Laser photocoagulation of indocyanine green angiographically identified feeder vessels to idiopathic polypoidal choroidal vasculopathy.

Abstract

To evaluate the efficacy of laser photocoagulation of indocyanine green angiographically identified feeder vessels to idiopathic polypoidal choroidal vasculopathic lesions. Interventional case series. Fifteen eyes of 14 consecutive patients with idiopathic polypoidal choroidal vasculopathy lesions treated by laser photocoagulation of indocyanine green angiographically identified feeder vessels were investigated. In 10 of the 15 eyes, serous retinal detachment of sensory retina in the macula disappeared after photocoagulation of the feeder vessels. The best-corrected visual acuity improved by 2 or more lines in eight of the 15 eyes and worsened in two eyes during the mean follow-up period of 13.6 months. Laser photocoagulation targeted exclusively to the feeder vessels supplying the idiopathic polypoidal choroidal vasculopathy lesions is a safe and effective method and can improve vision in eyes in which a serous retinal detachment is present in the macula. Indocyanine green angiography-guided laser photocoagulation should be considered as an optional treatment for idiopathic polypoidal choroidal vasculopathy.
