Changes is Visual Function after Photodynamic Therapy (PDT) in Patients with Choroidal neovascularization

Abstract

Abstract: : Purpose: To investigate patient near image preferences prior to and following photodynamic therapy (PDT) with Verteporfin. Methods:Seventeen consecutive patients with neovascular age-related macular degeneration (AMD) were given examinations consisting of: Near acuity, with a positive and negative image Near Acuity Test; Color vision; and Contrast Sensitivity. Test were done preoperatively, 1 week and 3 months post standardized PDT. Results:Preoperatively none of the patients preferred the negative image. One week after PDT all but one patient preferred the negative image and near vision improved more significantly on the negative image reading card than the positive. Three months after PDT all but one patient preferred the negative image. The difference between positive and negative reading tests was significant Conclusion:Preliminary clinical data describe the significant change from positive to negative images after PDT
