Several treatments of choroidal neovascularization (CNV) in pathologic myopia are proposed today. We compared, by retrospective analysis, the visual outcome at 12 and 24 months between patients treated by photodynamic therapy (PDT) and patients who underwent surgical removal of CNV.
we reviewed, after 2 years of follow–up, clinical and angiographic findings of 25 patients with severe myopia and subfoveal classic CNV. The patient population was divised in 2 groups: 11 patients treated by PDT and 14 patients treated by surgery.
An intermediary analysis was performed at 12 months and showed a significant visual acuity benefits for the group treated by surgery. The final results at 24 months showed no significant difference in the visual outcome between the 2 groups.
Even if the surgical removal is more beneifc for the visual outcome in the first year, the final visual acuity is quite similar for the 2 groups after 2 years of follow–up. In the light of these results we conclude that in CNV of pathologic myopia, PDT is preferable to surgical removal because it is safer.
