Branch Retinal Vein Occlusion - Ischemic

You should look at the normal Fluorescein Angiogram first. In this photo, the capillary supply below the macula is partially missing, and the capillaries that remain are coarsened, with abnormal bulb like dilated segments. The absence of capillaries puts this branch vein occlusion into the category of ischemic, which may change management. If macular swelling is present, it is advisable to watch it without treatment for several months, as the swelling in such cases often resolves spontaneously. Also, the patient needs to be educated that the visual acuity is likely to be impaired from the absent circulation regardless of what happens to any concomitant swelling.
