Diabetic Retinopathy

What is Diabetic Retinopathy?

Diabetic retinopathy is a complication of diabetes that damages the blood vessels in
the retina (the light - sensitive tissue at the back of the eye). This can lead to vision problems and even blindness if left untreated

Causes and Risk Factors

High blood sugar levels, high blood pressure, and high cholesterol can damage the blood vessels in your retina. The longer you have diabetes, the higher your risk of developing diabetic retinopathy.

Symptoms

In the early stages, diabetic retinopathy often has no symptoms. That's why regular eye exams are crucial. As the condition progresses, you may experience:

• Blurred vision
• Floaters (dark spots)
• Flashes of light
• Vision loss

Screening and Timing

The American Diabetes Association recommends:

Type 1 diabetes: Get an eye exam 5 years after diagnosis
Type 2 diabetes: Get an eye exam at diagnosis
Pregnant women with diabetes: Get an eye exam during the first trimester

Screening Technique

A comprehensive eye exam includes:

• Visual acuity test
• Dilated eye exam (where your pupils are widened with eye drops)
• Retinal imaging (photographs of the retina)

Treatment Options

If diabetic retinopathy is detected, treatment can prevent vision loss.

Options include:
Laser photocoagulation: A procedure that uses a laser to destroy abnormal blood vessels.
Anti - vascular endothelial growth factor (anti - VEGF) injections: Medications that help stop the growth of abnormal blood vessels.
Vitrectomy: Surgery to remove blood and scar tissue from the eye.

Good News

With regular eye exams and proper treatment, you can prevent vision loss and protect your eyes. Controlling your blood sugar levels, blood pressure, and cholesterol can also slow disease progression.

What Can You Do?

1. Schedule regular eye exams
2. Manage your diabetes, blood pressure, and cholesterol
3. Report any vision changes to your doctor

By staying proactive and working with your healthcare team, you can safeguard your vision and live a healthy life with diabetes.
