Abstract

PURPOSE: To report a case of central retinal vein occlusion (CRVO) that had vitrectomy with radial optic neurotomy (RON), but the retinal blood flow (RBF) was still reduced 1 year later. DESIGN: Interventional case report. METHODS: An 80-year-old woman had undergone vitrectomy and RON for a CRVO. She had a complete ophthalmic examination, including the RBF analysis using the dye dilution method before and after RON. RESULTS: Seven months after RON, her visual acuity improved from 20/50 to 20/25, and her foveal thickness was decreased from 733 to 213 μm. Indocyanine green angiography demonstrated chorioretinal anastomoses. At 1 year postoperatively, the RBF was reduced from 23.2 to 18 0.1 pixel2/s, and the foveal thickness was increased to 767 μm. Her visual acuity decreased to 20/100. The chorioretinal anastomoses were still patent. CONCLUSIONS: These results demonstrate that a further reduction of RBF can occur after RON, and blood flow in the chorioretinal anastomoses may be insufficient to prevent the event.
