Photodynamic therapy with or without intravitreal triamcinolone acetonide for symptomatic polypoidal choroidal vasculopathy.
OBJECTIVE
To evaluate the outcome of verteporfin photodynamic therapy (PDT) with or without intravitreal triamcinolone acetonide (IVTA) for the treatment of symptomatic polypoidal choroidal vasculopathy (PCV).


METHODS
Retrospective analysis of PCV patients who underwent PDT with or without IVTA with follow-up of 2 or more years. Changes in best-corrected visual acuity (BCVA), proportion of eyes with moderate visual loss (3 or more lines), and complications were compared between patients with or without IVTA.


RESULTS
Twenty-seven eyes of 27 patients were analyzed, with 12 eyes treated by PDT monotherapy and 15 eyes treated by combined PDT with IVTA. The baseline characteristics of both groups were similar. At 1 year, the mean logMAR BCVA for the PDT monotherapy group improved from 0.74 to 0.58 (P = 0.011), whereas the combined PDT and IVTA group improved from 0.84 to 0.74 (P = 0.17). At 2 years, the mean logMAR BCVA for the monotherapy and combined treatment groups were 0.62 and 0.84, respectively, and the changes compared with baseline were not statistically significant. No significant difference was found in the mean logMAR BCVA, the mean line of visual changes, and the mean number of PDT treatments between the 2 groups at 1 and 2 years. One (8.3%) and 4 (26.7%) eyes in the monotherapy and the combined groups lost 3 or more lines at 2 years, respectively. Patients who had combined PDT with IVTA were more likely to develop cataract requiring surgery and ocular hypertension (P = 0.043 and 0.046, respectively).


CONCLUSIONS
PDT reduced the risks of visual loss in patients with symptomatic PCV in the short term but the effect might not be sustained after 1 year. The adjunctive use of IVTA during PDT did not appear to result in additional benefit for treating PCV.
