Diagnosis/testing. A diagnosis of ocular albinism is probable in the presence of congenital nystagmus, iris translucency, and significant hypopigmentation of the ocular fundus periphery in males with normal skin pigmentation and foveal hypoplasia, reduced visual acuity, and aberrant optic pathway projection, as demonstrated by crossed asymmetry of the cortical responses on visual evoked potential. X-linked inheritance is documented by either a family history consistent with X-linked inheritance or the presence of typical carrier signs (irregular retinal pigmentation and partial iris transillumination) in an obligate carrier female.
