X-linked Ocular Albinism
The prevalence of X-linked ocular albinism (XLOA) is about 1 in 60,000 males. It affects only the eyes; the color of the skin and hairs are normal. Patients usually present with reduced vision, photophobia, nystagmus, and strabismus. Many patients have problem in perceiving depth (stereoscopic vision). The visual loss is permanent, but XLOA is a nonprogressive disorder and visual acuity remains stable throughout life.
