Glaucoma Symptoms

Most people with the disease do not experience any glaucoma symptoms until some vision loss has occurred.

Unfortunately, most people do not notice any symptoms of glaucoma until the disease has significantly damaged their optic nerves. As optic nerve fibers are damaged by glaucoma, small blind spots begin to develop, usually in the side – or peripheral – vision. All vision loss from glaucoma is irreversible.

Glaucoma symptoms

When glaucoma symptoms do present, they can vary depending on the type of glaucoma. Open-angle glaucoma often develops gradually and painlessly, with no early warning signs. Many times the first symptoms of glaucoma occur only after significant vision has already been lost.

Acute angle closure glaucoma, which results from a sudden blockage of drainage channels in the eye, causes a rapid buildup of pressure accompanied by several symptoms of glaucoma, which can include:

  • Blurred vision
  • The appearance of colored rings around lights
  • Pain or redness in the eye

Why is glaucoma harmful to vision?

The optic nerve at the back of the eye carries visual information to the brain. As the fibers that make up the optic nerve are damaged, the amount and quality of information sent to the brain decreases, resulting in vision loss.

Will I go blind from glaucoma?

If diagnosed at an early stage, glaucoma usually can be controlled:

  • If left untreated, side vision (peripheral vision) and central vision can be lost, leading to irreversible blindness.
  • The best way to prevent vision loss with glaucoma is through early diagnosis and treatment.
  • A regular eye examination, including testing for glaucoma, is an important preventive eye care practice for people over the age of 35, even if you have no glaucoma symptoms.
