What Is Lazy Eye?
4. Causes
Lazy eye can be caused by strabismus (misaligned eyes where one eye is favored strongly and fixation is not alternated) or anisometropia (where one eye is inhibited to eliminate the abnormal interaction caused by one focused and one defocused image).
Another cause of amblyopia is visual deprivation due to understimulation or disuse of the retina. This can be due to ptosis, cataract, surgical lid closure, and corneal opacities. Besides these three main causes, amblyopia may also be due to organic causes. Organic amblyopia is often irreversible due to an eye condition that limits the improvement of vision. Examples include retinoblastoma and toxoplasmosis chorioretinitis.
