Causes of Diabetic Retinopathy

What are the causes of diabetic retinopathy and long-term diabetes? Changes in blood-sugar levels is the main culprit. People suffering from diabetes generally develop diabetic retinopathy after at least ten years of having the disease. Once you are diagnosed with diabetes, it is essential to have an eye exam once a year or more.

In the early stage of diabetic retinopathy, called background or non-proliferative retinopathy, high blood sugar in the retina damages blood vessels, which bleed or leak fluid. This leaking or bleeding causes swelling in the retina, which forms deposits.

In the later stage of diabetic retinopathy, called proliferative retinopathy, new blood vessels begin to grow on the retinal. These new blood vessels may break, causing bleeding into the vitreous, which is the clear gelatinous matter that fills the inside of the eye. This breakage can cause serious vision difficulties. This form of diabetic retinopathy can cause blindness, and is therefore the more serious form of the disease.

It is not hard to greatly reduce your risk of diabetic retinopathy by following some simple steps and being aware of your overall health. The most important factor you can control is maintaining your blood sugar at a healthy level. Eating a healthy diet will help greatly in controlling blood sugar levels. A regular exercise regimen is also a great help. Finally, make sure to listen to your doctor’s instructions.

The pandemic of coronavirus (COVID 19) continues to spread endangering many of us who call Midland/Odessa home. While the number of cases in Texas is growing rapidly, so far there are few cases in our area. At Vision Health Specialties it is our goal to keep it that way.

Because eye care by necessity requires close contact between workers and patients, the Center for Disease Control along with other eye care specialty organizations recommend that during this critical period eye doctors suspend routine vision examinations. In complying with this, Vision Health Specialties will terminate routine eye care beginning Monday, March 23‎rd until Monday, April 20th. We will be open from 9:00 till 4:00 PM during this period of time with a small staff to handle urgencies such as red eyes, corneal ulcers, uveitis, abrasions, sudden increases in floaters, or flashes, and foreign bodies in the eye. Please call our office before coming in. Furthermore, those who have traveled to China, Italy, South Korea, Japan, Iran, or the state of Washington, California, New York, Louisiana and/or other affected areas, as well as those who have respiratory disease, and/or fever, will be referred to the emergency department of Midland Memorial Hospital where they are equipped to handle those at risk of coronavirus.
