Description
- The measurement of the ocular pressure is carried out on the patient sitting at the slit lamp in conjunction with other routine microscopic examinations.
- High accuracy of the measurement – the average deviation in any one single examination does not exceed ± 0.5 mm Hg.
- The intraocular pressure in mm Hg is found by multiplying the drum reading by ten.
- Scleral-rigidity is not to be taken into account as the small volumetric displacement of 0.56 mm3 increases the intraocular tension by about 2.5 % only.
- Repeated measuring procedures do not reduce the ocular pressure, as no massaging effect occurs.
- There are no standardization and calibration difficulties.
