Abstract

The aim of this study was to evaluate the safety and efficacy of intravitreal bevacizumab as a treatment for choroidal neovascularization (mCNV) due to pathological myopia. A consecutive series of 23 patients with mCNV treated with 1.25 mg intravitreal bevacizumab after being thoroughly informed about the off-label character of the treatment. Of the patients 6 received additional photodynamic therapy at the time of first injection. Reinjections were given every 6 weeks if intraretinal or subretinal fluid persisted. The pre-injection mean visual acuity (VA) was 0.25 (0.58 logMAR+/-0.36). During a follow up of 16.6+/-13.7 weeks 1.4+/-0.8 injections were given. Complete resorption of subretinal or intraretinal fluid was achieved in all patients. VA improved by 2.3+/-3.5 lines on average, 9 patients (39.1%) had an increase of >or=3 lines, none lost more than 1 line. Patients with bevacizumab monotherapy (n=17) had an improvement of 2.59+/-3.9 lines, 7 patients (41.2%) had an increase of >or=3 lines. No intraocular or systemic side effects were observed. In this as yet largest series of patients with mCNV treated with intravitreal bevacizumab, the treatment seemed to be effective and safe.
