Purpose:To report siblings of Bietti crystalline chorioretinal dystrophy. Cases and Findings:A 54-year-old male was referred to us as retinitis pigmentosa. His corrected visual acuity was 1.2 right and 1.0 left. The cornea was normal. Funduscopy showed glistening crystalline retinal deposits in both eyes. Fluorescein angiography showed patchy areas of chorioretinal atrophy. Electroretinogram(ERG)showed decreased a and b waves. He had one brother and 3 sisters. One sister,56 years of age,had had night blindness since 10 years before and impaired vision in her left eye since 5 years. Both corneas showed crystalline deposits. Both fundus showed crystalline deposits with atrophic lesions. Both cases were diagnosed with Bietti crystalline chorioretinal dystrophy. Another sister,58 years of age,showed crystalline deposits in the cornea as the sole manifestation. ERG was of negative type in her left eye. The other two siblings showed normal fundus. Conclusion:The cornea may be involved as the sole lesion in Bietti crystalline chorioretinal dystrophy.
