Woman referred for sudden, painless vision loss in right eye

A 63-year-old woman was referred to the neuro-ophthalmology service at the New England Eye Center for evaluation of 2 months of painless vision loss in the right eye.
Two months prior, the patient was in her normal state of health when, on a leisurely walk with her husband, she had sudden, painless monocular vision loss in the right eye. She did not have any other symptoms including flashes, floaters, double vision, pain with extraocular movement or jaw claudication.
The patient’s ocular history was notable for mild nonproliferative diabetic retinopathy and contact lens wear for myopia.
