Quick Summary (TL;DR): Corneal diseases are the second leading cause of blindness in India, affecting over 1.2 million people. Conditions like corneal ulcers (keratitis), keratoconus, and corneal opacities cause severe vision loss if left untreated. Retina Centre offers advanced corneal evaluations, specialized medical management, and surgical consultations in Guwahati and Northeast India.

What is Corneal Disease?
The cornea is the clear, dome-shaped outer layer of your eye that acts as a protective window and focuses light onto the retina. When the cornea becomes damaged due to infection, injury, genetic conditions, or degeneration, light cannot focus properly, leading to blurred vision or complete sight impairment.
Corneal Blindness in India: The Data & Burden
In India, corneal opacity is a major public health challenge. According to data from the National Blindness and Visual Impairment Survey and the World Health Organization (WHO):
1.2 Million People in India suffer from corneal blindness, with approximately 25,000 to 30,000 new cases added annually.
Agricultural Injuries: Over 60% of infectious corneal ulcers (keratitis) in rural India stem from minor trauma caused by vegetative material (paddy leaves, twigs, or soil dust).
Fungal Keratitis Burden: India accounts for one of the highest rates of fungal corneal infections worldwide due to warm, humid tropical climates.
Preventability: Over 90% of corneal blindness cases in India are preventable if treated within the first 24 to 48 hours of injury or infection.

| Condition | Primary Cause | Key Symptoms |
| Infectious Keratitis (Corneal Ulcer) | Bacterial, fungal, or viral infections (often after vegetative injury) | Severe eye pain, white spot on cornea, yellow discharge, redness |
| Keratoconus | Progressive thinning and cone-like bulging of the cornea | Frequent changes in eyeglass prescription, distorted vision, light sensitivity |
| Pterygium (Surfer’s Eye) | Fleshy growth over the cornea caused by UV exposure and dust | Gritty sensation, redness, astigmatism as it grows over the line of sight |
| Corneal Dystrophies & Degenerations | Genetic conditions affecting corneal clarity (e.g., Fuchs’ Dystrophy) | Cloudy vision, morning haze, eye discomfort |
Warning Symptoms: When to See an Eye Specialist
Seek urgent evaluation if you experience any of the following “red flag” symptoms:
Pain or throbbing in or around the eye after minor trauma.
A visible white or grayish spot on the dark part of your eye.
Sudden drop in vision clarity or severe photophobia (sensitivity to light).
Persistent redness and discharge that doesn’t improve with basic lubricating drops.

Frequently Asked Questions (FAQs)
What is the primary cause of corneal ulcers in India?
Agricultural eye trauma from plants, soil, or organic debris is the leading cause of bacterial and fungal corneal ulcers in India.
Can corneal blindness be cured?
Yes, depending on the severity. Early infections can be cured with targeted medications. Advanced corneal scarring can often be restored through corneal transplantation (keratoplasty).
Where can I get corneal evaluation in Guwahati and Northeast India?
You can book an expert evaluation at Retina Centre, offering comprehensive diagnostic and eye care services in Guwahati.
