Objective
To evaluate short-term effects of a single photodynamic therapy (PDT) treatment with visudyne (CIBA Vision Corp.) for choroidal neovascularization (CNV) in age-ralated macular degeneration (AMD).
Methods
Thirty cases (35 eyes) diagnosed as AMD patients with classic CNV were treated with PDT. The data of visual acuity testing, fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optic coherence tomography （OCT) were used to evaluate the effects of a single treatment of PDT before and 1 week, 1 ,3 month after treatment.
Results
The visual acuity of 34 eyes were stable or improved in 3 months follow-up；and the visual acuity of 1 eye was decreased. Decrease or dispearance of fluorescein leakage from CNV was noted in 19 eyes. No serious complication occurred.
Conclusion
Single treatment of PDT for CNV in AMD can achieve short-term decrease or cessation of fluorescein leakage from CNV without loss of visual acuity.
