Diabetic Eye Screening

Diabetic eye screening is a comprehensive eye examination designed to detect and manage diabetic retinopathy, a common complication of diabetes that can lead to blindness if left untreated.

Purpose

The primary purpose of diabetic eye screening is to identify individuals with diabetic retinopathy, particularly those with sight-threatening disease, and provide timely treatment to prevent vision loss.

Who Should Undergo Diabetic Eye Screening?

• People with type 1 or type 2 diabetes
• Pregnant women with diabetes (gestational diabetes)
• Individuals with a family history of diabetic retinopathy
• Those who have had diabetes for an extended period

Screening Process

The diabetic eye screening process typically involves the following steps:

1. Visual Acuity Test: Measures the sharpness of vision using a standard eye chart.
2. Dilation: Eye drops are used to dilate the pupils, allowing for a more thorough examination of the retina.
3. Ophthalmoscopy: A specialized instrument called an ophthalmoscope is used to examine the retina and optic nerve for signs of damage or disease.
4. Retinal Photography: Digital images are taken of the retina to document any abnormalities and monitor changes over time.
5. Optical Coherence Tomography (OCT): A non-invasive imaging test that uses low-coherence interferometry to capture high-resolution images of the retina and its layers.

What to Expect During the Screening

During the screening, you may experience:

• Mild eye discomfort or blurred vision due to dilation
• Bright lights from the ophthalmoscope or other equipment
• A brief, painless flash of light during retinal photography

Follow-up and Treatment

If diabetic retinopathy is detected during the screening, your doctor may recommend:

• Laser Photocoagulation: A laser treatment to reduce swelling or prevent further vision loss.
• Vitrectomy: Surgical removal of blood and scar tissue from the eye.
• Anti-VEGF Injections: Medications injected into the eye to reduce swelling and slow disease progression.
• Regular Monitoring: Scheduled follow-up appointments to track changes in your condition and adjust treatment as needed.

Importance of Regular Diabetic Eye Screening

Regular diabetic eye screening is crucial for early detection and management of diabetic retinopathy, which can help prevent vision loss and reduce the risk of blindness. The American Diabetes Association recommends that adults with type 1 or type 2 diabetes undergo a comprehensive eye examination by an ophthalmologist or optometrist at least once a year.
