Journal Article

PURPOSE: To report the efficacy of treatment of neovascular age-related macular degeneration (AMD) with intravitreal bevacizumab (Avastin; Genentech, Inc, South San Francisco, California, USA) when administered in a series of three monthly injections followed by a period of observation. DESIGN: Retrospective case series. METHODS: Retrospective review of consecutive eyes with all choroidal neovascular lesion subtypes resulting from neovascular AMD treated with intravitreal bevacizumab. Treatment consisted of a pars plana injection of 1.25 mg Avastin (0.05 ml bevacizumab at a concentration of 25 mg/ml). Evaluation consisted of a complete ophthalmologic examination, including best-corrected visual acuity (VA) measurement, ophthalmoscopy, and optical coherence tomography. Eyes received a series of three monthly injections followed by a three-month period of observation. RESULTS: A total of 36 patients (37 eyes) received a series of three consecutive monthly intravitreal injections of bevacizumab. Twenty (54%) of 37 eyes had no previous treatments for neovascular AMD in the eye that received bevacizumab. Seventeen (46%) of 37 eyes had received some previous treatment before initiation of bevacizumab therapy. Intravitreal Avastin therapy produced an improvement in foveal thickness over time in eyes with neovascular AMD. This improvement was sustained during the series of three monthly injections. All eyes experienced worsening after three months without treatment. No statistically significant effect on VA was demonstrated in this series. CONCLUSION: Intravitreal bevacizumab therapy produced an improvement in foveal thickness over time in eyes with neovascular AMD when one injection was given each month for three consecutive months. All eyes experienced increased foveal thickening during the subsequent three months without treatment.
