Purpose: To evaluate feeder vessel treatment of recurrent CNV associated with the scar of previous MPS-type treatment. Methods: Feeder vessels were treated in 16 consecutive eyes based on FA and High-Speed ICG images. Vision was measured at 6 months and 12 months and compared to baseline visual acuity prior to treatment. Results: 15/16 had classic CNV. All had feeder vessel treatment within the scar. One had additional feeder vessel treatment outside the scar. Treatment of feeder vessels attenuated or closed the CNV in all patients. Vision improved ≷2 lines in 7/16 and remained stable (+/–2 lines) in 9/16 at 6 months. Twelve patients were followed for 12 months or more. In this group 4/12 improved ≷2, 7/12 remained stable and 1/12 had vision decrease by 6 lines. No patients experienced a loss of more than 6 lines at any point during the study period. Conclusion: Recurrent CNV can be safely and effectively treated using the feeder vessel technique.
