Retinal Angiomatous Proliferation Successfully Treated with Indocyanine Green Dye-Enhanced Photocoagulation

This case series presents the use of indocyanine green dye-enhanced photocoagulation (ICG-DEP) for the treatment of retinal angiomatous proliferation (RAP). Five RAP lesions in 4 eyes of 3 patients were identified by fluorescein and indocyanine green dye angiography. The RAP lesions were treated with focal ablation of the intraretinal component using a ICG-DEP protocol. The 810-nm infrared laser in the pulsed millipulsed mode was used. The visual acuity and angiographic findings in the 3 patients with a follow-up from 18 months to 4 years are reported. The five RAP lesions were closed angiography in the 4 eyes of the 3 patients. All of the eyes had visual improvement for at least 8 months. In one stage 3 RAP lesion, there was visual improvement for 8 months until the choroidal neovascular membrane grew again. In this limited series, the procedure appeared to be safe and well tolerated with stable or improved visual acuity.
