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 ).
Accurate and precise IOP readings are imperative to evaluate a patientâs risk of progressive optic nerve damage. Inaccurate or inconsistent IOP measurements prevent the clinician from making accurate treatment and management decisions and may put the patient at risk for visual field loss.
