Viral meningitis is common and contagious, but it is rarely serious or fatal and does not require antibiotics. The more serious meningococcal bacteria are the leading cause of meningitis in adolescents ages 11 to17, and while theyâre rare, they can be fatal.
Test Overview. A tonometry test measures the pressure inside your eye, which is called intraocular pressure (IOP). This test is used to check for glaucoma, an eye disease that can cause blindness by damaging the nerve in the back of the eye (optic nerve ).
In general and depending on the patient's risk factors, check IOP every 3-12 months. If the patient is a low-tension glaucoma suspect with normal IOP but suspicious optic nerve head cupping, conduct a diurnal assessment of IOP. Perform visual field examinations every 6-12 months.
