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 Proliferative Diabetic Retinopathy.
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:

* To assess the mean changes in best corrected visual acuity (BCVA), the mean changes in central subfield foveal thickness (CSFT), the mean changes in wave B amplitude and oscillatory potentials on a full-field electroretinogram (ERG), and the mean changes on the peripheral visual field by static perimetry (30:2 strategy), from baseline to week 48.
* To assess the incidence of adverse events during the study.

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).

10. Medical or psychological conditions that would prevent the patient from giving informed consent and concluding the study
11. Significant uncontrolled diseases which, in the opinion of the investigator, would exclude the patient from the study

13. Untreated diabetes mellitus
14. Severe (blood pressure systolic \> 160 mmHg or diastolic \> 100 mmHg) AND untreated hypertension
15. Inability to comply with study or follow-up procedures.
16. Impaired or limited legal capacity
17. Participation in another clinical study in the last 30 days.
