Purpose: To evaluate the visual outcome of photodynamic therapy with verteporfin in patients with subfoveal choroidal neovascularization (CNV) caused by pathologic myopia.
Methods: Retrospective and noncomparative analysis of 42 patients with CNV secondary to pathologic myopia recruited between September 2001 and 2003, who were treated with a standard regimen of photodynamic therapy with verteporfin.
Results: Forty-two patients were followed up for 12 months; 15 out of 42 completed 24 months of follow-up. Initial visual acuity ranged from 1/10 to 5/10 with a mean of 1.6/10. Twenty-five (56.7%) eyes had stable or improved visual acuity at 12 months with a mean of 2.5/10. In the group of patients who completed 24 months of follow-up, six eyes (39.9%) had stable or improved visual acuity with a mean of 1.6/10 at 1 year and 1.25/10 at 2 years. The average photodynamic therapy treatment required in 1 and 2 years were 1.5 and 2.1, respectively, and they are less than those reported by the Verteporfin in Photodynamic Therapy (VIP) study.
Conclusion: Photodynamic therapy with verteporfin for subfoveal choroidal neovascularization caused by pathologic myopia maintained a visual benefit at 1 and 2 years.
