The Effects of Diabetic Eye Disease, Dr. Snider – Elite Eye Care, Vancouver, Diabetes, glasses, eye care WA

A person with diabetes suffers from higher than healthy blood sugar levels as a result of the body’s inability either to produce a sufficient amount of insulin or properly absorb the insulin being produced. Unfortunately, beyond the high blood sugar that is a direct result of diabetes, many
complications arise as an indirect result of diabetes, particularly when it comes to a person’s eyes.

Nonproliferative diabetic retinopathy is the earliest stage of retinopathy. This occurs when damaged blood vessels in the retina begin leaking fluids and blood into the eye. In some cases, deposits of cholesterol from the blood may leak into the retina. Although diabetic retinopathy at this stage is rarely sight threatening, sometimes swelling or thickening of the macula caused by fluid leaked into the eye causes the macula to function improperly. This is called macular edema and is the leading cause of vision loss caused by diabetes.

Dr. Snider of Elite Eye Care in Vancouver explains, “Diabetic retinopathy is possibly the most serious eye condition related to diabetes. This occurs as a result of extended periods of high blood sugar. Diabetic retinopathy comes in two types: nonproliferative and proliferative.”, Dr. Snider, Vancouver eye doctor.

Proliferative diabetic retinopathy is a more advanced stage of retinopathy in which many blood vessels in the eye have closed themselves off, preventing proper blood flow to the eyes. As a result, the retina begins to grow new blood vessels to attempt to make up for blood not being carried to the eyes through the now closed blood vessels. These new blood vessels are abnormal, however, and are not able to supply the retina with proper blood flow. At the same time, the new blood vessels often create scar tissue that may cause the retina to wrinkle or detach. Proliferative diabetic retinopathy is generally more serious and sight threatening than non-proliferative retinopathy because of the possibility of very serious complications such as traction retinal detachment, in which the wrinkling of the retina
causes distortions in vision and may become very severe if large parts of the macula or retina become detached.

People with diabetes are also at significantly increased risk of developing cataracts, a clouding of the vision caused by clumps of protein forming in the lens of the eye. Although cataracts usually affect people in their elderly years, diabetics tend to develop cataracts at a younger age, and their condition progresses much faster. In cataracts that cause significant blockage of the lens, the lens must be removed and replaced by an artificial lens in order to restore vision. This is not without risks, however. Studies have shown that a person’s retinopathy can worsen and glaucoma may start to develop as a result of removing and replacing the lens.

In reference to another serious condition resulting from diabetes, Dr. Snider comments, “People with diabetes are at a 40% higher risk for contracting glaucoma, and this risk increases as a person ages. This condition occurs when fluid pressure inside the eye builds up and damages the optical nerve. With glaucoma, damage is done slowly, and a person may not realize they are losing their vision until significant damage has been done.”

It is important to have regular eye exams to monitor for warning signs of these and other conditions that result from diabetes.
