How Glaucoma Affects the Optic Nerve and Vision

Glaucoma is one of the leading causes of irreversible vision loss worldwide, yet it often develops silently, with little to no noticeable symptoms in its early stages. Understanding how this condition affects your overall vision is key to early detection and successful management.

The Connection Between Glaucoma and the Optic Nerve

The optic nerve is a vital part of your visual system - it carries visual information from your eye to your brain. In glaucoma, increased intraocular pressure (IOP) or other factors damage the delicate fibers of the optic nerve. Over time, this damage prevents signals from reaching the brain, leading to gradual vision loss.

Initially, glaucoma affects peripheral vision, which can go unnoticed without a professional exam. As the disease progresses, central vision may also become impaired. Because this damage cannot be reversed, early diagnosis is essential to preserving sight.

Why Medical Eye Exams Are So Important

Routine eye exams play a critical role in detecting glaucoma before it causes noticeable vision loss. During a medical eye exam at Eyes of San Antonio, our optometrists assess your overall eye health, measure eye pressure, and examine the optic nerve for any signs of damage. Even if your vision seems fine, glaucoma can still be developing without symptoms. Regular exams allow for early intervention - helping to prevent or slow the progression of the disease.

What to Expect During a Glaucoma Exam

A glaucoma evaluation is quick, comfortable, and thorough. Here’s what you can expect during your visit to Eyes of San Antonio:

• Tonometry: Measures the pressure inside your eye (intraocular pressure).

• Ophthalmoscopy: Examines the shape, color, and health of the optic nerve.

• Visual Field Testing: Maps your peripheral vision to identify blind spots.

• OCT (Optical Coherence Tomography): Captures detailed images of your optic nerve fibers.

These tests help your eye doctor in San Antonio, TX detect glaucoma in its earliest stages and monitor any changes over time.
