A case report of central retinal vein occlusion with ulcerative colitis that recovered without any treatments

Background : A central retinal vein occlusion (CRVO) is a rare complication of ulcerative colitis. Case report : We report a teenager with a CRVO that resolved without ophthalmic medication. A 19-year-old man presented with decreased vision in his right eye. He had a history of UC. At the initial examination, the best corrected visual acuity was 0.4 in the affected eye. Dilated and tortuous retinal veins, retinal bleeding and cystoid macular edema were demonstrated and the foveal thickness calculated with optical coherent tomography was 627μm in the right eye. His other ocular findings were within normal limits. One year later, without any ophthalmic treatments, the foveal thickness recovered within normal limits, and his ocular signs and symptoms were completely resolved. Conclusions : We report a young case of ulcerative colitis that developed CRVO, and then recovered spontaneously. The natural course of carefully selected cases of CRVO might be good without any ophthalmic treatments.
