Hemicentral and Branch Retinal Vein Occlusion in the Same Eye

Example of a patient with two retinal vein occlusions in the same eye. A 68 year-old female with diabetes and hypertension was examined with a complaint of blurred vision of the right eye for two months. The visual acuity was 20/60 right, 20/20 left. A - The right eye had superior hemispheric retinal hemorrhages and macular edema. In addition, there was hemorrhage inferonasally in the distribution of the right inferonasal branch vein (yellow arrow). B - There was evidence of an older inferonasal branch retinal vein occlusion with large caliber collateral vessel connecting the inferonasal drainage to the inferotemporal branch retinal vein. C - A frame from the early phase fluorescein angiogram of the right eye shows good retinal perfusion. D - A magnified view of the optic disk from panel C shows the collateral vessel connecting to the inferotemporal branch retinal vein (the red arrow). E - A frame from the late phase fluorescein angiogram demonstrated late cystoid hyperfluorescence. F - OCT shows macular cysts involving the nerve fiber layer, inner nuclear layer, and outer nuclear layer as well as inspissated subfoveal exudate.
