Glaucoma is the increased pressure inside the eye (intraocular pressure), which means that the eye has too much aqueous humor in it.

Laser treatment is recommended in certain selected cases of Glaucoma to create an alternative pathway for the drainage of the fluid. After laser, few patients also need to use medications to keep the pressure under control.

The surgery increases the drainage of the fluid. Cryopexy or Cycloablation are used in uncontrolled cases, and involve partial or total destruction of the tissues that produce the fluid in the eye.
