A group of eye problems which can affect different people with diabetes is known to be the diabetic eye disease. Cataracts, Diabetic macular oedema, Glaucoma and Diabetic retinopathy are the conditions included. Diabetes for a long period of time can cause damage to your eyes. Over time diabetes can result in poor vision and can also lead a person to blindness.
How diabetes affects our eyes
When blood sugar or blood glucose is very high then diabetes affects our eyes. If the blood glucose level stays for a long amount of time then it can damage the tiny blood vessels situated in the back of our eyes. During the time of pre-diabetes or during the time when blood glucose level is a little higher than the normal then the damage can start. Swelling can take place because of the leaking of fluid due to damage blood vessels.
The retina is said to be the inner lining which is found on the back side of an eye. Brain decodes the light signals received by the retina. Blood vessels which are damaged can easily harm retina and can cause diabetic retinopathy.
Further with the damage of more blood vessels, diabetic retinopathy can move on to the next stage of danger level. This stage is termed as proliferative diabetic retinopathy. This can lead to a serious problem in vision.
Diabetic retinopathy takes place among one people out of three people. This one out of three people must have diabetes and his or her age must be 40 or more than that.
Common symptoms of Diabetic retinopathy
Some of the common symptoms of diabetic retinopathy include blurry vision, frequent changes of vision, a poor vision of colour, dark areas or loss of vision, flashes of light and dark strings or spots which are termed as floaters.
Liquid preventing diabetic retinopathy
Your eyes may be treated by anti-VEGF medicine like bevacizumab, aflibercept or ranibizumab. The main function of the medicine is to block the growth of blood vessels which shows abnormal characteristics. Anti-VEGF medicine is also capable of stopping the fluid leaks which can help in treating diabetic macular oedema.
During the office visits, the doctor will inject the anti-VEGF into the eyes. It may stop further loss of the vision and to some people, it can also improve vision. Vitrectomy and laser treatment are also applied to recover a patient from diabetic retinopathy.
