How is primary open angle glaucoma treated?

Most people with primary open angle glaucoma can be treated with drugs administered as eye drops. Each patient must be carefully assessed to determine which drugs are appropriate.


Eyedrops in use include:

- Alpha agonists: e.g. Brimonidine
- Beta blockers: e.g. Betaxolol
- Carbonic anhydrase inhibotors: e.g. Dorzolamide
- Prostaglandin agonists: e.g. Latanoprost
- Combinations of the above

If eyedrops fail to stop the progression of the glaucoma, then laser or conventional surgery, or oral medication (acetazolamide) is used. Laser trabeculoplasty or filtering surgery improves aqueous drainage and acetazolamide reduces production of aqueous fluid. This reduces the pressure in the eye and prevents further damage to the optic nerve and vision.

Regular physical exercise reduces intraocular pressure and protects the optic nerve, therefore this is an excellent way of additional treatment to the eye.
