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.

Dear Patients and Community

Local authorities have ordered a Stay Home order for most businesses in Houston/Harris county. We are currently operating from 10am-12pm for URGENT eye care visits (red eyes, infections, eye injuries, etc...), but no routine/wellness exams are being performed at this time. Furthermore, were are providing "Curbside" pickup of eyeglasses and contact lenses during those hours.

If contact lens wearers currently have less than three (3) months supply remaining, we highly recommend that they call to place an order now. Our doctors will approve up to an additional six (6) months supply. Furthermore, we will waive contact lenses shipping charges and ship directly to a home address at no charge.

With the day to day changes surrounding COVID19, we do not know how much longer our office will be open to the public. Due to this situation, we ask that any remaining glasses or contact lens supplies be picked up as soon as possible.

We thank you for your understanding and loyalty during this difficult time. Wishing you and you health and looking forward to serving you again soon.
