Intravitreal bevacizumab to treat myopic choroidal neovascularization: 2-year outcome.
BACKGROUND
Myopic maculopathy is the leading cause of subfoveal choroidal neovascularization (CNV) among patients under 50 years of age. New antiangiogenic drugs are being used off-label to treat myopic CNV and the short-term outcome of these therapies has been reported. The aim of this study is to report the changes in best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) in highly myopic CNV treated by intravitreal bevacizumab at 2 years.


METHODS
Prospective non-randomized, interventional case series study of 19 highly myopic eyes from 18 patients with subfoveal and juxtafoveal CNV treated by three monthly intravitreal injections of 1.25 mg bevacizumab. Patients were evaluated for BCVA and OCT at baseline and then monthly for 2 years.


RESULTS
Eleven eyes were naive for treatment and eight eyes had been previously treated by photodynamic therapy. LogMAR BCVA averaged 0.54 (SD 0.25, range 0.2-1.0; Snellen 20/69) at baseline; 0.40 (SD 0.35, range 0.0-1.2; Snellen 20/50) at 1 year; and 0.47 (SD 0.31, range 0.0-1.0; Snellen 20/59) at 2 years (p = 0.04 and p = 0.20, respectively, Student's t test paired data). Re-treatment was performed in four eyes during the first year: three eyes at month six and one eye at month 12. Four eyes required one re-injection during the second year at months 14, 18, 20, and 24. Neither ocular nor systemic adverse reactions were detected.


CONCLUSIONS
Intravitreal bevacizumab seems to be effective for subfoveal and juxtafoveal CNV in highly myopic eyes. BCVA gain decreases and is no longer significant by the end of the second year.
