Abstract
AIMS: To report the visual outcome in a series of eyes with myopic choroidal neovascularisation treated by photodynamic therapy (PDT) followed during 48 months. METHODS: Prospective, consecutive, non-randomised interventional case series. Thirty-nine eyes from 36 highly myopic patients treated by PDT were evaluated. Best corrected visual acuity (BCVA) and fluorescein angiography were performed every 3 months. Multiple regression analysis was used to analyse changes in BCVA in relationship with initial BCVA, spherical equivalent, age, diameter of CNV and chorioretinal atrophy. RESULTS: Mean initial BCVA was 9.0 Early Treatment Diabetic Retinopathy Study lines (SD 4.3). BCVA was 10.4 lines (3.6) at month 12, 9.7 lines (SD 3.9) at month 24, 9.6 lines (SD 3.8) at month 36 and 9.6 lines (SD 4.2) at month 48. BCVA improvement was associated with initial BCVA (p<0.002), lesion diameter (p<0.04) and age (p<0.04) (multiple regression analysis). CONCLUSIONS: Our results suggest a better visual outcome for those eyes with better initial BCVA and larger lesions in younger patients treated by PDT. The poorer results for elderly patients with lower initial BCVA might lead us to consider other therapeutic approaches.
