optomap Equivalent to ETDRS
Results from a large multi-center collaborative study confirm the equivalence of optomap to ETDRS Gold Standard for grading diabetic retinopathy.
Peripheral Lesions Identified on Ultra-wideField Imaging Predict Increased Risk of Diabetic Retinopathy Progression over 4 Years - Updated 2020
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.
Defining UWF
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.
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.
optomap Used to Guide OCT to the Far Periphery
A study published in Ophthalmology describes how ultra-widefield (UWF) optomap can be used to guide SD-OCT to image retinal features in the mid-far periphery.
optomap shows more vortex vein ampullae than previously reported (ORPHEE2)
To study the number and distribution of vortex ampullae in healthy eyes using ultra-wide field (UWF) indocyanine green angiography (ICGA).
optomap Assisted Ophthalmoscopy Improves Sensitivity of BIO Exam by 30%
Image-assisted fundus examination may enhance detection of retinal lesions by up to 30% compared with traditional fundus examination alone.
optomap Helpful in Telemedicine Programs
Several studies published in Diabetes Care have found that optomap detected 17% more diabetic retinopathy and was more efficient than traditional non-mydriatic fundus imaging.
Feasibility and clinical utility of ultra-widefield indocyanine green angiography.
optomap icg images were comparable in the central pole to standard imaging devices and peripheral changes were visualized outside of 60° field of view in 67% of eyes.
