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

PURPOSE: To evaluate the efficacy of laser photocoagulation of indocyanine green angiographically identified feeder vessels to idiopathic polypoidal choroidal vasculopathic lesions.

DESIGN: Interventional case series.

METHODS: 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.

RESULTS: 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.

CONCLUSIONS: 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.
