An arteriotonograph. A new instrument for measuring the pressure in the ophthalmic artery

J. Stepanik

A new piece of equipment was developed that records the intraocular pressure at the time of biomicroscopically observed collapse of the central retinal artery on the optic disc. A special contact lens with a properly adjusted pressure-sensitive probe allows exact observation of the optic disc and manual compression of the eye, whereas the foot-plate of the probe perceives the intraocular pressure through the applanated peripheral cornea.
