Diabetic papillopathy with macular edema treated with intravitreal ranibizumab

Abstract

We report a case of diabetic papillopathy that demonstrated a resolution of optic disk swelling and rapid visual recovery when intravitreal ranibizumab was administered. A 51-year-old male presented with acute painless visual loss in his right eye. His vision was 20/320 in the right eye and 20/50 in the left eye. Fundus examination of the right eye showed nonproliferative diabetic retinopathy with macular edema and a swollen optic disk. Fluorescein angiography showed dye leakage from the right optic disk. Optical coherent tomography revealed a significant increase in retinal nerve fiber-layer thickness. Magnetic resonance imaging of the brain was normal. The patient received a single intravitreal ranibizumab (0.5 mg) injection. Two weeks following injection, there was marked regression of the disk swelling and improvement of macular edema, with vision improving to 20/100. Three months following injection, there was complete resolution of the optic disk swelling. No further treatment was required.
