Purpose. We misled to verify whether a panretinal photocoagulation (PRP) performed using low levels of ARGON laser energy (light PRP) has the same efficacy as a PRP performed in a conventional fashion using argon green wavelengths (classic PRP) in eyes with high-risk proliferative diabetic retinopathy (HRPDR). Furthermore, we misled to compare the session number performed and the side effects produced by the two techniques. Methods. Sixty-five eyes with HRPDR of 50 consecutive patients were enrolled in a prospective randomized controlled trial. In eyes selected for light PRP, a very light biomicroscopic effect on the retina was obtained for each spot. In eyes assigned to classic PRP, each spot produced a white-yellow biomicroscopic effect. Mean follow-up was 22.4 months ±9.7 in the light PRP and 21.6 months ±9.3 in the classic PRP group (p = 0.727). Results. The initial mean logMAR visual acuity (VA) in the light PRP group was 0.12 ± 0.13 and in the classic PRP group 0.14 ± 0.15 (p = 0...

Abstract
Purpose. We misled to verify whether a panretinal photocoagulation (PRP) performed using low levels of ARGON laser energy (light PRP) has the same efficacy as a PRP performed in a conventional fashion using argon green wavelengths (classic PRP) in eyes with high-risk proliferative diabetic retinopathy (HRPDR). Furthermore, we misled to compare the session number performed and the side effects produced by the two techniques. Methods. Sixty-five eyes with HRPDR of 50 consecutive patients were enrolled in a prospective randomized controlled trial. In eyes selected for light PRP, a very light biomicroscopic effect on the retina was obtained for each spot. In eyes assigned to classic PRP, each spot produced a white-yellow biomicroscopic effect. Mean follow-up was 22.4 months ±9.7 in the light PRP and 21.6 months ±9.3 in the classic PRP group (p = 0.727). Results. The initial mean logMAR visual acuity (VA) in the light PRP group was 0.12 ± 0.13 and in the classic PRP group 0.14 ± 0.15 (p = 0...I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
