Abstract

PURPOSE:

To report the changes during a 1-year follow-up in visual acuity and macular thickness in a series of highly myopic eyes with choroidal neovascularization treated with bevacizumab.

METHODS:

Retrospective and multicenter study including 107 highly myopic eyes from 107 patients (mean age, 55 years) with subfoveal or juxtafoveal choroidal neovascularization. All cases were treated by one intravitreous injection of 1.25 mg bevacizumab. Best-corrected visual acuity and macular thickness with the optical coherence tomography were evaluated at baseline and then monthly during 1 year.

RESULTS:

Logarithm of the minimum angle of resolution best-corrected visual acuity at baseline averaged 0.72 (standard deviation [SD], 0.43) versus 0.53 (SD, 0.41) at 1 year after treatment (P < 0.001). Logarithm of the minimum angle of resolution best-corrected visual acuity was 0.30 or better in 49 of 107 eyes (45%) at 1 year. Thirty-three eyes (30%) gained at least 3 Early Treatment Diabetic Retinopathy Study lines (15 letters) during the follow-up. In 43 eyes (40%), reinjections were necessary because signs of choroidal neovascularization activity were still evident. The mean number of reinjections was 0.8 (SD, 1.3). Best-corrected visual acuity improvement was better in the younger group (younger than 50 years). No adverse reactions were reported.

CONCLUSION:

One intravitreal bevacizumab injection seems to be an effective therapeutic approach to treat choroidal neovascularization in highly myopic eyes. Careful monitoring is necessary to assess the need for reinjections.
