Glaucoma Q&A

What is glaucoma?

Glaucoma is a group of chronic eye conditions that impact your optic nerve. It can affect one or both eyes. And left untreated, it can lead to vision loss and blindness.

Initially, you may have no apparent symptoms, but without treatment, your peripheral vision eventually begins to fade. Over time, glaucoma can lead to tunnel vision and eventually even blindness.

Once glaucoma damages your optic nerve, it's irreversible. But by detecting and treating it early, Dr. K can slow the disease’s progression and minimize the symptoms.

To screen for glaucoma, Dr. K administers a range of tests, including:

  • Visual acuity test
  • Visual field test
  • Dilated eye exam
  • Tonometry
  • Pachymetry

What causes glaucoma?

Glaucoma is associated with pressure inside the eye. In a healthy eye, fluid flows through a channel in the front of the eye. When you have glaucoma, this channel becomes blocked and causes the fluid to build up, creating pressure.

The cause is unknown, but heredity is a factor.

In rare cases, glaucoma develops after an injury to the eye, a severe eye infection, or an inflammatory condition. It may also develop when blood vessels become blocked inside the eye.

How is glaucoma treated?

For optimal results, glaucoma treatment should begin right after you’re diagnosed. The type of treatment Dr. K recommends depends on the type of glaucoma you have and how far it’s progressed. The most common treatments include:

  • Medications
  • Laser trabeculoplasty
  • Surgery


In the early stages of treatment, eye drops can lower eye pressure and reduce the amount of fluid in your eye. If medication doesn't reduce the pressure in your eye, Dr. K may suggest a procedure that helps drain your eye and relieve pressure.
