PurposeTo report a case of peripheral exudative hemorrhagic chorioretinopathy with hemorrhagic retinal detachment and subretinal pigment epithelial hemorrhage treated with transscleral subretinal fluid drainage.ObservationsThe patient was a 70-year-old man with a 15-year history of diabetic retinopathy and age-related macular degeneration. During follow-up, he developed a sudden decrease in visual acuity in the left eye. Corrected visual acuity was 20/32 in the right eye and 20/800 in the left eye, and hemorrhagic retinal detachment and subretinal pigment epithelial hemorrhage were observed in the left eye. Pars plana vitrectomy and transscleral drainage of the subretinal hemorrhage and subretinal pigment epithelial hemorrhage were performed. We initially attempted to displace the subretinal pigment epithelial hemorrhage, but the subretinal hemorrhage was also displaced via a retinal pigment epithelial tear located in the temporal macula. The retina was completely reattached, although visual acuity in the left eye remained at 20/400.Conclusions and ImportanceThis report describes a surgical technique for hemorrhagic retinal detachment and subretinal pigment epithelial hemorrhage due to peripheral exudative hemorrhagic chorioretinopathy. We believe that transscleral subretinal fluid drainage without intentional retinal tear is a useful and safe method for patients with extensive hemorrhagic retinal detachment.
