Branch Retinal Vein Occlusion with Cystoid Macular Edema

Branch Retinal Vein Occlusion with Cystoid Macular Edema. 58-year-old woman with obvious macular blood and retinal thickening. However, the map of the retina displays multiple thin quadrants (noted in red). The disconnect between the artificially thin retina versus the truly thickened retina in this case is due to a segmentation error. When the automatic segmentation lines are misplaced, then the retinal thickness will be calculated incorrectly.
