Surgery reduces the pressure in the eyes by opening blocked drainage angles or creating a new opening that fluid can flow through to leave the eye. In some cases, surgery may be done to relieve pain caused by glaucoma.
Medicine will usually be tried before surgery is considered.
Doctors can use either a surgical cutting tool or a very focused beam of light, called a laser, to do surgery for glaucoma. Laser surgery is usually the first type of surgery tried. If laser surgery doesn't help, your doctor may try conventional surgery.
Surgery choices for adults-There are three basic types of surgery for glaucoma in adults:
- Surgery to increase drainage of fluid from the eye.
- Surgery to prevent closure of the drainage angle.
- Surgery to decrease the amount of fluid produced in the eye.
