Early detection and treatment of glaucoma are important for controlling the condition and preventing blindness.
- Eye structure. Ophthalmoscopy, gonioscopy, slit lamp exam, and optic coherence tomography all check the structures of the eye.
- Eye pressure. Tonometry measures the pressure in the eye (intraocular pressure, or IOP).
- Vision tests . These include tests to check for visual acuity and loss of side and central vision (perimetry testing).
- Cornea thickness. Tests such as ultrasound pachymetry measure the thickness of the clear front surface of the eye (cornea). Cornea thickness, along with intraocular pressure, helps determine your risk for glaucoma.
After glaucoma is diagnosed, eye exams are done on a regular basis to monitor the disease.
If you are younger than 40 and have no known risk factors for glaucoma, the American Academy of Ophthalmology (AAO) recommends that you have a complete eye exam every 5 to 10 years. This includes tests that check for glaucoma.2 The AAO suggests more frequent routine eye exams as you age, even if you aren't at increased risk for glaucoma.
