BACKGROUND: To evaluate retinal reperfusion, @entity254 , and compensation following radial optic neurotomy for @entity63 nonperfused central @entity2994 . METHODS: Prospective, non-comparative, interventional case series of 13 @entity1 with @entity63 , nonperfused central @entity2994 who underwent decompression surgery with a radial optic neurotomy and adjunctive intraocular @entity2713 . @entity1 were followed for 1 year after surgery, and were analyzed in the preoperative and postoperative stages determining: visual acuity by ETDRS chart (LogMar) and retinal thickness with optical coherence tomography. Fluorescein angiography was performed at regular intervals to evaluate the capillary perfusion grade. Intraocular pressure was measured and fundus was examined. RESULTS: Visual acuity and retinal thickness improved in 10/13 (77%) @entity1 after surgery at 1-year follow-up. Adequate retinal reperfusion was achieved in ten of the 13 eyes. Acute reperfusion occurred in six eyes within 2 weeks of surgery and a shunt vessel at the optic disk developed in four eyes within 4 months. In the remaining three eyes, retinal reperfusion was not observed by @entity941 angiography. No complications were noted in any of the @entity1 . CONCLUSION: Surgical decompression promoted mechanical reperfusion of the occluded vessel in 10/13 (77%) cases. In 6/13 @entity1 (46%) reperfusion occurred within 2 weeks of surgery, and in 4/13 @entity1 (31%) collateral vessels formed within 4 months.
