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,

Dr. Lewis Eye Care has made the difficult choice to temporarily close due to the COVID-19 virus pandemic based on the recommendation of the CDC. We cannot perform eye exams while maintaining social distancing, so continuing to see patients at this time could contribute to the spread of the virus.

Our initial plan had been to reopen Monday April 6th. However, as we get closer to that date it is becoming apparent that we may have to be closed for a longer, indefinite period of time.

If you are having an urgent eye health issue, there are some clinics in our area that are seeing patients for emergencies during shorter business hours. You should call ahead to those offices before going to their clinic, as their availability might change day by day. Those clinics could include Vancouver Eye Care at 360-823-2020, Peace Health Medical Group Eye Care at 360-514-7210, and Vancouver Clinic in Salmon Creek at 360-882-2778.

If you need a glasses or contact lens prescription emailed to you from our office, click on the Contact Form link, type in your name, email, and what you are requesting, and we will email you the information you need as soon as we can.

Thank you for your understanding, and please stay healthy during this difficult time.

Sincerely,

Dr. Scott Lewis, OD
