title: Outcome of photodynamic therapy in choroidal neovascularization due to pathologic myopia and related factors.
abstract: To evaluate the outcome of photodynamic therapy (PDT) and the factors influencing its outcome in patients with subfoveal choroidal neovascularization (CNV) due to pathologic myopia. Twenty-three eyes of 21 consecutive patients who received PDT for subfoveal CNV due to pathologic myopia and who were followed for >12 months were included in the study. The relationship between the factors that might affect the treatment outcome were evaluated. Mean age was 48.7 ± 16.0 years (23-74 years). Mean follow-up was 23.2 ± 7.7 months (15-41 months). Mean logMAR visual acuity was 0.85 ± 0.24 before treatment, 0.89 ± 0.37 at 12 months, and 0.92 ± 0.46 at the final visit. Mean logMAR visual acuity did not change significantly at 12 months or at the final visit (P = 0.47 and 0.36, respectively). The baseline visual acuity strongly correlated with the final visual acuity (P = 0.001). Age showed an inverse correlation with change in logMAR visual acuity at 12 months (P = 0.01). PDT prevented significant visual loss in eyes with subfoveal CNV due to pathologic myopia. Better initial visual acuity resulted in better final visual acuity. Younger age was correlated with better treatment outcome at 12 months.
