Diabetics in GCC should get their eyes screened for diabetic eye condition
Patients suffer from diabetic retinopathy due to poor diabetes management and failure to seek regular eye check-ups

According to Dr. Raeba Mathew, HOD, Specialist Ophthalmologist, Canadian Specialist Hospital, Dubai, "The main reasons diabetics suffer from visual impairment is poor management of the condition and failure to seek an eye check-up. For diabetic patients an eye check-up is just as important as checking the blood sugar levels while the patients don't seem to be aware of that".
Diabetic retinopathy is a condition where high blood sugar levels damage the retina, the nerve layer lining the innermost part of the back of the eye. It can lead to vision impairment by leakage of the fluid into the central part of the retina, causing a gradual loss of central vision. It can also lead to sudden loss of vision due to the bleeding into the cavity of the eyeball, caused by rupture of small new blood vessels that grow in the retina because of diabetes where the patient may notice floating dots or even total loss of vision.
The detection of retinopathy can be done by retinal examinations followed by digital fluorescein angiography and a retinal scan. "Eye check-ups are not the top priority for diabetic patients who end up confusing them for the routine eye check-ups with the optometrist. But in fact, they are entirely different from each other and are covered by most insurance companies," added Dr. Mathew.
"Early diagnosis of the condition is very essential in the treatment of diabetic retinopathy. The first retinal examination should be done at initial diagnosis of Diabetes mellitus and thereafter every year. Patients, who have been diagnosed with retinopathy, may need to be seen more frequently. The incidence and severity of diabetic retinopathy depends on the duration and level of control of diabetes. Patients diagnosed with diabetes before the age of 30 years may have a higher chance of developing retinopathy,"
Once detected, the treatment of diabetic retinopathy is first and foremost by promoting better diabetes management in the patient, regularising follow-ups with doctor and monitoring the other aspects of diabetes including heart and kidneys. All stages of diabetic retinopathy do not require treatment for the eye. Depending on the severity of the retinopathy, the treatments available may be laser, injections or surgery.
