World Sight Day: Understanding Glaucoma

Every October, World Sight Day brings global attention to the importance of protecting vision and preventing avoidable blindness. At Chicago Glaucoma Consultants, we focus on educating our community about glaucoma — one of the most preventable causes of vision loss when diagnosed early.

What Is Glaucoma?

Glaucoma is a group of diseases that damage the optic nerve, often due to elevated eye pressure. Over time, this damage leads to permanent vision loss — usually starting with peripheral vision.

The most common types include:

• Open-angle glaucoma
• Narrow-angle (angle-closure) glaucoma
• Normal-tension glaucoma
• Secondary glaucoma

Why Early Detection Is Essential

Glaucoma is often called the “silent thief of sight” because symptoms usually do not appear until significant damage has occurred. By the time most patients notice vision changes, a large portion of optic nerve fibers may already be affected.

Regular screenings allow ophthalmologists to detect changes long before symptoms occur.

Common Signs of Glaucoma (When They Do Appear)

While early stages are often symptom-free, advanced glaucoma may cause:

• Blurred or patchy peripheral vision
• Halos around lights
• Eye pain or pressure
• Headaches
• Sudden vision changes (this can be an emergency)

How Chicago Glaucoma Consultants Helps Protect Your Sight

We offer comprehensive care for all stages of glaucoma, including:

• Glaucoma evaluations and second opinions
• Eye pressure and drainage angle testing
