Although open-angle glaucoma cannot be cured, it can usually be controlled. The most common treatments are as follows:

• Medications: These may be either in the form of eyedrops or pills. Some drugs are designed to reduce pressure by slowing the flow of fluid into the eye. Others help to improve fluid drainage.
  
  For most people with glaucoma, regular use of medications will control the increased fluid pressure. But these drugs may stop working over time, or they may cause side effects. If a problem occurs, the eye care professional may select other drugs, change the dose, or suggest other ways to deal with the problem.
• Laser surgery: During laser surgery, a strong beam of light is focused on the part of the anterior chamber where the fluid leaves the eye. This surgery results in a series of small changes that make it easier for fluid to exit the eye. Over time, the effect of laser surgery may wear off. Patients who have this form of surgery may need to keep taking glaucoma drugs.
• Surgery: Surgery can also help fluid escape from the eye and thereby reduce the pressure. However, surgery is usually reserved for patients whose pressure cannot be controlled with eyedrops, pills, or laser surgery.
