Anisometropia

 
Home
    On of the most profound risk factors for amblyopia is a substatinal difference in refractive error between the eyes, called "ANISOMETROPIA." Unequal farsightedness (hyperopia) greater than 1.5 diopters occurs in about 1.1% of children, is more common in the left eye, and is more common with nasolcrimal duct obstruction. Anisometropic myopia is less likely to cause amblyopia. Anisometropia can accompany small- or large-angle strabismus, and is detected by photoscreening, or by patched acuity screening.
