THE Goldmann applanation tonometer (1954), as modified by Goldmann and Schmidt (1957), is becoming the standard instrument for measuring the intra-ocular pressure. The accepted method of preparing the eye for a pressure reading is to anaesthetize the cornea and then to stain the pre-corneal film with fluorescein (DukeElder, 1962). The disadvantage of this method is that it requires two manceuvr...

Identical specifications for size and luminance of the target and dome on four projection perimeters-Goldmann, Marco, Topcon, and Rodenstock- seemed to indicate that similar visual fields should be plottable with each instrument. We subjected 30 eyes to perimetry with all four machines. The Rodenstock perimeter was usually unable to map the central field with the I2e target and to identify the ...

PURPOSE To compare quantitatively visual field (VF) results obtained using a new standardized semiautomated kinetic perimetry (SKP) with those obtained by conventional Goldmann manual kinetic perimetry (MKP) in patients with advanced VF loss. DESIGN Prospective, single-center, observational comparative case series. SUBJECTS AND METHODS Seventy-seven eligible patients (36 suffering from adva...

PURPOSE The purpose of this study was to evaluate the fluctuation of intraocular pressure measurements obtained by Goldmann applanation tonometry, dynamic contour tonometry, and corneal compensated non-contact tonometry during office hours in glaucoma and healthy participants. This study also aims at correlating the intraocular pressure fluctuations with fluctuations of corneal hysteresis, cent...

months previously. An avidity of 40% is usually seen in infections acquired more than 6 months previously. The Goldmann-Witmer coefficient,3 the quotient of relative amounts of toxoplasmal antibodies in vitreous and serum, was 3*19:1. Baarsma et all consider a coefficient ofmore than 3 to be a positive result, consistent with localised active antibody production in the vitreous, suggesting acti...

background: to evaluate the agreement in intraocular pressure (iop) measurements by ocular response analyzer (ora) and tono-pen xl (txl) with the goldmann applanation tonometer (gat) and to examine corneal biomechanical properties in aphakic glaucoma patients with a central corneal thickness (cct) >600 µ. methods: thirty-six eyes of aphakic glaucoma patients (group 1) and 40 eyes of normal chil...
