In addition to the cosmetic effects of Strabismus, the condition can cause a range of symptoms and significant medical issues down the line, including vision problems and loss of eyesight. The brain receives two different images, often leading it to disregard the misaligned eye, thus weakening the vision in that eye and compounding the issue. There are additional issues related to depth perception, as the brain no longer sees or properly processes the visual field in 3D. The field of vision blurs, causing significant difficulty in maintaining physical movement and balance.
