Peripheral Lesions Identified on Ultrawide Field Imaging Predict Increased Risk of Diabetic Retinopathy Progression over 4 Years
optomap imaging has demonstrated that diabetic lesions occur in the retinal periphery in up to 50% of eyes and these lesions might result in a more severe grade of retinopathy in 10% of eyes. Eyes with predominantly peripheral lesions (defined as outside of ETDRS 7 standard field) had a 4.7 fold increased risk of progression to proliferative diabetic retinopathy (PDR). Eyes with predominantly peripheral lesions had a 3.2 fold risk of 2 step progression in DR.
CSS - Defining UWF
“A single capture image which provides a view of the vortex veins in all four quadrants and beyond, thus meeting the widefield & ultra-widefield definitions, would offer enhanced efficiency in a real-world clinical setting versus a montage image, whether it be manual or automated.”

optomap Ultra-widefield Advances
The development of ultra-widefield retinal imaging has accelerated our understanding of common retinal diseases. As we continue to validate the diagnostic and prognostic significance of pathology in the retinal periphery, the ability to visualize and evaluate these features in an efficient and patient-friendly manner will become more important. Current interest in ultra-widefield imaging includes the development of potential biomarkers of disease progression and indicators of preclinical disease development.
Comparing diabetic retinopathy lesions in scanning laser ophthalmoscopy and colour fundus photography
There was good correlation in detected microaneurysms, blot haemorrhages and cotton wool spots between SLO and colour fundus photographs. However, there was intergrader variability in flame haemorrhage, intraretinal microvascular abnormalities, venous beading and neovascularization grading with both modalities.
A Review of Clinical Applications and Future Trends
Optos ultra-widefield imaging has become an essential tool for the identification of peripheral retinal and vascular pathology. The high resolution and multimodal capabilities of this device are also providing new insights into a variety of disorders, even those that primarily involve the posterior pole.
