In this report, we present a case of diabetic papillopathy that resolved after a single dose of intravitreal ranibizumab injection. A 50-year-old male presented with painless visual loss in his right eye. His visual acuity was 1/10 in the right eye and 10/10 in the left eye. Anterior segment examination of both eyes was unremarkable. Posterior segment of the right eye showed nonproliferative diabetic retinopathy with a swollen optic disc. Fluorescein angiography and optical coherence tomography were performed. There was dye leakage from the right optic disc. Optical coherence tomography revealed a significant increase in retinal nerve fiber layer thickness. Magnetic resonance imaging of the brain and orbit were normal. The patient received a single intravitreal ranibizumab (0.5 mg) injection. Two weeks after the injection, there was a marked regression of the disc swelling. Three months after the injection the optic disc was pallor and visual acuity was 6/10.
