High hyperopia in Leber's congenital amaurosis.

Few studies comment on the type of refractive errors found in patients with Leber's congenital amaurosis. The association of an uncomplicated infantile form of this condition with high hyperopia but without systemic complications has been suggested. In a retrospective study, we identified 11 patients who satisfied the criteria for the diagnosis of this subtype of Leber's congenital amaurosis. All of our cases were found to have at least +6.00 diopters of hyperopia on cycloplegic refraction. No systemic abnormalities were found in any of these children. We suggest that high hyperopia be included in the diagnostic criteria of this specific form of Leber's congenital amaurosis.
