Glaucoma is characterized by a buildup of pressure in the eye. This occurs when it fails to balance the amount of inner eye fluid produced against the amount that drains away. When too much intraocular pressure — or IOP — builds, the optic nerve also experiences pressure. Left untreated, this can lead to permanent nerve damage and loss of vision.

The precise reasons for glaucoma vary, but here are a few common causes:

• Blocked Trabecular Meshwork: The eye produces a fluid called aqueous humor that normally circulates throughout the eye and eventually exits through a mesh-like channel — the trabecular meshwork. If this channel is blocked, fluid can build up, leading to a high IOP and subsequent glaucoma. Doctors aren’t sure why this channel gets blocked sometimes, but it seems to be an inherited risk.
• Injury or Infection: Traumatic incidents, including injuries or infections, can also lead to glaucoma. This could include a blunt-force impact, chemical burn, or severe infection or inflammation. Blocked blood vessels in the eye, for any of these reasons, can also be to blame.
• Narrow Eye Structure: A more rare type of glaucoma, known as angle-closure glaucoma, occurs when the eye doesn’t drain correctly because the angle between the iris and the cornea is too narrow. The iris then blocks drainage, resulting in a buildup of pressure. This type of glaucoma is also linked to farsightedness and cataracts.

Most people do not experience any symptoms when glaucoma is in its early stages. This is why it’s important to see an eye doctor regularly. They can catch signs of this disease and provide treatment before serious consequences set in. Just how often you should get tested depends on your eye health, family history, and age. Talk to an eye doctor to find out what’s right for you.
