Diabetic Retinopathy
What is it and how to Recognise it
It is the most important ocular complication of diabetes. It often manifests itself with impaired vision and discontinuity areas in the visual field, causing a “patchy vision” with loss of sharpness and sensitivity to light.
The main risk factors associated with the earlier appearance and faster evolution of DIABETIC RETINOPATHY are: the duration of diabetes, poor glycaemic control and any concomitant high blood pressure.
In the eye, this leads to a inadequate intake of oxygen in some areas of the retina, which consequently tend to become ischaemic. Before this degeneration process happens, new vessels proliferate in an uncontrolled way, damaging the retinal tissue.

Eye with Retinopathy
Diabetic retinopathy can be separated into two forms, based on the presence of newly formed vessels or otherwise:
- The proliferative more serious, form features intense vascular proliferation, with fragile vessels that tend to fracture, causing retinal damage;
- The non-proliferative form, characterised by microaneurysms (dilations of the vessels), which affect the small retinal vessels and the larger ones, sometimes involves accumulation of proteins, lipids and carbohydrates, which in turn tend to deteriorate the sight.
