According to an article written by Paul E. Tornambe, MD, FACS and appearing in the April 2015 issue of Retina Today, Optos’ ultra-widefield (UWF™) retinal imaging is helping manage and advance knowledge in diabetic retinopathy (DR). In fact, Tornambe can be quoted as saying UWF retinal imaging “…will facilitate earlier diagnosis, more accurate evaluation and better treatment outcomes.”
How UWF is Improving Diagnosis
Several studies have been conducted and indicate that UWF imaging has the potential to improve diagnosis and management of DR. In the article, Tornambe references several studies that show, compared to standard technology, optomap® provides high resolution images that allow for a much larger view into the periphery of the retina (200 degrees), the images are acquired rapidly and often, the patients’ eyes do not have to be dilated. Not only are the images much higher quality, it stands to reason patients are more likely to maintain a proper diagnostic schedule if they do not have to undergo dilation.
With multiple modalities such as fluorescein angiography and red-free color imaging, Optos UWF technology consistently reveals more pathology if present than other diagnostic tools are able, leading to earlier diagnosis in some cases and more advanced disease progression in others who were previously diagnosed with DR.
UWF’s Contribution to DR Management
While a number of results have already been published as evidenced by the article, there are still active studies being performed to determine the effect of UWF retinal imaging on prognosis for patients with DR. To date, strong correlations between peripheral retinal ischemia and diabetic macular edema have been formed, allowing earlier diagnosis and targeted treatment options to mitigate vision loss. Findings have also indicated additional treatment to prevent postvitrectomy diabetic vitreous hemorrhage, a basis for creating an ischemic index to determine the severity of DME and several other insights that are contributing to improving patient care.
