What are diabetic symptoms of retinopathy?
Diabetic retinopathy is a potential complication of type 1 diabetes and type 2. People with diabetes are most at risk of this eye if their blood sugar levels are not well controlled because chronically high levels of blood sugar promote inflammation. Blood vessels in the eyes are particularly vulnerable to this inflammation due to their small size and fineness. Diabetic symptoms of retinopathy may include blurred vision and black, floating spots in the field of view. If the condition proceeds, partial or full blindness may occur. The retina is a thin tissue layer located in the back of the eye and is a focus in which the images entering the eye are accepted and transmitted to the brain. Retinal damage can prevent the reception and transmission of images, leading to loss of vision and blindness. The main factor causing retinal damage is inflammation that is directly caused by high blood sugar levels but another factOry concerning blood sugar can lead to diabetic retinopathy. For example, abnormally high sugar levels in cells can cause abnormal protein reactions that can negatively affect many aspects of cellular function.
diabetic retinopathy develops in two stages, each with slightly different symptoms of diabetic retinopathy. The first stage is called Nondeliferative diabetic retinopathy and the second is called proliferative retinopathy. Undefined diabetic retinopathy can be further divided into mild, medium and serious categories based on the severity of the eye damage.
non -transparent diabetic retinopathy develops when chronic high blood sugar leads to inflammation of blood vessels and microaneurysms. These are small areas of swelling in the blood vessels of the retina. As the disease progresses into a mild stage, the blood vessels of the retina are blocked, and in a heavy stage are gradually BLmore vascular. Diabetic retinopathy symptoms are not always present at the Nondeliferative Stage. When they appear, the symptoms are usually limited to blurred vision and the occasional presence of floating black spots in the field of view.
In proliferative retinopathy, new blood vessels grow in retina in an effort to repair damage. This new vessel does not cause any symptoms, but are fragile and prone to breaking. If these blood vessels break, other symptoms of diabetic retinopathy may develop. Broken containers can escape blood and can cause serious loss of vision or even blindness.
Symptoms of retinopathy takes many years to develop, as the early stages of the disease are asymptomatic damage. Symptoms sometimes do not appear until irreparable damage is caused on the retina, causing loss of vision that cannot be restored. For this reason, people with diabetes are called to undergo annual eye control to help maintain health and vision of eyes.
