Abstract
Purpose
To evaluate visual outcomes in patients with high myopia after juxtafoveal choroidal neovascularization (CNV) treated with argon green laser photocoagulation.
Patients and Methods
We retrospectively analyzed 23 eyes of 21 patients with high myopia (>6.0 diopters and/or axial length >26 mm) with juxta foveal CNV treated with direct Argon green laser photocoagulation. Mean age at diagnosis was 49.08±12.20 years (range, 29 to 71). Mean follow-up was 54.26±26.18 months (range 18 to 96).
Results
Best corrected visual acuity (BCVA) before treatment was 0.09±0.10 (range, 0.01 to 0.40). Two months after treatment it was 0.14±0.12 (0.01 to 0.6), significant difference (p=0.02, Student's t-test for paired data) and after six months 0.19±0.14 (0.01 to 0.5) (p=0.0002). Mean BCVA decreased with follow-up, to 0.19±0.15 (0.01 to 0.4) after two years, 0.16±0.15 (0.01 to 0.5) after three years and 0.16±0.19 (0.01 to 0.7) after four years, with no significant improvement after the third year (p=0.04). In two cases CNV reappeared.
Conclusions
Direct argon green laser photocoagulation in high-myopia juxtafoveal CNV can improve BCVA initially for between two and 24 months. The improvement fades with time, and is no longer significant after the third year.
