is a disease in which, among other changes, there is an increase of "sugar" in the blood.
This disruption can damage several areas of the body. The eyes are one of the organs that can be severely affected
although initially there are no major symptoms. Diabetic retinopathy
is an ocular manifestation of the disease and is one of the leading causes of blindness.
To prevent blindness
, blood sugar levels (blood glucose) should be monitored as closely as possible
from the earliest stages of the disease.
arises as a result of changes in the small blood vessels
of the retina inside the eye. The altered vessels let fluid and blood flow to the retina leading to decreased vision. In some cases abnormal vessels develop in the retina
. These vessels are very fragile and bleed easily also leading to the formation of fibrous tissue that pulls back the retina. This stage of the disease is very serious and is called proliferative diabetic retinopathy.
