title: [Transpalpebral tonometer for measuring intraocular pressure].
abstract: Two new portable instruments--an ophthalmotonometer (TGDc-01) and a pressure indicator (IGD-02)--which make it possible to measure the intraocular pressure (IOP) through the eyelid, were worked out. The operation of both instruments is based on determining the acceleration of freely falling rod after its interaction with the elastic eye surface. The readings of TGDc-01 correlate with the genuine IOP, and those of IGD-2--with the tonometric pressure for Maklakov's tonometer with a weight of 10 g. The accuracy of both instruments is sufficient for clinical purposes; there is no need to use anesthetics or to sterilize the instruments, which are easy in usage. They can be used not only in ophthalmologic examination rooms but also at home.
