Glaucoma: Diagnosis
Your eye doctor may use tonometry or gonioscopy to test for glaucoma.
- Tonometry: A key test in glaucoma diagnosis is tonometry. A tonometer measures eye pressure, better known as intra-ocular pressure.
- Gonioscopy: Gonioscopy may be performed to look at the angle of the eye to detect if it is open or closed. An inspection of the health of the optic nerve is also important in assessing any damage that may have occurred because of glaucoma. If damage is suspected, the doctor may measure your overall visual field with a computerized perimeter or analyze your nerve fiber layer with scanning laser ophthalmoscopy.
