PURPOSE: To investigate the effects of photodynamic therapy (PDT) on subfoveal choroidal neovascularization (CNV) secondary to reticular pattern dystrophy (RPD) of the retinal pigment epithelium. DESIGN: Open-label, prospective, interventional case series. METHODS: Thirteen eyes diagnosed with subfoveal CNV associated with RPD were considered. Complete ophthalmic examinations were performed at baseline and thereafter at three-month intervals for three years. Primary outcome measure was the number of eyes with <15 letters loss (approximately <3 lines) at 12, 24, and 36 months, compared with baseline. Secondary outcome measures included CNV progression and number of PDT sessions. RESULTS: Seven eyes showed a decrease in best-corrected visual acuity of at least three lines at three-year examination. Each eye received a median number of treatments of two, zero, and zero in years one, two, and three, respectively. CONCLUSIONS: PDT does not appear to guarantee longterm vision stabilization in RPD-related subfoveal CNV, and alternative therapies should be investigated.
