If you have high eye pressure, your healthcare provider may recommend Combigan. This eye drop is specifically designed to lower eye pressure in people with open-angle glaucoma or ocular hypertension. It is generally used when one medication is not enough to control eye pressure. A healthcare provider may occasionally use Combigan off-label to treat acute angle-closure glaucoma, even though it is not approved for this purpose.
Combigan® (brimonidine/timolol) is an eye drop prescribed to lower the pressure in the eyes (intraocular pressure). Specifically, it is approved to lower eye pressure in people with the following conditions:
- Chronic open-angle glaucoma
- Ocular hypertension (high eye pressure that is not accompanied by changes in vision or damage to the optic nerve, as would happen with glaucoma).
Combigan contains two separate active ingredients: brimonidine (an alpha agonist) and timolol (a beta blocker). It is generally used when just one medication alone is not effective enough for controlling eye pressure.
Glaucoma is not a single disease. It is actually a group of diseases sharing certain features, such as:
- High pressure within the eye (intraocular pressure)
- Damage to the optic nerve
- Loss of peripheral (side) vision
- Possible blindness.
Of all the different types, open-angle glaucoma is by far the most common (see Types of Glaucoma).
Although there is no cure for open-angle glaucoma, symptoms can usually be controlled and further damage may be prevented or reduced. The most common glaucoma treatments are:
- Traditional surgery (see Glaucoma Surgery)
- Medications (see Glaucoma Medications)
- Laser surgery (see Glaucoma Laser Surgery).
Combigan can be used by itself or, if necessary, combined with other types of glaucoma medications or treatments.
Not everyone with high eye pressure has glaucoma, although high eye pressure can lead to this condition. Thus, effectively treating high eye pressure can help prevent glaucoma.
