Ischemic Central Retinal Vein Occlusion

Above are photos of a 68 year old female who presented for a yearly check up of a resolved central retinal vein occlusion in the left eye. The patient came in with a complaint of blurred vision in the left eye for the past few months. Upon examination, a severe ischemic central retinal vein occlusion was found in the left eye with vision as barely light perception. In the color fundus photo, you can see dilated veins indicated by green arrows. Also in the color fundus, is an area of ischemic whitening noted by the red arrow. The fluorescein angiogram frame shows a wide area with no active blood flow (orange arrows). The SD-OCT shows hyper-reflectivity shown by the purple arrows, indicating lack of oxygen.
