AS-OCT Study in Diabetic Retinopathy
Anterior Segment- Optical Coherence Tomography as Early Biomarker in Diabetic Retinopathy
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
To investigate the potential role of anterior segment-optical coherence tomography (AS-OCT) in identifying the corneal changes (in particular in total corneal, epithelial and stromal thicknesses) in patients affected by type 2 diabetes mellitus, without signs of diabetic retinopathy at fundus examination.
The AS-OCT could represents a valid early biomarker in these patients.
