Ultra-wide-field imaging in diabetic retinopathy; an overview

Purpose: To present an overview on ultra-wide-field imaging in diabetic retinopathy. Methods: A comprehensive search of the pubmed database was performed using the search terms of "ultra-wide-field imaging ", "ultra-wide-field fluorescein angiography" and "diabetic retinopathy ". The relevant original articles were reviewed. Results: New advances in ultra-wide-field imaging allow for precise measurements of the peripheral retinal lesions. A consistent finding amongst these articles was that ultra-wide-field imaging improved detection of peripheral lesion. There was discordance among the studies, however, on the correlation between peripheral diabetic lesions and diabetic macular edema. Conclusions: Visualization of the peripheral retina using ultra-wide-field imaging improves diagnosis and classification of diabetic retinopathy. Additional studies are needed to better define the association of peripheral diabetic lesions with diabetic macular edema. Copyright (c) 2016, Iranian Society of Ophthalmology.
