What is in this leaflet

What Glaumox is used for
Glaumox is used to lower raised pressure in the eye and to treat glaucoma. Glaucoma is a condition in which the pressure of fluid in the eye may be high. However, some people with glaucoma may have normal eye pressure.
Glaucoma is usually caused by a build up of the fluid which flows through the eye. This build up occurs because the fluid drains out of your eye more slowly than it is being pumped in. Since new fluid continues to enter the eye, joining the fluid already there, the pressure continues to rise. This raised pressure may damage the back of the eye resulting in gradual loss of sight. Damage can progress so slowly that the person is not aware of this gradual loss of sight. Sometimes even normal eye pressure is associated with damage to the back of the eye.
There are usually no symptoms of glaucoma. The only way of knowing that you have glaucoma is to have your eye pressure, optic nerve and visual field checked by an eye specialist or optometrist. If glaucoma is not treated it can lead to serious problems, including total blindness. In fact, untreated glaucoma is one of the most common causes of blindness.
Glaumox is used, either alone or in combination with other eye drops/medicines, to lower raised pressure within your eyes.
Glaumox lowers the pressure in the eye by decreasing the fluid produced and helping the flow of fluid out of the eye chamber.
Glaumox is also used to treat some other conditions such as epilepsy and fluid build up due to heart failure or medicines.
Glaumox belongs to a family of medicines called sulphonamides.
Ask your doctor if you have any questions about why Glaumox has been prescribed for you. Your doctor may have prescribed it for another reason.

Things you must do
