“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 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 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.
Comparison of ultra-widefield fluorescein angiography with the Heidelberg Spectralis® noncontact ultra-widefield module versus the Optos® optomap®
On a single nonsteered image, the Optos optomap covered a significantly larger total retinal surface area, with greater image variability, than did the Heidelberg Spectralis ultra-widefield module. The Optos captured an appreciably wider view of the retina temporally and nasally.
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 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.
Non-contact ultra-widefield imaging of retinopathy of prematurity using the Optos dual wavelength scanning laser ophthalmoscope.
The Optos ultra-widefield scanning laser ophthalmoscope is capable of acquiring clinically useful high-quality images of the fundus in ROP subjects. The imaging technique could potentially be used in monitoring ROP progression and documenting ROP regression following treatment.
optomap Helpful in Telemedicine Program
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.
Peripheral Changes Found in 97% of Patients with AMD Imaged with optomap in the Reykjavik and OPERA studies
Phenotyping the retinal periphery using the categories defined by the International Classification confirmed the presence of wide-ranging AMD-like pathologic changes (97%) even in those without central sight-threatening macular disease. Based on our observations, we propose here new, reliably identifiable grading categories that may be more suited for population-based UWFI.
