PURPOSE: To provide further information on verteporfin photodynamic therapy in occult with no classic choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). METHODS: Verteporfin therapy was administered at baseline and then at months 3, 6, and 9, if fluorescein leakage from CNV was evident on angiography. RESULTS: Of 202 patients enrolled, 184 completed 12 months. Each patient was treated in one eye only. All study eyes received verteporfin therapy at baseline, with a progressive decrease in the number treated at subsequent visits (mean 2.5 treatments during 12 months). The mean change in visual acuity letter score from baseline to month 12 was -11.9. At month 12, 164 eyes (82.4%) had lost <30 letters of visual acuity, 123 eyes (61.8%) had lost <15 letters, 78 eyes (39.2%) had lost <5 letters, 31 (15.6%) had >5-letter increase, and 7 (3.5%) had >15-letter improvement. The percentage of eyes with fluorescein leakage from CNV decreased from 75.5% at month 3 to 25.1% at month 12. Adverse events were documented for 54% patients. Few patients had treatment-associated adverse events (7%). Acute severe visual acuity decrease occurred in two eyes (1%), one of which had visual acuity that returned to baseline by the next follow-up visit. CONCLUSIONS: This study provides additional evidence that over 12 months, verteporfin is generally well tolerated and maintains or improves visual acuity in over one-third of eyes containing occult-only CNV. Verteporfin also improved anatomical outcomes by reducing leakage from CNV in at least two-thirds of eyes.
