Mesangioproliferative glomerulonephritis associated with retinitis pigmentosa

Two patients with retinitis pigmentosa and glomerulonephritis are described. The patients were unrelated and had identical renal lesions, mesangioproliferative glomerulonephritis. This may not be a chance association, and simple dip-stick urine analysis in patients with primary retinal degenerations may lead to earlier identification of renal disease.
