Macular Branch Retinal Vein Occlusion with Subretinal Fluid
Fundus images from an 86 year old woman with CREST syndrome who suddenly developed central blurring of the right eye. Best corrected visual acuity was 20/63 on the right. A - Monochromatic fundus photograph shows an inferotemporal macular branch retinal vein occlusion with a denser area of intraretinal hemorrhage surrounded by an area of sparser hemorrhage. B - Frame from the mid-phase fluorescein angiogram showing dilated, telangiectatic capillaries inferior to the fovea. The intraretinal hemorrhage is so dense that capillary perfusion is impossible to assess. C - Frame from the late phase fluorescein angiogram showing late intraretinal hyperfluoreacence. D - False color map OCT display showing that the area of the retinal thickening colocalizes with the area of the intraretinal hemorrhage. E - OCT line scan showing marked thickening of the outer nuclear layer, moderate thickening of the inner nuclear layer, and subretinal fluid under the fovea (yellow arrow).
