Description: 57 year old female, recently diagnosed with accelerated hypertension, developed Right eye Combined Retinal Vein and Artery Occlusion. Posterior pole image showed severe disc edema with peri-papillary hemorrhages. There is significant retinal whitening suggestive of edema leading to the classic cherry red spot at the macula. We can also see segmented flow of blood in retinal arterioles, which is the characteristic cattle-trucking seen in central retinal artery occlusion (CRAO). Widefield image revealed multiple intra-retinal blot hemorrhages in all quadrants with tortuous dilated vessels suggestive of central retinal vein occlusion (CRVO).
