Abstract: :
Purpose:To evaluate the efficacy of different surgical techniques for the management of ischemic central retinal vein occlusion (CRVO) Methods:: Retrospective and descriptive study in patients with ischemic CRVO with visual acuity (VA) <20/100 or those whose VA decreased more than 50% during follow–up, an area over 10 disc diameter of nonperfused retina, and afferent pupillary defect. Eyes with rubeosis or previous laser treatment were excluded. Rubeosis, intraocular pressure (IOP), visual acuity (VA) were evaluated clinically, fluorescein angiography (FA) were also performed. Follow–up was at least 1 year. Results: 69 eyes were evaluated. Age ranged from 32 to 94 years, (average 63.87 years). 20 patients: chorio–retinal (c–r) erbium–yag anastomosis, 9 patients: c–r pulsed electron avalanch knife (PEAK) anastomosis, 5 patients: c–r diode (810 nm) anastomosis, 10 patients: radial optic neurotomy, 10 patients: intravitreal triamcinolona (IT), 9 patients: pars plana vitrectomy (PPV) and 6 patients: VVP and IT. VA increased in anastomosis c–r diode, VA was stable in all vitrectomy group, neurotomy group and IT group; it was decreased in erbium and peak anastomosis group. Conclusions:: Different surgical techniques appear to be an effective treatment for ischemic OVCR to achieve improvement and/or stabilization of VA with minimal complications.
