What is Glaucoma?

The term glaucoma encompasses a group of diseases that result in optic nerve damage and vision loss. Because of the way glaucoma affects the optic nerve, the vision loss often presents as reduction of the visual field or peripheral vision loss.

Glaucoma is a significant cause of vision loss and blindness in America. Over 1 million Americans over 65 have experienced vision loss from glaucoma. The best way to protect your vision from glaucoma is with an annual eye exam.

Types of Glaucoma

Open-angle glaucoma is the most common type of glaucoma, accounting for 90% of all glaucoma cases. This type of glaucoma progresses slowly and many patients show no symptoms until they have lost a significant portion of their vision.

It is caused by the eye’s drainage canal slowly clogging. The name open-angle glaucoma comes from the wide and open angle between the iris and the cornea that is characteristic of this type of glaucoma.

Angle-closure glaucoma is much less common than open-angle glaucoma. It’s caused by blocked drainage canals, leading to a sudden increase in intraocular pressure. Angle-closure glaucoma occurs very quickly, making the symptoms very noticeable. If you develop severe eye pain and haloes in your vision, seek immediate medical attention as they could be signs of acute angle-closure glaucoma.

Also known as low-tension or normal-pressure glaucoma, this type of glaucoma occurs despite normal intraocular pressure. Even though the eye pressure is normal or close to normal, normal-tension glaucoma can still occur, causing damage to the optic nerve and your vision.

Congenital glaucoma happens in infants and it is caused by incorrect or incomplete development of the eyes’ drainage canals. It’s very rare and is thought to have a hereditary component.

How We Diagnose & Treat Glaucoma

Annual Eye Exams

An annual eye exam is the best way to detect glaucoma, especially open-angle glaucoma. During an eye exam, your optometrist will perform a visual field test. A visual field test will help detect the peripheral vision loss associated with glaucoma.

Risk Factors

During an eye exam, your optometrist can assess you for risk factors associated with glaucoma, including:

  • Family history of glaucoma
  • Advancing age
  • High degree of myopia (nearsightedness)
  • Hypertension
  • Diabetes

Medical Therapy & Surgery

If you’re diagnosed with glaucoma, the disease can be treated. Medical therapy to lower intraocular pressure is the first line of treatment in most cases. When medication is not effective, patients are referred for surgery. Surgery might include laser treatment or an incision into the eye to relieve the pressure depending on the patient and the severity of the glaucoma.
