Ocular decompression retinopathy (ODR) presents as retinal hemorrhages following acute reduction of intraocular pressure (IOP). A sudden increase in retinal intravascular flow due to hypotony and defective autoregulation of blood vessels due to longstanding glaucoma consequently lead to retinal hemorrhages. Retinal hemorrhages in ODR should be distinguished from differential diagnoses including central retinal vein occlusion (CRVO), valsalva retinopathy, and ocular ischemic syndrome, since therapies for these diseases are different. We report a case of multiple retinal hemorrhages in ODR mimicking CRVO.

Case Report
A 74-year-old female patient was referred to Daegu Fatima Hospital due to sudden ocular pain and sudden decrease in visual acuity in the right eye. Her best-corrected visual acuity was 20 / 200 in the right eye and 20 / 25 in the left eye and IOP was 68 mmHg in the right eye and 14 mmHg in the left eye. There were signs of acute angle closure including corneal edema, mildly dilated pupil, and shallow anterior chamber in the right eye. The optic discs had slight disc hyperemia in the right eye under a high IOP state. The patient was treated with intravenous mannitol 15% 250 mg, acetazolamide two tablets, and topical dorzolamide-timolol and pilocarpine 2% eye drops.
