November 19, 2011 updated by: Joao Nassaralla, Instituto de Olhos de Goiania
To report the short term anatomic and visual acuity response after intravitreal injection of bevacizumab (Avastin, Roche, Rio de Janeiro, Brazil) in patients with choroidal neovascularization secondary to age-related macular degeneration.

Detailed Description

We conducted a retrospective study of 500 eyes with choroidal neovascularization secondary to age-related macular degeneration who were treated with at least two (initial and one month after) intravitreal injection of 1.25 mg bevacizumab and had a follow-up of at least 2 months. Patients underwent Snellen visual acuity testing, optical coherence tomography (OCT) imaging and ophthalmoscopic examination at baseline and follow-up visits.
