Treatment of high myopic choroidal neovascularisation with intravitreal bevacizumab

Purpose. - To evaluate the safety and efficacy of intravitreal bevacizumab (IVB) in the treatment of high myopic choroidal neovascularization (CNV). Materials and methods. - Retrospective study of 16 eyes of 16 patients with high myopic choroidal neovascularization treated with first-line IVB (1.25 mg/0.05 mL) with a one-year follow-up. All patients underwent a complete baseline (M0) ophthalmologic examination, including the measurement of best corrected visual acuity (BCVA), biomicroscopic and fundus examination, fluorescein and indocyanine green angiography, and optical coherence tomography. Patients were followed monthly. Additional IVB was administered when persistent or additional retinal exudation was observed. The main study parameters were visual acuity at 1, 6 and 12 months and the progression of exudation on OCT and angiography. Results. - Mean age was 63 +/- 14 years and spherical equivalent was -15.4 +/- 7.4 diopters. Baseline BCVA was 0.75 +/- 0.5 logMAR. Mean follow-up was 15 +/- 2 months. The average number of IVB was 2.4 +/- 1.2 injections. Metamorphopsia decreased in all patients and completely disappeared in fourteen eyes. Mean BCVA was 0.5 +/- 0.3 logMAR at M1 and 0.6 +/- 0.5 logMAR at M6 and M12. No adverse events related to the intravitreal injections were observed. Conclusion. - Our study showed that IVB (Avastin (R)) is effective in the treatment of high myopic CNV. Moreover, only a small number of intravitreal injections were required to treat this condition.
