title: Three cases of grouped pigmentation of the retina.
abstract: We examined three patients with congenital grouped pigmentation of the retina by means of electroretinography, electro-oculography and visually evoked cortical potentials. Two patients were affected bilaterally and 1 had a unilateral condition. Electrophysiological findings were normal in all patients, and no inheritance patterns for the disease were found in any of the patients' histories. Only 5 cases of this disease have been reported in Asian countries in recent years. We believe that our patients contribute to the sample of such cases regarding racial prevalence.
