A 60-year-old male presents to the emergency department (ED) with sudden loss of vision in his right eye. He reports that he woke up with a dark curtain over his right eye and has been unable to see out of it since. He denies any recent trauma, pain, redness, or discharge from his eyes. He has a history of diabetes and hypertension, which are well-controlled with medications.

The patient denies any headache, abdominal pain, nausea, vomiting, shortness of breath or chest pain. He also denies any recent changes in his medication regimen or lifestyle.

On examination, the patients vital signs are within normal limits. His visual acuity in the right eye is no light perception and 6/6 in the left eye. There is no relative afferent pupillary defect. Intraocular pressure is within normal limits. Slit lamp examination reveals mild cataracts in both eyes. Fundoscopic examination of the right eye has revealed a pale retina with a cherry-red spot at the macula.
