Efficacy of intravitreal bevacizumab to treat retinal angiomatous proliferation stage II and III.
OBJECTIVE
To evaluate the efficacy of intravitreal bevacizumab to treat retinal angiomatous proliferation (RAP) stages II and III.


METHODS
A retrospective, interventional, nonrandomized multicentric study was performed. The files, optical coherence tomography (OCT) scans, indocyanine green, and fluorescein angiograms of patients with RAP stages II and III who had been treated by intravitreal bevacizumab were retrospectively examined. Final visual acuity, number of injections, and appearance of adverse events were considered as main outcome indicators.


RESULTS
Twenty-six eyes from 24 patients (9 male and 15 female) were treated by intravitreal bevacizumab. Fourteen eyes presented RAP stage II and 12 eyes presented RAP stage III. Mean age was 76+/-9 and 79+/-6 years, respectively. Mean initial best-corrected visual acuity (BCVA) was logMAR 0.60+/-0.24 and 1.13+/-0.37, respectively. Mean BCVA was 0.62+/-0.26 and 1.06+/-0.37, respectively, at 6 months (p=0.96 and 0.10, respectively, Student t test for paired data) and 0.63+/-0.26 and 1.04+/-0.37, respectively, at 12 months (p=0.82 and p=0.06, respectively, Student t test for paired data). The average number of injections during the first year was 3.4 and 3.2, respectively.


CONCLUSIONS
Intravitreal bevacizumab may stabilize visual acuity during the first year in RAP lesion stage II and III. Visual prognosis seems to be better in RAP II lesions.
