Diabetic Retinopathy: How Diabetes Affects Your Eyes
The Indian Council of Medical Research reports that more than 10 crore people in India are living with diabetes. A significant number of them may eventually develop diabetic retinopathy, a serious eye condition. It is one of the leading causes of blindness in working-age individuals worldwide, and in many cases, it is preventable with early detection.
Many people with diabetes are aware of the risks to their heart and kidneys, but eye health is often overlooked. Regular eye checkups are just as important as monitoring blood sugar levels. Detecting changes early can make the difference between preserving vision and permanent damage.
How Does Diabetes Affect the Eyes?
The retina is the light-sensitive layer at the back of the eye. It is supported by a network of tiny blood vessels. When blood sugar levels remain high for a long time, these vessels can become damaged. They may swell, leak, or grow abnormally, leading to diabetic retinopathy.
The condition develops gradually. In the early stage, called non-proliferative diabetic retinopathy, the blood vessels weaken and leak fluid into the retina. As the disease progresses to the proliferative stage, new and fragile blood vessels begin to form on the surface of the retina. These vessels can bleed easily and may create scar tissue, which can pull on the retina and, in severe cases, lead to retinal detachment.
Who Is at Risk of Diabetic Retinopathy?
The risk increases with the duration of diabetes and poor blood sugar control. Key risk factors include:
- Diabetes for more than ten years
- Consistently high HbA1c levels
- High blood pressure along with diabetes
- High cholesterol levels
- Pregnancy in women with diabetes
- Smoking
Both Type 1 and Type 2 diabetes can lead to retinopathy. Managing overall health is crucial. An endocrinologist in Ghaziabad or a diabetes specialist helps control the underlying causes, while an eye specialist monitors retinal health.
How Is Diabetic Retinopathy Diagnosed?
The most common way to check for eye problems is a dilated fundus examination. In this test, eye drops are used to enlarge the pupil so the doctor can examine the retina clearly. It is a painless procedure and usually takes less than 30 minutes.
Additional diagnostic tools include:
- Fundus photography, which captures detailed images of the retina for documentation and comparison over time
- Optical Coherence Tomography (OCT), which provides cross-sectional images of the retinal layers to detect swelling or fluid buildup
- Fluorescein angiography, where a dye is injected into the bloodstream to map blood flow in the retinal vessels and identify areas of leakage or blockage
If you experience sudden changes in vision, new floaters, or a dark curtain over your visual field, search for an emergency hospital near you and seek immediate medical attention. These symptoms may indicate retinal detachment and require urgent treatment.
What Treatments Are Available?
Treatment depends on the stage of the disease and whether the central part of the retina, known as the macula, is affected.
Intravitreal Injections
Anti-VEGF drugs such as ranibizumab or bevacizumab are injected into the eye to slow abnormal blood vessel growth and reduce fluid leakage. These are among the most widely used treatments for diabetic macular oedema.
Laser Photocoagulation
A focused laser is used to seal leaking blood vessels and reduce the growth of abnormal vessels. Panretinal photocoagulation is commonly used in proliferative retinopathy.
Vitrectomy
In advanced cases where bleeding into the vitreous gel or retinal detachment has occurred, a surgical procedure called vitrectomy is performed to remove the blood-filled gel and repair the retina. An endocrinologist in Indirapuram, working with a vitreoretinal surgeon, ensures optimal blood sugar control before and after surgery for the best outcomes.

FAQs
Q1. What is diabetic retinopathy?
Diabetic retinopathy is damage to the retina’s blood vessels caused by prolonged high blood sugar levels. It is a leading cause of vision loss in people with diabetes.
Q2. Can diabetic retinopathy occur without symptoms?
Yes. In the early stages, most people have no pain or visible changes in vision. This is why annual retinal screening is essential for everyone with diabetes, even when vision feels normal.
Q3. How is diabetic retinopathy diagnosed?
A dilated eye examination is the standard method. OCT imaging and fundus photography are used to assess the extent of retinal changes and monitor progression over time.
Q4. What treatments are available for diabetic retinopathy?
Anti-VEGF injections, laser photocoagulation, and vitrectomy are the main treatments, chosen based on the stage of the condition and the degree of macular involvement.
