Abstract

PURPOSE:

To evaluate the safety and efficacy of intravitreal bevacizumab (Avastin, Genentech) for the treatment of macular edema (ME) secondary to branch retinal vein occlusion (BRVO) and hemiretinal vein occlusion (HRVO).

METHODS:

A retrospective review was performed of consecutive patients treated with intravitreal bevacizumab (1.25 mg) for ME secondary to BRVO/HRVO from May 2005 to August 2006 with follow-up through February 2007. Re-treatment was performed at monthly or longer intervals at the discretion of the treating physician.

RESULTS:

Fifty-two eyes with a BRVO and 13 eyes with an HRVO received intravitreal bevacizumab at baseline. Visual acuity improved by a mean of 12 letters at 1 month (n = 51; P < 0.001), 13 letters at 3 months (n = 61; P < 0.001), 13 letters at 6 months (n = 42; P < 0.001), 14 letters at 9 months (n = 27; P < 0.001), and 15 letters at 12 months (n = 17; P = 0.015). The mean optical coherence tomography (OCT) thickness decreased by 184 microm (P < 0.001), 131 microm (P < 0.001), 161 microm (P < 0.001), 158 microm (P = 0.002), and 205 microm (P = 0.002) at 1 month, 3 months, 6 months, 9 months, and 12 months, respectively. The mean number of injections was 1.4, 2.1, 2.7, and 3.1, and 3.3 at 1 month, 3 months, 6 months, 9 months, and 12 months, respectively. No ocular or systemic adverse events were observed.

CONCLUSION:

Improvements in visual acuity and OCT outcomes were observed during the first year after intravitreal bevacizumab in patients with ME secondary to BRVO and HRVO.
