Medical Background

Diabetes mellitus is a chronic systemic disease, characterized by increased levels of glucose. It can be divided into two main types: Type 1 (always insulin dependent) and Type 2 (usually non-insulin dependent). It is caused principally by pancreatic failure in type 1 diabetes and mix of pancreatic insufficiency and peripheral insulin resistance in type 2. Retinopathy is a term commonly used to refer to non-inflammatory damage to the retina of the eye, particularly secondary to a malfunction of the retinal blood vessels. Retinopathy can frequently be a sign of systemic disease. Retinopathy secondary to diabetes i.e. diabetic retinopathy is unfortunately a common complication of diabetes mellitus, which can eventually lead to blindness especially when blood glucose levels are uncontrolled. It is characterized by varying degree of damage to the retinal vessel networks, lying on the surface of the retina. The retinal vessel network is the uniquely easily visible in vivo and viewing the retina is a common clinical procedure which is useful in the diagnosis of hypertension, diabetes and several other diseases.


The clinical features of diabetic retinopathy, taken from http://www.eyemdlink.com/pop/eyeAnatomy.htm

All people with diabetes mellitus are at a degree risk of developing diabetic retinopathy over time. Persistently high levels of blood glucose may damage the circulatory system which can lead to a series of complications including kidney failure and cardiac disorders.
