Building upon two previous studies regarding the use of optomap images for studying diabetic retinopathy (DR) where optomap was found to be equivalent to Early Treatment Diabetic Retinopathy Study (ETDRS)1, and where there was the presence of predominantly peripheral lesions, they were associated with an almost 5-fold risk in the progression of DR over 4 years2, a recent study from the American Academy of Ophthalmology concludes that there is a good to excellent agreement between ultra-widefield (UWF™) images and ETDRS standard photos in determining H/Ma (hemorrhage/microaneurysm) severity, with excellent correlation of H/Ma counts within ETDRS photo fields. Utilizing the full capability of UWF peripheral fields however, produced identification of 49.8% more H/Ma suggesting a more severe H/Ma in 12.7% of eyes.
Retinal hemorrhage and/or H/Ma are critical clinical signs of early DR; similarly, the presence and severity of H/Ma are considered reliable markers for the level and risk of progression in DR. Ma (microaneurysm) counts and level also may indicate critical progression of proliferative DR and macular edema.
The objective of the study was to evaluate detection of H/Ma and/or hemorrhage comparing the two aforementioned modalities. When first evaluating a similar retinal scope of the two modalities, both UWF …
