Diabetic Retinopathy Screening

What is Diabetic Retinopathy Screening ?

Diabetic Retinopathy is an eye condition caused by prolonged high blood sugar levels that damage the tiny blood vessels in the retina. It is one of the most common complications of diabetes and a leading cause of preventable blindness worldwide. Early detection and timely treatment through regular screening can help protect your vision and prevent serious complications.Many people with diabetic retinopathy experience no symptoms in the early stages. Vision changes may only occur when the disease has already progressed. Regular screening allows eye specialists to detect even the smallest changes in your retina, ensuring timely intervention.

Benefits of early screening

  • Detecting retinopathy before vision loss occurs

  • Reducing the risk of severe vision impairment

  • Guiding treatment such as laser therapy, injections, or surgery

  • Helping patients manage diabetes more effectively

Who Should Get Screened?

Diabetic retinopathy screening is recommended for:

  • All patients with Type 1 diabetes (starting 5 years after diagnosis)

  • All patients with Type 2 diabetes (starting at the time of diagnosis)

  • Pregnant women with diabetes (before conception and during pregnancy)

Regular follow-ups are advised every 6–12 months depending on your eye health and your doctor’s recommendations.

How is Diabetic Retinopathy Screening Done?

The screening process is simple, painless, and takes only a few minutes:

  1. Eye Dilation: Eye drops are used to widen the pupils.

  2. Retinal Photography/Imaging: A special camera captures detailed images of the retina.

  3. Examination by an Eye Specialist: The retina is checked for any signs of blood vessel damage, swelling, or leakage.

  4. Report & Recommendations: The results are explained, and follow-up tests or treatments are advised if needed.

Signs and Symptoms to Watch For

Although diabetic retinopathy often develops silently, consult your eye doctor immediately if you notice:

  • Blurred or fluctuating vision

  • Dark spots or floaters

  • Difficulty seeing at night

  • Faded or washed-out colors

  • Sudden vision loss

Treatment Options for Diabetic Retinopathy

If detected early, diabetic retinopathy can be managed effectively. Treatment options include:

  • Laser Treatment (Photocoagulation): Seals leaking blood vessels and prevents abnormal growth.

  • Intravitreal Injections: Medications are injected into the eye to reduce swelling and stop abnormal blood vessel formation.

  • Vitrectomy Surgery: Removes scar tissue and blood from the eye in advanced cases.

How to Prevent Diabetic Retinopathy

While screening is essential, prevention plays an equally important role. You can lower your risk by:

  • Controlling blood sugar, blood pressure, and cholesterol

  • Following a healthy diet and exercise routine

  • Quitting smoking and alcohol

  • Scheduling regular eye exams
