Schiötz tonometers. An assessment of their usefulness.
THERE is no doubt that applanation tonometry gives more accurate information about the level of intra-ocular pressure than does indentation tonometry. This increased accuracy is due to the fact that applanation readings approach very closely to the levels of pressure in the undisturbed eye (Po), owing to the small volume of fluid displaced by the application of the tonometer (Goldmann, 1957). A...
متن کاملassessment of propofol usefulness as an anesthetic agent during colonoscopy
â background propofol is used as a sedative drug during colonoscopy. in this study we analyzed the adverse effects of propofol (i.e., hemodyânamic and respiratory) on patients who underwent colonoscopies. me t hod s this study was performed in qom province, iran. in this study, 125 patients (63 females, 62 males) were enrolled. study patients were administered (0.5-1.5 mg/kg) intravenous prop...
متن کاملmeasurement of intraocular pressure using schiotz vs tono-pen tonometers in patients with primary congenital glaucoma
purpose: to compare the tono-pen and schiotz tonometers in measurement of intraocular pressure (iop) in patients with primary congenital glaucoma. methods: this study was conducted on 38 eyes of 20 patients with primary congenital glaucoma. all measurements were performed under general anesthesia. one minute after receiving halothane 3% iop was determined by tono-pen and then by schiotz tonomet...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Re-evaluation of the Schiotz tonometer calibration.
The calibration scale for the Schi0tz tonometers toas tested by comparing Goldmann applanation and Schi0tz measurements on the eyes of 906 patients. The study differed from several previous studies in that both the applanation and Schi0tz measurements were made with the subjects lying on their backs, thus eliminating errors due to change in intraocular pressure as the subject changed from one p...
