Diabetes tends to weaken the immune system of the body and make it prone to numerous diseases including eye illnesses. According to research, Diabetes is one of the leading causes of blindness in adults between the ages of 20 – 75.
What really happens?
Diabetes is a condition of increased blood sugar levels that also affects the eyesight. It causes a swelling in the lens of the eye that poses an obstacle to your vision. Controlling blood sugar levels is a must in order to secure your sight and a stable diet and lifestyle changes might be able to bring the sight back to normal within a couple of months. Some of the eye diseases one is vulnerable to especially as a diabetic involves blurred vision, glaucoma, cataract and diabetic retinopathy.
The cloudiness seen over a lens is proof of the existence of a cataract. An eye that has a cataract will constantly see blurry images; it will feel as though one is looking at the world through a foggy screen. In fact every illustration appears less colourful, and everything seems hazy. The ideal solution to protect your sight is to get a laser cataract surgery done.
The longer people have diabetes, the more the risk for glaucoma. The risk for glaucoma increases with age. Glaucoma may have no warning symptoms. If ignored, it can lead to blindness; occasionally patients may have
- Excessive Irritation and Watering
- Blurring (TUNNEL PICS)
- Rainbows around lights at night (Glare)
- Cloudy Vision
- Recurrent Redness
- Headaches with or without Vomiting
The eye nerve is responsible for transferring visual information to the brain.Diabetic retinopathy is the umbrella term for all the problems of the retina caused by diabetes. The growth of new abnormal blood cells on the surface of the retina can damage the retina. The types of retinopathy are:-
Non-proliferative:-This is the early stage of the disease. Small blood vessels start to bulge causing blood vessel blockage and loss of blood supply.
Proliferative diabetic retinopathy:-An advanced stage of diabetic retinopathy in which the blood vessels start to leak and severely blur vision. This bleeding causes dark spots and clouded vision & abnormal blood vessels block the flow of blood to the nerves.
The key risk factors for Retinopathy are Poor Blood sugar control, Duration of diabetes, High blood pressure, High Cholesterol.
It is not always possible to prevent diabetic retinopathy. Nevertheless, regular eye check-ups, good control of your blood sugar and blood pressure, and early intervention for vision problems can help prevent severe vision loss.
