Abstract

Purpose

To evaluate the visual outcomes and changes in abnormal vascular networks and polypoidal lesions of polypoidal choroidal vasculopathy (PCV) 3 years after photodynamic therapy (PDT).

Methods

We studied 43 eyes of 43 patients with PCV for 3 years. Fundus appearance, fluorescein angiography (FA) and indocyanine green angiography (IA) findings, and visual acuity (VA) before the initial PDT were compared with those 3 months, 1 year, 2 years, and 3 years after treatment.

Results

In 24 of the 43 eyes, enlargement of the abnormal vascular network continued in a manner similar to that before PDT on IA; in eight eyes, transformation into polypoidal choroidal neovascularization (CNV) with enlargement was detected; and two eyes had the appearance of classic CNV on FA. Polypoidal lesions recurred at 3 years in 33 of the 43 eyes (77%). Mean VA (logarithm of the minimum angle of resolution) of all 43 eyes decreased to below baseline at 3 years after the initial PDT. This decrease can be explained by foveal atrophy after absorption of recurrent hemorrhagic or exudative detachment.

Conclusion

Long-term visual outcomes were not good owing to the high frequency of recurrent polypoidal lesions, as well as enlargement and neovascular changes involving abnormal vascular networks.
