Glaucoma is one of the leading causes of irreversible vision loss worldwide, yet many people don’t fully understand how it damages the eye. Often called the “silent thief of sight,” glaucoma typically progresses without noticeable symptoms in its early stages. At Westchester Eyes, we emphasize early detection through medical eye exams and advanced diagnostic technology to help protect your optic nerve and preserve your vision.
 

The Role of the Optic Nerve in Vision

The optic nerve plays a critical role in how you see. It acts as a communication highway, transmitting visual information from the retina to the brain. This nerve is made up of more than one million nerve fibers, all of which must function properly to maintain clear, detailed vision.

When the optic nerve is damaged, the brain receives incomplete or distorted visual signals. Unfortunately, optic nerve fibers do not regenerate, which is why early detection and treatment of glaucoma are essential.
 

How Glaucoma Damages the Optic Nerve

Glaucoma most commonly affects the optic nerve through increased pressure inside the eye, known as intraocular pressure (IOP). Fluid normally flows in and out of the eye to maintain healthy pressure. When this fluid does not drain properly, pressure builds up and places stress on the optic nerve.

Over time, this pressure damages the nerve fibers, leading to:

• Gradual loss of peripheral vision
• Development of blind spots
• Progressive narrowing of the visual field
• Potential central vision loss in advanced stages

Some forms of glaucoma can also damage the optic nerve even when eye pressure appears normal, making regular medical eye exams even more important.
 

Why Glaucoma Often Goes Undetected

One of the most dangerous aspects of glaucoma is that it usually develops slowly and painlessly. Many patients do not experience symptoms until significant optic nerve damage has already occurred. Vision loss often starts in the periphery, which can be difficult to notice during everyday activities.

This is why routine vision screenings are not enough. Glaucoma requires a thorough medical eye exam to detect early nerve changes before vision is affected.
 

Detecting Optic Nerve Damage with Advanced Technology

At Westchester Eyes, we use advanced diagnostic technology to evaluate the health of the optic nerve and identify glaucoma at its earliest stages. These tools allow us to detect subtle changes long before vision loss becomes noticeable.

Advanced testing may include:

• High-resolution imaging of the optic nerve
• Measurement of retinal nerve fiber thickness
• Visual field testing to detect early blind spots
• Accurate monitoring of intraocular pressure trends

By combining detailed imaging with clinical expertise, we can track even the smallest changes over time and adjust treatment plans as needed.
 

Stay Ahead of Glaucoma with Westchester Eyes

Glaucoma affects the optic nerve by slowly damaging the nerve fibers responsible for transmitting visual information to the brain. Because this damage is permanent and often symptom-free in its early stages, regular medical eye exams are the most effective way to protect your sight. With advanced diagnostic technology and personalized care, early detection can make a lifelong difference in preserving your vision.
