 Glaucoma is a common eye disease that needs intervention by an eye doctor. Often referred to as the "silent thief of sight" it primarily affects adults who are older than 60. At Vision Source Castle Hills in San Antonio, we provide effective treatment options for our patients dealing with glaucoma.


What Is Glaucoma?

Glaucoma is an eye condition that affects the optic nerve. It is caused by an increase in pressure inside the eye. The optic nerve is what sends signals from the eye to the brain, allowing you to see. When this nerve is damaged, it can cause vision loss and even blindness.

Glaucoma Types

The forms of glaucoma are explained in more detail below:

  • Open-angle glaucoma: Open-angle glaucoma is the most prevalent form of glaucoma, in which case the eye's drainage canals get blocked over time. This happens gradually and painlessly, so you may not detect any vision changes until it has advanced.
  • Angle-closure glaucoma: This type of glaucoma is less common. However, it's much more severe. Angle-closure glaucoma happens when the iris bulges forward. This blocks the eye's drainage canals and increases pressure inside the eye quickly, causing severe pain, headaches, vomiting, and even blurred vision. It is considered a medical emergency so don't take these symptoms lightly.

Diagnosis and Treatment for Glaucoma

As we mentioned, glaucoma is also referred to as the "silent thief of sight." Did you know that more than half of people who have glaucoma don't even know it? In fact, it's estimated that roughly three million Americans have glaucoma. A comprehensive eye exam is necessary because it is the only way to detect glaucoma. This is why it's so important for adults over the age of 60 to have regular eye exams.

Testing for glaucoma involves a dilated eye exam. During the exam, we will measure the pressure inside of your eye and check for any damage to your optic nerve. If we find glaucoma, don't worry. There are treatments available that can help prevent vision loss. Once glaucoma has been diagnosed, our team at Vision Source Castle Hills will work with you to develop a treatment plan.
