Brief Summary

The purpose of this study is to identify alterations of the blood-retinal barrier (BRB) in diabetic retinas using a novel non-invasive approach based on the Fourier domain high-definition optical coherence tomograph (OCT).

Detailed Description

Type 2 diabetic patients with nonproliferative diabetic retinopathy (NPDR) (study population) and healthy volunteers (control population).

Inclusion Criteria:

Age over 18 years; type-2 diabetes; NPDR levels 10, 20 and 35/47 (ETDRS severity scale); and an area of retinal leakage of at least 25% of the RLA map (macular area).

Exclusion Criteria:

Presence of media opacity; vitreous syneresis or posterior vitreous detachment, and; previous photocoagulation treatments or any type of intraocular surgery or intravitreal medications; and other retinal pathologies.

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Optical reflectivity as measured by optical coherence tomography	To analyse OCT reflectivity distribution between areas with and without fluorescein leakage in type 2 diabetic eyes. In previous studies our group found differences, when comparing the histograms of the optical reflectivity distribution, suggesting that the optical reflectivity, as measured by OCT, may change under BRB alterations	14 months
