Case 5-8. Central Retinal Vein Occlusion with Cystoid Macular Edema and Lamellar Hole

Clinical Summary

An 87-year-old woman with a history of non-ischemic central retinal vein occlusion in both eyes was examined. She had received grid laser photocoagulation in the right eye one month earlier Slit-lamp biomicroscopy (A) revealed significant cystoid macular edema, engorged retinal veins, and blot and flame-shaped hemorrhages scattered throughout the posterior pole. The visual acuity in this eye was 20/200. Diffuse late leakage was evident on the fluorescein angiogram (B) consistent with cystoid macular edema.

Optical Coherence Tomography

A horizontal OCT tomogram (C) showed an increased retinal thickness of 670 ijm in the fovea. The reduced optical backscatter signal observed intra retina II v was consistent with cvstic fluid accumulation, and a large foveal cvst was observed which extended to the inner limiting membrane.
