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...

This is a descriptive study designed to assess the predictive value of intraocular pressure (IOP) measurement in GPs' offices in an urban healthcare site using Tono-pen XL. A total of 2044 patients, aged > or =40 years, were enrolled by consecutive sampling from patients visiting the GP. Those participants who had IOP > or =21 mmHg were referred to the ophthalmologist. Of the 226 then tested, o...

OBJECTIVES This study was designed to determine noninvasively the age-associated changes in regional mechanical properties in normals using phase-contrast magnetic resonance imaging (PCMRI). BACKGROUND It has been well documented that there is a progressive increase in aortic pulse wave velocity (PWV) with age. Previously, PWV has been measured at a single aortic location, or has compared art...

PURPOSE To compare the reliability and accuracy of intraocular pressure (IOP) measured while wearing soft contact lenses (SCLs) using a non-contact tonometer (NCT), Goldmann applanation tonometer (GAT), iCare rebound tonometer (RBT) and the Tono-Pen XL. METHODS Twenty-six healthy subjects were examined. The IOP was measured using NCT, GAT, RBT, and the Tono-Pen XL, while the subjects wore SCL...

The accuracy of intraocular pressure measurement with the minified Goldmann applanation tonometer, the pneumatonometer, and the Tono-Pen tonometer were compared in post-mortem human eyes which had undergone penetrating keratoplasty. Enucleated post-mortem human eyes underwent same sized (7.75 mm) or 0.5 mm oversized (8.25 mm) autologous penetrating keratoplasty. Intraocular pressure was then se...

• Micro-scale surgery requires a very technically advanced skill set, including high hand-eye coordination and little-tono hand tremor. • To improve microsurgical procedures, such as vein suturing, we have developed tools for the REMS, a cooperativelycontrolled surgical robot that reduces tremor when operating. • Our goal is to design effective needle holders and validate the use of the REMS by...
