Diabetes is a life-long condition which can affect your blood sugar levels, by causing them to be too low or too high. However, it also has a significant impact upon eye health, and is actually one of the most common causes of sight loss among people of working age. To commemorate World Diabetes Day 2015, we explore the symptoms of diabetes and the effects of diabetic retinopathy, and we share our tips for good eye health with you.
Diabetes is a common condition, and there are two different types. In Type 1 diabetes, the body’s immune system attacks and destroys the cells that produce insulin. Type 2 diabetes causes the body to not produce enough insulin, or results in the the body’s cells not reacting to insulin. Type 1 diabetes develops rapidly, whereas Type 2 has a gradual progression over time and is therefore not always easily detected. It is important for people with diabetes to be able to control their own blood sugar levels through diet and insulin, to manage and prevent symptoms.

This article explains the symptoms of and treatment for the diabetic eye, which is also known as diabetic retinopathy.
What is Diabetic Retinopathy?
Diabetic retinopathy is a common complication of diabetes which is caused by high blood sugar levels damaging the cells of the retina over time. This can lead to blood vessels within the retinal becoming leaky or growing erratically, which can prevent light being detected by the retina. If left untreated, diabetic retinopathy can result in loss of sight or even blindness.
The initial stages of diabetic retinopathy are not personally noticeable, but by the time symptoms begin to appear permanent damage may have already have been done to the delicate tissues of the the eyes. Therefore regular monitoring by a qualified ophthalmologist is absolutely essential for anyone who may be susceptible to diabetic retinopathy.
The treatment of diabetic retinopathy is dependent upon the stage of the condition. In it’s early stages, more severe disease can be prevent by improved control of your diabetes. However, more advanced retinopathy can require laser surgery or injection treatment to prevent further problems. Prevention is definitely better than cure in this scenario.
