Abstract

Aim: To evaluate safety and efficacy of surgical induction of chorioretinal venous anastomosis in the management of ISCHEMIC CENTRAL RETINAL VEIN OCCLUSION (CRVO). Materials & Methods: In a comparative clinical trial, 28 patients of ischemic CRVO were included, of whom 18 who declined surgery were considered as controls. The ten surgical cases underwent standard vitrectomy with incisions into the choroids adjacent to the partially cut major retinal veins. Mersilene suture insertion was done to induce chorioretinal venous shunt. Mild endolaser was applied. Patients were followed for 6 to 18 (mean: 10) months. Results: Clinical success in shunt development was 90%. Surgical cases had a significantly better VA improvement in comparison to controls (mean difference: 1.5 Log MAR, P: 0.001) with 80% of them showing improvement (in comparison to 28% of the controls, P: 0.016). Neovascularization developed in 39% of the control group in comparison to 0% of the surgical cases (P: 0.03). In multivariate analysis, surgery remained to be the sole significant predictor of the visual improvement. We had 3 reoperations for vitreous cavity hemorrhage, cataract, and retinal detachment.Conclusion: Surgical induction of chorioretinal venous anastomosis may result in VA improvement and prevent neovascularization in ischemic CRVO. Randomized studies are needed to strictly compare the current study modality with the natural course of CRVO and the emerging procedures like optic neurotomy in the management of ischemic CRVO.
