Diabetic Retinal Photography
Diabetic retinal photography is a screening test which helps prevent blindness caused by diabetic retinopathy, an eye disease common among diabetic patients.
Diabetic retinopathy is a leading cause of blindness in Singapore. It occurs when high blood sugar cause damage to the blood vessels of the light-sensitive tissue at the back of the eyes (retina). The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this condition.
In the early stage, diabetic retinopathy may show no symptoms or only cause mild vision problems. Eventually it can cause blindness.
Some symptoms are:
Spots or dark strings floating in your vision (floaters)
- Impaired color vision
Dark or empty area in your vision
Foot problems are common causes of chronic disabilities in patients with diabetes.
Neuropathy (a type of nerve damage, typically causing numbness or weakness) is common in diabetic patients. It occurs because high blood sugar damages the nerve fibres in their bodies. Foot injuries can go undetected when the legs and feet are numb due to neuropathy.
Early identification and intervention of those at risk, will prevent complications and reduce the need for amputations.
Diabetic retinal photography and foot screening are recommended to be done annually.
