Ocular decompression retinopathy (ODR) presents as retinal hemorrhages following acute lowering of the intraocular pressure (IOP). We review 32 articles published from 1992 to 2011 and address the pathogenesis, clinical features, management, and outcomes of ODR. ODR is defined as a multifocal hemorrhagic retinopathy that results from acute lowering of IOP and is not explained by another process. Hemorrhages occur in all retinal layers, and most patients are asymptomatic. The mean drop in IOP in ODR is 33.2±15.8 mm Hg (range, 4-57 mm Hg). Eighty-two percent are diagnosed by the first postoperative day, all within 2 weeks. ODR resolved in a mean of 13±12.4 weeks (range, 2-72 weeks). Vitrectomy was required for vitreous and subhyaloid hemorrhage in 14% of cases. Visual outcomes are generally good, with 85% of eyes returning to baseline vision. Although ODR infrequently results in significant ocular morbidity, gradual reduction in IOP might prevent this complication.
