ABSTRACT
PURPOSE: To evaluate the effect of single-dose intravitreal bevacizumab followed by panretinal and macular grid laser, early in the course of central retinal vein occlusion (CRVO). METHODS: It is a prospective, non-randomized, interventional study of nine eyes of nine patients with <10 days origin of CRVO who received 2.5 mg (0.1 ml) intravitreal bevacizumab, followed 3 weeks later by panretinal and macular grid photocoagulation. Its effect on visual acuity and anatomical features of CRVO were studied. RESULTS: Nine eyes of nine patients (male : female = 8 : 1, mean age 54 years), with <10 days (average 2.67 days) onset of CRVO, received intravitreal bevacizumab within 7 days of presentation (average 3.1 days) followed 3 weeks later by panretinal with macular grid laser. Presenting mean baseline visual acuity was 20/320 (1.2 logarithm of the minimum angle of resolution (LOGMAR) units). All the patients showed rapid improvement in the form of rapid clearance of retinal hemorrhages, decreased optic disc swelling and venous dilation, and tortuosity. Mean final visual acuity was 20/63 (0.5 LOGMAR units). No patient showed conversion from non-ischemic to ischaemic CRVO, recurrence of macular edema, and disc collateral formation. CONCLUSION: Early intravitreal bevacizumab followed by panretinal and macular grid laser may provide visually and anatomically favourable results in a case of CRVO. It may also obviate the need for repeated injection. It requires a large randomized study to substantiate the results.
