Outcome measures were best corrected visual acuity (BCVA) and optical coherence tomography (OCT) central macular thickness. Injections were repeated if no further improvement was observed.Results: Twenty-nine eyes of 29 patients were included. The average BCVA improved from 20/148 at baseline to 20/106 at twelve weeks (P = 0.041). Of the 29 eyes, 25 (86.2%) had stable or improved BCVA. Average mean central macular thickness measured by OCT improved from 351 μm at baseline to 278 μm at 12 weeks (P = 0.003). Stabilization of vision and improved OCT central macular thickness were maintained for at least eight weeks following only a single injection in the majority of eyes. During the three months of follow up, only five eyes (17.2%) required repeat injections, with only three (10.3%) requiring retreatment at eight weeks and none at four weeks. No significant ocular or systemic side effects were observed. Conclusion: This short-term data suggests that bevacizumab appears to be a safe and effective treatment for neovascular AMD. Injections as frequent as every month do not appear to be necessary since initial treatment effect appears to be maintained for at least eight weeks in almost all of our patients.Keywords: retina, Avastin®, bevacizumab, neovascular age-related macular degeneration, AMD Nicola G GhaziTyler Q KirkRobert M Knapeet alDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2010, Iss default, Pp 307-314 (2010)
