What You Should Know About Glaucoma

Glaucoma is a group of diseases that can damage the eye’s optic nerve and result in vision loss and blindness. It is one of the main causes of blindness in the United States. However, with early treatment, you can often protect your eyes against serious vision loss. Therefore it is very important that it be diagnosed early. There are two types of glaucoma:

Open-angle Glaucoma

This is the most common type, also called wide-angle glaucoma. In open-angle glaucoma, the structures of the eye appear normal. However, eye fluid does not flow properly through the drain of the eye. 

Angle-closure Glaucoma

This type is also called acute or narrow-angle glaucoma. This type is more common in Asia than in the West. The angle between the iris and the cornea is too narrow, which blocks the iris and causes poor drainage and sudden buildup of pressure in the eye.

Glaucoma is often called the "sneak thief of vision" because it's often accompanied by no symptoms. It's important to detect glaucoma early. Get a complete eye exam with Dr. Maher every one to two years. In the rare event that intraocular pressure rises to severe levels, tou may feel sudden eye pain, headache, blurred vision, or see halos around lights. If you have any of the following symptoms, contact Dr. Maher's office immediately:

  • See halos around lights
  • Vision loss
  • Red eye
  • Hazy eye (particularly in infants)
  • Nausea, vomiting
  • Eye pain
  • Tunnel vision
