Abstract

PURPOSE: To evaluate the efficacy of photodynamic therapy (PDT) with verteporfin in the management of choroidal neovascularization (CNV) associated with angioid streaks.
CASE SUMMARY
Six eyes of four patients with CNV due to angioid streaks were treated with photodynamic therapy with verteporfin. Visual acuity testing, ophthalmologic examinations, photographs, and fluorescein angiograms were used to evaluate the results of PDT. Two of six eyes had subfoveal lesions, while four eyes had juxtafoveal lesions on initial examination. Conversion from a CNV to a fibrous scar lesion following PDT was observed in four eyes. Enlargement of the CNV was documented in two eyes at the final follow-up. Of a total of 6 eyes, the final best-corrected visual acuity decreased in 4 eyes and stabilized in 2 eyes.
CONCLUSIONS
Photodynamic therapy can achieve short-term cessation or decrease of fluorescein leakage from chroidal neovascularization associated with angioid streaks. However, it does not alter the course of this disease, and multiple sessions are needed. Visual prognosis is poor.

  • Figure 1. Case 3. Fundus photographs and angiographic photographs of both eyes before PDT. (A) Fundus photograph shows choroidal neovascularization with subretinal hemorrhage. (B) Fundus photograph shows macular edema. (C) Angiographic photograph shows hyperfluorescence due to choroidal neovascularization and adjacent blocked fluorescence due to hemorrhage. (D) Angiographic photograph shows hyperfluorescence due to choroidal neovascularization.

  • Figure 2. Case 3. Fundus photographs and angiographic photographs of both eyes after 5 sessions of PDT. (A)(B) Fundus photograph of the both eyes shows that CNV has changed into fibrotic tissue. (C)(D) Angiographic photograph after 5 sessions of PDT. Angiographic photograph shows no leakage within the area of the lesion, but staining on the fibrous CNV lesion.
