How Diabetes Impacts Eye Health
Diabetes affects the body’s ability to use and regulate blood sugar. When blood sugar remains high over time, it causes damage to tiny blood vessels throughout the body—including those in the eyes. The retina, which converts light into signals the brain interprets, is especially sensitive to these changes.
According to Everett & Hurite’s diabetic retinopathy care information, elevated blood sugar can weaken blood vessel walls and lead to leakage, swelling, and restricted blood flow in the retina. If left untreated, this process can distort vision or lead to permanent blindness in advanced stages.
Common Diabetic Eye Conditions
Several eye conditions are linked to diabetes. Understanding each one helps you recognize early warning signs and seek timely care.
1. Diabetic Retinopathy
One of the leading causes of vision loss in adults, diabetic retinopathy develops when retinal blood vessels become damaged over time. It progresses through four stages, ranging from mild swelling to the growth of fragile new blood vessels that bleed into the eye.
Symptoms may include:
- Blurry or fluctuating vision
- New floaters
- Dark or empty spots in vision
- Sudden vision loss
Everett & Hurite describes stages such as microaneurysms, blood vessel swelling, abnormal vessel growth, and the risk of retinal detachment when scar tissue forms.
2. Diabetic Macular Edema (DME)
This condition occurs when fluid leaks into the macula—the part of the retina responsible for sharp central vision—leading to swelling and distortion. It is a common complication of diabetic retinopathy and may cause difficulty with reading, driving, or recognizing faces.
3. Cataracts
People with diabetes develop cataracts earlier and more rapidly than non-diabetic individuals. High blood sugar causes the lens to become cloudy, resulting in:
- Glare sensitivity
- Hazy or blurred vision
- Difficulty seeing at night
Cataract surgery is a safe and effective treatment offered by Everett & Hurite when cataracts interfere with daily activities.
4. Glaucoma
Diabetes increases the risk of glaucoma, a group of conditions that damage the optic nerve. Elevated eye pressure may develop gradually or suddenly, leading to vision loss if untreated.
Symptoms of Diabetic Eye Issues
Because diabetic eye diseases may progress silently, recognizing early symptoms is vital. Contact an eye specialist if you experience:
- Persistent blurry vision
- Sudden changes in vision
- Floaters or flashes of light
- Difficulty focusing
- Eye pain or pressure
- Dark spots or shadows in your field of vision
Not everyone with diabetic retinopathy experiences symptoms early on. Everett & Hurite emphasize that up to 45% of individuals with diabetes may have some level of retinopathy without realizing it, which makes routine diabetic eye exams essential for early detection.
Routine Eye Exams: A Critical Part of Diabetes Care
Routine diabetic eye exams allow specialists to detect early changes in the retina before damage becomes irreversible. During an exam, an Everett & Hurite ophthalmologist may perform:
- Dilated retinal examination
- Optical coherence tomography (OCT)
- Retinal imaging
- Eye pressure measurement
These tools help identify diabetic retinopathy, macular edema, glaucoma, and other diabetes-related conditions at their earliest stages. Regular exams are recommended annually—or more frequently if retinopathy is already present.
Everett & Hurite’s specialists provide comprehensive diagnostic services and create individualized treatment plans to protect vision for patients across Pittsburgh and the tri-state area.
Treatment Options for Diabetic Eye Disease
Everett & Hurite offers evidence-based treatments tailored to the severity of the condition and the patient’s unique eye health needs.
Anti-VEGF Injections
Medications that block vascular endothelial growth factor (VEGF) help slow the growth of abnormal blood vessels and reduce retinal swelling. These injections are commonly used to treat diabetic retinopathy and macular edema.
Laser Therapy
Laser treatment targets leaking blood vessels to stop or reduce fluid buildup. Focal or grid laser surgery is frequently used alongside anti-VEGF therapy for optimal results.
Corticosteroid Therapy
Steroid injections may be used to control inflammation and swelling. However, Everett & Hurite Eyecare Specialists advise that this approach may increase the risk of cataracts or glaucoma, so it is not recommended for every patient.
Vitrectomy Surgery
In advanced cases involving bleeding into the vitreous gel or significant scar tissue, vitrectomy surgery may be recommended to restore vision and prevent further complications.
Tips for Managing Diabetes to Protect Your Vision
Protecting your eyes requires a combination of medical and lifestyle strategies:
- Maintain healthy blood sugar levels
- Keep blood pressure and cholesterol within recommended ranges
- Follow your primary care provider’s diabetes management plan
- Avoid smoking, which increases retinal damage
- Schedule routine diabetic eye exams
- Monitor for vision changes and report new symptoms promptly
Everett & Hurite underscores that good blood sugar control reduces the risk of severe complications and helps prevent blindness related to diabetic retinopathy.

Frequently Asked Questions
How does diabetes affect your vision?
High blood sugar damages the blood vessels in the retina, leading to swelling, leakage, and restricted blood flow. These changes can distort vision or cause permanent vision loss if untreated.
What are the early symptoms of diabetic eye disease?
Early symptoms may include blurry vision, floaters, difficulty focusing, or changes in central vision. However, many patients experience no symptoms until the disease progresses.
What is diabetic retinopathy?
Diabetic retinopathy is a condition in which high blood sugar damages retinal blood vessels. It progresses through multiple stages and can lead to macular edema, bleeding, or retinal detachment.
How often should people with diabetes get an eye exam?
Annual diabetic eye exams are recommended, though more frequent visits may be necessary if retinopathy or macular edema is present.
What treatments are available for diabetic eye disease?
Treatment may include anti-VEGF injections, laser therapy, corticosteroids, or vitrectomy surgery, depending on the severity of the condition.
