Abstract
PURPOSE: After the 12-month interim safety analysis, we investigated the 24-month primary endpoint outcomes of drusenoid pigment epithelial detachment (dPED) after laser and intravitreal anti-VEGF treatment. METHODS: Twenty-one patients with treatment-naïve bilateral intermediate AMD with dPED and visual acuity ≤ 83 letters (Snellen 20/23) were enrolled. The subject eye received low-energy PASCAL® laser (532 nm) treatment, and the fellow eye was used as the control. Intravitreal injections were administered at 3-month intervals from baseline to 12 months. Treatment outcomes, safety and development of advanced AMD lesions were analyzed. RESULTS: The mean drusen area and dPED height were significantly reduced (17.3 ± 2.7% vs. 112.8 ± 3.1%, P < 0.001 and 11.8 ± 4.7% vs. 119.1 ± 4.6%, P < 0.001, respectively) and the mean BCVA improved (5.11 ± 1.35 vs. 0.83 ± 1.03 letters, P = 0.014) in the study eyes compared to those in the control eyes. Development of parafoveal iRORA (nGA) (67%, 12 of 18 eyes) and cRORA (GA) (22%, 4 of 18 eyes) was observed in the study eyes, whereas three cases of iRORA and cRORA in the control eyes (17%, 3 of 18 eyes; P = 0.010 and P = 0.791, respectively). CONCLUSIONS: Laser and anti-VEGF treatment may be a potential treatment option for intermediate AMD with dPED. However, considering the relatively high rate of secondary iRORA and cRORA development, long-term follow-up is mandatory to clarify the safety and efficacy of this treatment.
