INTRODUCTION: To evaluate intravitreal bevacizumab therapy for choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).

MATERIAL AND METHODS: A retrospective review between June 2006 and May 2008 of patients with CNV secondary to AMD was conducted. All patients were treated with intravitreal injection of bevacizumab (1.25mg) once a month during a 3-month-period. The mean evaluation criteria were the best-corrected visual acuity (BCVA) logMar testing before and one month after the third injection. All eyes underwent an angiography and an optical coherence tomography before injections to define the activity and the type of CNV and then to evaluate the persistence of leakage (macular edema, subretinal fluid, and pigment epithelial detachment) after treatment. Then treatments were left to the investigator's discretion during the following six months.

RESULTS: Seventy-one eyes of 66 patients were enrolled. There were 65% occult CNV, 20% classic CNV, and 15% combined. A significant improvement in BCVA was observed, from 0.88±0.57 to 0.77±0.60 (p=0.001), one month after the third injection. At this time, 57.7% of the eyes required a reinjection because of leakage persistence. A concomitant treatment with intravitreal triamcinolone injection and/or photodynamic therapy was necessary for 8% of nonresponder eyes. Six months after initial treatment, a complete resolution of exudative signs was not obtained for 33.8% of eyes. The average number of injections was 3.85±0.96 during the 9-month follow-up. BCVA stability was observed at 4, 6 and 9-month follow-ups (F(71.2)=1.54; p=0.46). Three complications occurred: one endophthalmitis, one retinal tear, and one vitreous hemorrhage secondary to a macular hemorrhage.

DISCUSSION: Mean BCVA significantly improved at one month after three consecutive monthly intravitreal injections of bevacizumab. However, most eyes required a reinjection.

CONCLUSION: In spite of improvement in BCVA, leakage of the CNV persisted in most eyes after three monthly intravitreal injections of bevacizumab. Then retreatment and sometimes concomitant treatment was necessary to obtain complete resolution of exudative signs and BCVA stability.
