This article topic is – Diabetic Eye Disease Stages! Even though Diabetes can affect all the organs in the body, the eye is at increased risk. The retina consumes oxygen and blood glucose at higher rates than any other tissue in the body.
As these substances are supplied by the circulatory system, any disorder that interferes with the blood supply can do severe damage to the retina.
The Diabetic Eye Disease also known as the Diabetic Retinopathy is a condition caused by damage to the blood vessels of the retina due to diabetes. The various stages of diabetes retinopathy are described below:
Nonproliferative Diabetic Retinopathy (NPDR):
This is the earliest form of diabetic retinopathy. Normally, the blood vessels in the retina do not leak, the retinal blood vessels can develop tiny leaks, which then cause fluid or blood to seep into the retina.
The retina becomes edematous (wet & swollen) and can’t function properly. This is called nonproliferative diabetic retinopathy.

Proliferative Diabetic Retinopathy (PDR):
This is more advanced and serious from of diabetic retinopathy in which the diseased retina blood vessels can close, cutting off nutrition to the retina.
This mechanism stimulates the formation of new immature vessels. These new vessels are weak and are easily ruptured causing heavy bleeding inside the eye.

When fluid leaks in the macular area, causing swelling in the macula, the condition is called Macular Edema. Since the prime function of the macula is central visual acuity, people with maculopathy complain loss of central vision.
Complications of Diabetic Retinopathy:
The visual problem caused by diabetes does not end with NPDR or PDR. There are two major sight threatening complications.
The new blood vessels can bleed into the vitreous cavity, a condition called vitreous hemorrhage. It results in a sudden and total loss of vision, which may take months to resolve and may even require surgery.
The second problem is the growth of the scar tissue on the retina of the wall of the eye. This condition is called fractional retinal detachment and cause a sudden drop in vision that requires immediate surgical intervention.
