Official Title: Three Arm, Prospective, Single-blind, Randomized Study Comparing Ranibizumab Plus Green Diode Laser Versus Ranibizumab Plus Pattern Scan Laser (Pascal) Versus Ranibizumab (Monotherapy) for Proliferati
Brief Summary:
Objectives:
Primary objective:
To evaluate the effects on retinal morphophysiology of full scatter single target panretinal photocoagulation (PRP) versus full scatter multiple target panretinal photocoagulation (both combined with intravitreous injections of ranibizumab) versus intravitreous ranibizumab (IVR) alone in patients with proliferative diabetic retinopathy (PDR).
Primary outcome:
The primary endpoint for this study is the mean change in the total area of active retinal neovessels, as measured by fluorescein angiography leakage area, in mm2, from baseline to week 48.
Secondary objectives:
Strategic goal:
In the era of anti-VEGF treatment for retinal neovascularization 1, 2, 3, 4 , it is time to determine what would be the best association of PRP + anti-VEGF for proliferative diabetic retinopathy (PDR), or still, if just intravitreal anti-VEGF treatment would be even better regarding morphologic (new vessels area and CSFT) and functional parameters (BCVA, ERG response and visual field).
