Combined photodynamic therapy and intravitreal triamcinolone for nonsubfoveal choroidal neovascularization

Retina. 2005 Sep;25(6):685-90. doi: 10.1097/00006982-200509000-00001.

Abstract

Purpose: To examine the 12-month results for a group of patients with nonsubfoveal choroidal neovascularization who were treated with combined photodynamic therapy (PDT) with verteporfin and intravitreal triamcinolone acetonide.

Methods: Patients with nonsubfoveal choroidal neovascularization, which was defined as either juxtafoveal or extrafoveal neovascularization, were treated with PDT immediately followed by an intravitreal injection of 4 mg of triamcinolone acetonide. Need for retreatment was based on fluorescein angiographic evidence of leakage at 3-month follow-up intervals. The main outcome measures were visual acuity and the proportion of patients developing subfoveal extension.

Results: Of the 15 patients, 9 were women and 6 were men (mean age +/- SD, 80 +/- 7.5 years). The mean baseline visual acuity was almost 20/60 (mean logMAR = 0.46), and 14 of the 15 eyes had juxtafoveal choroidal neovascularization. At 3, 6, and 9 months, the patients had significant improvement in the mean visual acuity (P = 0.002, 0.001, and 0.007, respectively), but at the end of the 12-month follow-up period, the mean visual acuity was slightly worse than 20/40 (mean logMAR = 0.34), which was not statistically significant at an alpha level adjusted for multiple comparisons of .013 (P = .057) as compared with the baseline visual acuity. One patient had subfoveal extension of choroidal neovascularization. The mean number of treatments was 1.9. Three patients (20%) developed an intraocular pressure of >24 mmHg during follow-up, a threshold used to institute pressure reduction therapy. No patient developed endophthalmitis.

Conclusion: The number of patients in this pilot study was limited; however, the visual acuity response and the low incidence of subfoveal extension suggest that PDT combined with intravitreal triamcinolone for the treatment of nonsubfoveal choroidal neovascularization merits further investigation as a first-line treatment.
