Partial or complete loss of vision in one eye caused by conditions that affect the normal development of vision. These conditions include strabismus, in which the eyes are crossed inward (esotropia) or turned outward (exotropia) and anisometropia, in which there is a major difference in refractive error between the two eyes from nearsightedness, fa [..]
