Case 9

Patient Presentation: A 41-year-old man saw his optometrist for a routine examination. He was asymptomatic with a visual acuity of 20/20 OU; however, the optometrist was concerned for an abnormal appearing optic nerve in the right eye. Intraocular pressure and visual fields were normal. Optic disc photos were performed and are shown below.
