A healthy 26-year-old woman complains of 3 days of increasing “lines across my vision” and a few photopsias in the right eye. She denies ocular discomfort or systemic symptoms. She has no ophthalmic or medical history and denies recent travel or abnormal exposures. Her uncorrected acuity is 20/60 OD without improvement with pinhole and 20/20 OS. Her pupils, intraocular pressure, motility, and confrontational visual fields are normal in each eye. Results of the external examination and slitlamp examination of the anterior segment of both eyes are unremarkable. Dilated examination findings of the left eye are normal. Results of the dilated examination of the right eye reveal a clear vitreous and the findings shown in Figure 1.
