optomap Imaging and Diabetes

Each year, November 14th is recognized as World Diabetes Day and this year’s theme is “Education to Protect Tomorrow”. Understanding the condition is the first step towards managing and preventing it. One in 10 adults around the world currently live with diabetes, an estimated 537 million people. Almost half do not know they have it.

Diabetes can affect your eyes in many ways. Some people go on to develop an eye complication called diabetic retinopathy (DR), glaucoma, diabetic macular edema and cataracts. DR is often reported as the most common form of diabetic eye disease. It is a serious complication of diabetes mellitus (DM), affecting one third of all people with the disease, and it is in most countries, the leading cause of blindness among the working-age adults. Everyone with diabetes is at risk of losing vision, this is a frightening fact. Losing your sight could affect your career, your family life and your independence but fortunately early diagnoses and timely treatment of diabetic retinopathy can prevent sight impairments and blindness.

Over 40% of patients diagnosed with diabetes eventually develop some level of diabetic retinopathy. Diabetic retinopathy is the leading cause of vision loss in working-age adults (20-65 years).  Approximately one in three people with diabetes have diabetic retinopathy and one in ten will develop a vision threatening form of the disease. DR occurs as a direct result of chronic hyperglycemia (high glucose) causing damage to the tiny blood vessels of the retina, the light-sensitive tissue that lines the back of the eyes. In the less severe form of DR, blood vessels swell and leak small amounts of blood and fluid into the eye. Vision may be unaffected, giving no clue to the presence of disease. Untreated, this mild form of DR can progress leading to macular ischemia, in which capillaries in the macula close and cause blurred vision. More advanced DR causes macular edema, which results in the swelling of the macula leading to the potential of complete vision loss.  

Managing diabetes goes a long way to managing diabetic retinopathy. Diabetes management includes controlling blood pressure, blood glucose and lipid levels. This can be achieved by encouraging a healthy lifestyle and medication as required. Improved control can slow the progression of eye disease, especially when initiated soon after diabetes is diagnosed.

Diabetic retinopathy may have no outward signs but can quickly progress to complete vision loss. Doctors will often recommend those with type 1 or 2 diabetes undergo a comprehensive eye exam once a year, or even more often if there are signs of DR.

optomap® imaging has been shown to improve management of diabetes in patients. optomap images capture a 200° view (about 82%) of the retina versus the 75° view provided by 7SF images. Studies have shown that this wider view can uncover evidence of disease that’s outside the narrow view of 7SF images. It can even change how doctors judge the severity of disease. In addition, the latest study identified that 50% of the lesions were in the area outside of ETDRS and that in 13% of patients these lesions suggested a more severe grade of retinopathy.

Evidence of disease at the periphery of the retina can also be a sign of future problems. Patients with peripheral DR lesions were more than four times more likely to see their DR get worse as compared to patients without lesions.

Diabetic retinopathy can impact people of all ages and in cases of diabetic eye diseases and further complications, early detection is key. optomap can help doctors to better monitor and facilitate decision making regarding treatment. For practitioners who are looking for the ability to assess their patient base quickly and efficiently, for signs of Diabetic Retinopathy (DR), Optos AI for DR Optos AI for DR combines the powers of ultra-widefield retinal imaging with AI assessment in a cloud-based platform, closing the vision care gap.
