Diabetes is closely linked to eye health, affecting vision alongside various other parts of the body like the kidney . It can lead to serious vision problems or even permanent blindness if not managed promptly. Most people assume that vision complications develop only at an advanced stage of diabetes, but in reality, the first sign can appear long before the serious stage. Both long-term and newly diagnosed diabetic patients should understand the link between diabetes and eye health. It enables them to take proper medical steps, ensuring healthy vision for the future. Renuka Eye Institute, a top-rated eye hospital in Kolkata, is here to guide you in understanding these diseases, their early signs, and prevention.
What is diabetic eye disease?
Diabetes is a chronic condition that causes high blood sugar levels due to the unnatural production and function of insulin. It causes various vision problems, which are called diabetic eye diseases.
How does it damage?
High blood sugar levels damage the tiny blood vessels and tissues inside the eyes, causing swelling, leakage, or even complete closure. This abnormality causes disruption in sending visual signals to the brain and leads to vision changes.
The diseases
- Diabetic Retinopathy: The prominent cause of permanent blindness due to high blood glucose levels, causing haemorrhage in the tissues.
- Diabetic Macular Edema: Happens when retinal blood vessels leak fluid into the macula.
- Cataract: Is commonly developed among elderly people. But diabetic patients are more likely to be affected by it.
- Glaucoma: Is caused by high pressure, impairing the optic nerve. A diabetic patient has double the risk of developing glaucoma compared to a normal person.
Early warning signs
These diseases develop quietly. But if you experience any of the changes listed below, you have to schedule a diabetic eye screening immediately.
- Blurry Vision:is one of the first signs. It is seen at the beginning of diabetes treatment.
- Difficulty in night vision: Many diabetic patients face a decline in night vision.
- Floaters: Small dark spots and strings are seen in the visual field.
- Frequent vision changes: Day-to-day or hour-to-hour changes happen. Prescriptions of eyeglasses may change frequently.
- Faded colour: Sometimes colours appear dull or less vibrant in the vision.
- Vision loss: Temporary vision loss in one eye occurs.
- Eye strain:Feeling of heaviness, pain, dryness, fatigue during reading, and using a digital screen.
- Sensitivity to light: Disruption of the eye’s ability to process light. It increases the sensitivity to light.
The Tests
These diseases usually progress silently until vision is noticeably impaired. People with high blood sugar should undergo a comprehensive eye exam regularly. The screenings are:
- Optical coherence tomography
- Fundus photography
- Fluorescein angiography
Treatment
Effective treatment plans depend on the severity and extent of the condition. The following common treatments are applied to stop the progression and preserve the vision:
- Drugs: Eye doctors begin the treatment by using drops and oral medicines to manage the symptoms and monitor the changes.
- Anti- VEGF Injections: Anti-vascular endothelial growth factor is injected into the eye directly by eye experts for severe cases.
- Laser therapy: Diabetic eye disease doctors use laser treatment (photocoagulation) to address the critical conditions.
- Surgery: In advanced cases, eye surgeons perform surgeries to preserve vision. Retina specialists perform vitrectomy for diabetic retinopathy and diabetic macular edema. Cataract specialists and glaucoma specialists also perform operations for cataracts and glaucoma.
