Introduction

Diabetes doesn’t just affect blood sugar—it impacts nearly every organ, including the eyes. Over time, uncontrolled diabetes can lead to diabetic retinopathy, cataract, and glaucoma, all of which may cause vision loss if left untreated.

At Moolchand Hospital, one of the top hospitals in Delhi, superb surgeons like Dr. Krishna Vaitheeswaran, Dr. Preetinder Kaur, and Dr. Monika Nadar combine cutting-edge ophthalmic technology with compassionate care, guided by integrity and affordability, to help patients preserve their vision.

How Diabetes Affects the Eyes

Chronic high blood sugar can damage delicate eye structures in several ways:

Diabetic Retinopathy: High glucose levels damage tiny blood vessels in the retina, leading to bleeding or fluid leakage that can distort vision.
Cataract: Diabetic patients often develop lens clouding at a younger age.
Glaucoma: Increased eye pressure can harm the optic nerve, causing gradual vision loss.
Macular Edema: Fluid buildup in the central retina (macula) blurs fine details needed for reading or recognizing faces.

Early Warning Signs to Watch For

Many diabetic eye conditions progress silently until vision loss occurs. Early symptoms may include:

Blurred or fluctuating vision
Seeing floaters or dark spots in the field of view
Difficulty reading or poor night vision
Eye redness or mild discomfort (in some cases)

If you experience these signs, immediate evaluation by an ophthalmologist is crucial.

Preventive Measures and Management

Prevention and early intervention remain the most effective strategies for protecting eyesight in people with diabetes.

1. Regular Eye Exams:
Schedule comprehensive dilated eye examinations at least once a year to detect problems before symptoms appear.

2. Blood Sugar Control:
Maintain HbA1c within the target range to minimize vascular damage to the retina.

3. Healthy Lifestyle:
Adopt a balanced diet, regular exercise, and adequate hydration to improve circulation and reduce inflammation.

4. Monitor Blood Pressure and Cholesterol:
Controlling these parameters reduces the risk of retinal bleeding and swelling.

5. Prompt Treatment:
If complications are found, laser therapy, anti-VEGF injections, or microsurgery can preserve sight and prevent further damage.
