This diabetic disease occurs when a diabetic patient has an eye disease. The discomfort occurs when high blood glucose levels cause serious damage to the blood vessels in the retina. When this happens, the blood vessels swell and produce fluid leaks. Besides, the swelling can be closed and the blood does not flow.
On certain occasions, unusual blood vessels are produced in the retina. Changes can result in vision loss.
Diabetic eye discomfort consists of two main stages. The first non-proliferative diabetic retinopathy. It occurs early in the diabetic eye stage. Mostly diabetes patients suffer from it.
When you have NPDR, small ruddy vessels have losses and cause the retina to swell. The person with diabetes loses vision quickly.
Care must be taken that macular ischemia occurs, this occurs when the blood vessels in the retina close. This occurs when blood does not reach the macula. On certain occasions small particles form in the retina, known as exudates. When suffering from diabetic retinopathy, the vision becomes blurred.
Proliferative diabetic retinopathy, have an acceleration when the retina produces blood vessels. There the vessels fragment and bleed in the vitreous. If you see some flies in the air you might suffer from vitreous.
Blood vessels can cause scars. Proliferative diabetic retinopathy is very delicate and results in the loss of central and peripheral vision.
The human being may be suffering from retinopathy and not knowing it. The person in his initial stage cannot present symptoms. But when the disease increases, the symptoms may be stronger such as:
Large number of flies flying, difficulty seeing, vision changes from dark to light, seeing white or dark areas in the field of vision.
The view at night if it decreases, the colors are not appreciated with accuracy and loss of sight.
Signs of diabetic retinopathy usually affect both eyes.
