A 21-year-old girl presented 15 days post-blunt injury with pain in right eye (OD). The best corrected visual acuity (BCVA) was 20/240 OD, 20/20 left eye (OS). On slit-lamp examination, the hyphema (2 mm) and intraocular pressure (IOP) – 44 mmHg were noted. Berlin's edema was noted. The OS was normal. Following anterior chamber (AC) wash, the vision improved to 20/80 with normal IOP. However, the fundus revealed multilayer hemorrhages with unusually sclerosed peripheral vessels in a well-demarcated circumferential pattern, better appreciated on fundus fluorescein angiography (FFA) [Figure 1]. Detailed systemic investigations (hematologic, autoimmune, and gynecologic) ruled out thromboembolic risk factors. The final BCVA was 6/9 with sclerosed vessels. Decompression retinopathy presents as asymptomatic multilayer hemorrhages[1] with the mean time to diagnosis of 1.5 ± 2.0 days.[2],[3] The proposed mechanisms include mechanical, vascular, and autoregulation alterations.[4] It may later cause dysfunction in autoregulation due to IOP changes. Altered retinal autoregulation due to prolonged high IOP might be the possible cause of occlusion and rare association in this case.
