Tonometry

Opthalmology

Tonometry is an examination, in which the intraocular pressure is measured. The intraocular pressure is a specific pressure on the eyeball. An excessively high intraocular pressure may cause damage to the retina or optic nerve. Tonometry is part of the standard examination done in case of eye problems.

Working
