Photodynamic therapy in myopic eyes with CNV with marked leakage

Purpose: Choroidal neovascularisation (CNV) secondary to pathological myopia is an important cause of significant visual impairment in young and middle age adults globally. To assess the effect of verteporfin photodynamic therapy (PDT) in choroidal neovascularization (CNV) secondary to pathologic myopia (PM) with CNV with marked lerakage. Methods: We prospectively followed a series of 44 consecutive patients (45 eyes) with pathologic myopia (>/= 6 diopters) who received verteporfin PDT for CNV. Particular attention to the detection of leakage for neovascularization.This population was divided into two groups according to leakage of the neovascularizzation ( group A: minimum leakage; group B: marked leakage). Results: The time of follow-up was 24 months (range, 12 to 60 months). Visual acuity (VA) improved by 1 lines in group B e decreased by 2 lines on ETDRS charts in group A . The final mean VA in group B was 66,2 letters and 34,4 letters in group A. Conclusions: Verteporfin PDT has carried at a stable or improved vision in myopic eyes with CNV with marked leakage and appear to respond better to treatment respect to the CNV whit minimum leakage.
