Diabetic Retinopathy and Typical Retinitis Pigmentosa

Abstract

A 39-year-old woman with typical retinitis pigmentosa (RP) for 9 years and a positive family history of night blindness
was diagnosed with diabetes mellitus (DM). She developed proliferative diabetic retinopathy (PDR) during the course
of disease. She was promptly managed with pan retinal photocoagulation (PRP). PDR developing in a case of typical
RP is extremely rare and has not been reported in the literature to date. Recognition of this rare, vision threatening
complication, points out a definite need to further look deep into the pathogenesis of diabetic retinopathy.
