This test measures the pressure within the eye. A test result showing an increase in pressure may suggest a diagnosis of glaucoma. Besides measuring the pressure within the eye, tests can also identify damage to the optic nerve and measure accuracy of peripheral vision. These tests may involve examination of the eye, taking pictures of the nerve fibers within the eye, or using a laser to scan the back of the eye for signs of damage in the nerve fibers there. All of these tests can be done by an ophthalmologist.
Glaucoma treatment can include medicines or, sometimes, surgery.
The most common treatment is medication that lowers the pressure within the eye. If medications create intolerable side effects or don't control eye pressure, surgery may be necessary. This may involve the use of lasers. Certain operations open a passage in order to drain the excess fluid. Sometimes silicone drainage implants are used.
