Development of primary axial myopic anisometropia

Assessment of refractive errors is an integral part of the treatment of ophthalmic problems. This is especially important in pediatric patients for early diagnosis of strabismus and amblyopia. In anisometropic amblyopia, careful monitoring of the refractive error is necessary. The following case history describes a patient who developed myopic axial anisometropia at age one. It suggests that the development of myopic axial anisometropia may be different than our present understanding. We reviewed the literature and found no description of the onset of myopic axial anisometropia.
