World Glaucoma Awareness Week, observed from March 9th to 15th, is a crucial time to shed light on one of the leading causes of irreversible blindness worldwide. The theme for 2025, “See the Future Clearly,” emphasises the significance of early detection, regular eye care, and community education in preventing vision loss due to glaucoma. At Shekar Eye Hospital, we are committed to spreading awareness and encouraging individuals to take proactive steps toward protecting their vision.
Understanding Glaucoma: The Silent Thief of Sight
Glaucoma is a group of eye diseases that cause damage to the optic nerve, primarily due to increased intraocular pressure (IOP). This condition develops gradually, often without noticeable symptoms in its early stages. By the time vision loss becomes apparent, the damage is often irreversible. According to the World Health Organization, glaucoma is the second leading cause of blindness globally, affecting millions of people.
Types of Glaucoma
Open-Angle Glaucoma (Chronic Glaucoma)
The most common type, where fluid drainage in the eye becomes inefficient, leading to increased eye pressure.
Progresses slowly and painlessly, making regular eye check-ups vital for detection.
Angle-Closure Glaucoma (Acute Glaucoma)
Occurs when the iris blocks the drainage angle, causing a rapid increase in eye pressure.
Symptoms include severe eye pain, nausea, blurred vision, and headaches. Requires immediate medical attention.
Normal-Tension Glaucoma
Optic nerve damage occurs despite normal eye pressure levels.
Often linked to reduced blood flow to the optic nerve.
Congenital Glaucoma
A rare condition present at birth due to improper eye drainage development.
Symptoms in infants include cloudy corneas, excessive tearing, and light sensitivity.
Why Early Detection Matters
Early detection is the key to preventing glaucoma-related vision loss. Since symptoms often go unnoticed, routine eye examinations play a crucial role in diagnosing glaucoma before significant damage occurs. A comprehensive eye check-up includes:
- Tonometry: Measures intraocular pressure.
- Ophthalmoscopy: Examines the optic nerve for signs of damage.
- Perimetry (Visual Field Test): Detects any blind spots or peripheral vision loss.
- Gonioscopy: Assesses the drainage angle of the eye.
Who is at Risk?
Certain factors increase the likelihood of developing glaucoma, including:
- Age: People over 40 are at higher risk.
- Family History: A hereditary component makes those with a family history more susceptible.
- Medical Conditions: Diabetes, hypertension, and migraines may contribute to glaucoma.
- Eye Injuries or Surgeries: Trauma to the eye can increase risk.
Treatment Options
While there is no cure for glaucoma, timely intervention can slow its progression and prevent further vision loss. Treatment options include:
- Medicated Eye Drops: Reduce eye pressure by improving fluid drainage or decreasing fluid production.
- Oral Medications: Help control intraocular pressure.
- Laser Therapy: YAG peripheral iridotomy which opens the angle and clears the pupillary block thereby lowering the intra-ocular pressure in cases of angle closure glaucoma and narrow angles
- Surgery: In severe cases, surgical procedures like trabeculectomy or shunt implants may be recommended.
The Role of Awareness and Community Education
World Glaucoma Awareness Week aims to educate people about the importance of eye health and early diagnosis. Here’s how you can contribute:
Get Regular Eye Exams: Encourage friends and family to prioritise eye check-ups.
Know the Symptoms: Be aware of any vision changes and seek medical help promptly.
Spread the Word: Use social media to share information and encourage others to learn about glaucoma.
Support Research and Advocacy: Participate in awareness campaigns and support organisations working to find better treatments and a cure.

Frequently Asked Questions (FAQs)
1. What are the early signs of glaucoma?
Glaucoma often has no early symptoms, but gradual peripheral vision loss, blurred vision, and eye pressure changes can be warning signs.
2. Can glaucoma be prevented?
While glaucoma cannot be prevented, regular eye exams and early detection can help manage the condition and prevent vision loss.
3. Who should get tested for glaucoma?
Everyone over 40, individuals with a family history of glaucoma, diabetics, and those with high blood pressure should undergo regular glaucoma screenings.
World Glaucoma Awareness Week is a reminder that vision is precious. Let’s work together to See the Future Clearly by taking proactive steps to safeguard our eye health.
