can be a complication of diabetes type 1
or diabetes type 2.
Initially DR is asymptomatic , if not treated
though it can cause low vision or blindness.
20 years of diabetes ,nearly 99% of
patients of type 1 diabetes and 60%of type 2

signal the need for new blood vessels
retina sends signals so new blood vessels
are created . These blood vessels are
abnormal and more likely to hemorrhage due
to the thin walls of the blood vessels . The

The best measure for
prevention of loss of vision
from diabetic retinopathy
is strict glycemic control
Dr threatens vision treatment can
include:Laser therapy to seal leaking blood
vessels (focal laser)
Laser therapy to reduce retinal oxygen
demand (scatter laser)
Surgical removal of blood from the eye
