Correlation between aqueous flare and chorioretinal neovascularization in age-related macular degeneration following intravitreal bevacizumab injections.

Prospective evaluation of aqueous flare following intravitreal bevacizumab (Avastin, Genentech Inc., San Francisco, CA, USA) injections in eyes with choroidal neovascularization due to age-related macular degeneration.Sixteen eyes of eight patients were recruited. Aqueous humor flare was determined by laser flare meter every month after one intravitreal injection of 1.25mg of bevacizumab at baseline followed by a second injection at month3 (day 100±21days). Four patients received an injection at month6 (±10days), and one patient received an injection at month7.Two months after the first intravitreal bevacizumab injection, flare values decreased from 10±5.57 (mean±standard deviation) to 5.2±1.69photon count/ms (P=0.0207) and from 8.3±3.59 to 5.4±0photon counts/ms, 2months after the second injection (P=0.02).Significantly decreased aqueous humor flare levels were noted after repeated injections of bevacizumab.
