Eligibility Criteria
You may qualify if you...
Patients have been recruited into the study by referral from an ophthalmologist or pediatrician.
Entrance into the study was dependent upon clinical evidence of decreased or absent pigmentation in skin, hair, and/or eyes.
The definition was purposefully broad to include the broad range of phenotype variations and clinical heterogeneity.
The purpose of the study id to be able to document iris and retina/choroidal pigmentation and correlated these finding with visual function.
