Diabetic Retinopathy

Diabetic Retinopathy

Diabetic Retinopathy diagnosis and treatment options in Boise, Idaho. People with diabetes mellitus (DM) can have abnormal sugar levels that in time can damage blood vessels in the retina, the tissue at the back of the eye that senses light and sends images to the brain. This blood vessel damage is referred to as Diabetic Retinopathy.
Vision affected by Diabetic Retinopathy

There are two types of Diabetic Retinopathy:

Nonproliferative Diabetic Retinopathy (NPDR) and Proliferative Diabetic Retinopathy (PDR).

NPDR is an early stage of Diabetic Retinopathy and results when tiny blood vessels within the retina leak blood or fluid. This can result in macular edema (swelling), macular ischemia which is the lack of normal blood flow, or both.

Proliferative Diabetic Retinopathy (PDR) is present when abnormal new vessels (neovascularization) begin growing on the surface of the retina or optic nerve. PDR may cause severe vision loss and can affect both central and peripheral vision.

These abnormal blood vessels are fragile and can bleed into the eye causing a vitreous hemorrhage. If mild, it may result in a few new dark floaters. A very large hemorrhage might block out all vision. Pulling and contracting of these abnormal vessels and their associated scar tissue can lead to a tractional retinal detachment where the retina is pulled away from the back of the eye leading to loss of vision.

Medical treatment may involve injections of medicine into the eye in order to decrease the edema of the macula, laser surgery to decrease fluid leakage or shrink abnormal new vessels, and vitrectomy, a surgical procedure to remove the blood-filled vitreous and abnormal vessels that caused the bleeding. If the retina is detached, it can be repaired during the vitrectomy surgery.

Early detection of Diabetic Retinopathy is the best protection against loss of vision. You can significantly lower your risk of vision loss by maintaining strict control of blood sugar, blood pressure, cholesterol, and weight control, and visiting your Boise, Idaho ophthalmologist regularly.
