According to the university of Michigan
Kellog eye center, diabetic retinopathy can cause vision loss in two ways:
Kellog eye center, diabetic retinopathy can cause vision loss in two ways:
§ Macular
oedema
oedema
Macular oedema is a condition where the retinal blood
vessels develop tiny leaks. When this occurs, blood and fluid leak from the
retinal blood vessels and fatty material (called exudate) is deposited in the
retina. This causes swelling of the retina and is called diabetic macular
oedema. When this swelling occurs in the central part of the retina, also known
as the macula, vision is reduced or blurred.

§ Proliferative
retinopathy
retinopathy
Proliferative retinopathy refers to the
changes that occur when new, abnormal blood vessels begin to grow on the
surface of the retina. These abnormal blood vessels grow around the pupil,
glaucoma can result from the increasing pressure within the eye. These new
blood vessels have weaker walls and may break and bleed, or cause scarred tissues
to grow that the retina away from the back of the eye. When the retina is
pulled away it is called retinal detachment and if left untreated, it can cause
severe vision loss, including blindness. Leaking blood can cloud the vitreous
and block the light passing through the pupil to the retina, causing blurred
and distorted images.
