Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common genetic disorders. A 21-year-old woman presented with temporary visual loss and gross hematuria. Fundoscopy showed retinitis pigmentosa, which was confirmed by electroretinogram. Her serum creatinine concentration was 1.6 mg/dl, and her renal ultrasonography revealed bilateral polycystic kidneys; she was unaware of having this condition. In this patient, there was probably an inherited ciliary defect, which may explain the association of ADPKD and retinitis pigmentosa.
