A 69-year-old woman presented to the emergency room complaining of sudden vision loss, which had begun two days previously, in her left eye. She also suffered from systemic amyloidosis and renal failure requiring hemodialysis.
On presentation, her best-corrected visual acuity was 20/20 in the right eye and 20/15 on the left. This took into account a search of the visual field for the best acuity.
During funduscopy, the retina of the left eye was found to be chalky and pale except for the macular and the papillomacular bundle areas. Fluorescein angiography was performed, revealing a central artery obstruction with sparing of the cilioretinal circulation.
