Treatment Options

Detection

Regular eye examinations by your ophthalmologist are the best way to detect glaucoma. An ophthalmologist is a medical eye doctor. Your ophthalmologist can detect and treat glaucoma.

During a complete and painless examination, your ophthalmologist will:

  • Measure your intraocular pressure
  • Inspect the drainage angle of your eye
  • Evaluate any optic nerve damage
  • Test the visual field of each eye

Some of these tests may not be necessary for every person. You may need to repeat these tests on a regular basis, to determine if glaucoma damage is increasing over time.

Treatment

As a rule, damage caused by glaucoma cannot be reversed. Eye drops, pills, laser and surgical operations are used to prevent or slow further damage from occurring. With any type of glaucoma, periodic examinations are very important to prevent vision loss. Because glaucoma can worsen without your being aware of it, your treatment may need to be changed over time.

Medications

Glaucoma is usually controlled with eye drops taken several times a day, sometimes in combination with pills. These medications decrease eye pressure, either by slowing the production of aqueous fluid within the eye or by improving the flow leaving the drainage angle. For these medications to work, you must take them regularly and continuously. It is also important to tell all of your doctors about the eye medications you are using.

Laser Surgery

Laser surgery treatments may be effective for different types of glaucoma. The laser is usually used in one of two ways. In open-angle glaucoma, the drain itself is treated. The laser is used to enlarge the drain (trabeculoplasty) to help control eye pressure. In angle-closure glaucoma, the laser creates a hole in the iris (iridotomy) to improve the flow of aqueous fluid to the drain.

Surgery

When surgery is needed to control glaucoma, your ophthalmologist uses miniature instruments to create a new drainage channel for the aqueous fluid to leave the eye. The new channel helps to lower the pressure. Though serious complications of modern glaucoma surgery are rare, they can occur, as with any surgery. Surgery is recommended only if your ophthalmologist feels that it is safer to operate than to allow optic nerve damage to continue.
