What Is Glaucoma?

Glaucoma is a group of eye diseases that damage the optic nerve, which transmits visual information from the eye to the brain. The optic nerve is essential for healthy vision. Once damaged, vision loss cannot be reversed. Glaucoma often develops when increased pressure inside the eye damages optic nerve fibers over time.  Glaucoma can also occur even when eye pressure appears normal.

Why Is Glaucoma Called the “Silent Thief of Sight”?

Unlike many other health conditions, glaucoma usually develops without noticeable symptoms during its early stages. Most people experience:

• No pain
• No redness
• No obvious vision problems
• No warning signs

As the disease progresses, peripheral (side) vision gradually deteriorates. By the time symptoms become noticeable, permanent optic nerve damage may have already occurred. This silent progression makes early detection absolutely critical.

WHO and Global Eye Health

The World Health Organization emphasizes the importance of early diagnosis and treatment of eye diseases to prevent avoidable vision loss.

According to WHO:

• More than 2 billion people worldwide have some form of vision impairment.
• At least 1 billion cases could have been prevented or have not yet been addressed.
• Glaucoma remains one of the leading causes of irreversible blindness globally.

WHO promotes:

• Regular eye examinations
• Early screening programs
• Improved healthcare access
• Technological innovations that enhance diagnosis

Artificial Intelligence is becoming an important tool supporting these global goals.

Types of Glaucoma

Understanding the different forms of glaucoma helps highlight why accurate detection is so important.

• Slow progression
• No early symptoms
• Gradual vision loss

Many patients remain unaware they have the disease for years.

2. Angle-Closure Glaucoma

Less common but more dangerous. Symptoms may include:

• Severe eye pain
• Blurred vision
• Headaches
• Nausea

This condition can become a medical emergency.

3. Normal-Tension Glaucoma

Optic nerve damage occurs even when eye pressure remains within normal ranges. This type demonstrates why pressure measurements alone may not detect all glaucoma cases.

4. Secondary Glaucoma

Occurs due to:

• Eye injuries
• Inflammation
• Certain medications
• Other medical conditions
