Implication

Randomized double-blind trial reveals sustained visual acuity preservation with verteporfin in age-related macular degeneration, highlighting durable benefits for predominantly classic lesions.

Key Points

  • To evaluate 24-month visual acuity and fluorescein angiographic outcomes of photodynamic therapy with verteporfin in patients with subfoveal choroidal neovascularization caused by age-related macular degeneration.
  • Two multicenter, double-masked, placebo-controlled, randomized clinical trials conducted across 22 ophthalmology practices in Europe and North America.
  • Enrolled 609 patients with subfoveal choroidal neovascularization lesions measuring ≤5400 µm and best-corrected visual acuity between 20/40 and 20/200, assigned to verteporfin (n=402) or placebo (n=207).
  • Follow-up evaluations occurred every 3 months for 24 months with repeat treatment administered for persistent fluorescein leakage, using an intent-to-treat primary outcome of visual acuity loss <15 letters.
  • At month 24, 53% (213/402) of verteporfin-treated patients lost fewer than 15 letters of visual acuity compared with 38% (78/207) of placebo-treated patients (P < .001).
  • Among patients with predominantly classic lesions at baseline, 59% (94/159) receiving verteporfin lost fewer than 15 letters compared with 31% (26/83) receiving placebo (P < .001), with no significant difference observed for minimally classic lesions.
  • Trial completion at month 24 was 87% (351/402) with verteporfin and 86% (178/207) with placebo, with few additional photosensitivity reactions or injection-site complications during year two.
