AIM To confirm the accuracy of the Pulsair 3000 before introducing the instrument into clinical practice. METHOD A masked study by two experienced tonometrists comparing the mean of the Goldmann intraocular pressure (IOP) readings against the Pulsair 3000 reading (average of four puffs). Results of 150 eyes were compared with an IOP range of 10 mm Hg-44 mm Hg. RESULTS Correlation between th...

AIMS The tonographic effect is a phenomenon of intraocular pressure (IOP) reduction following repeated tonometry. This study examines whether the tonographic effect occurs following IOP measurement performed with Ocular Response Analyzer (ORA). METHODS Both eyes of 31 glaucoma patients and 35 healthy controls underwent nine IOP-measurements performed with GAT and ORA. The number of GAT and OR...

PURPOSE To experimentally examine the effect of corneal modulus on Goldmann applanation tonometry (GAT) and Tono-pen (Tono-pen XL, Reichert, Inc., Depew, NY) measurements of intraocular pressure (IOP) in a canine eye model. METHODS Twenty-one canine globes were recovered from healthy animals. IOP was controlled at 10, 15, 20, 30, and 40 mm Hg and measured by GAT and Tono-pen following standar...

MANY ophthalmologists measure intra-ocular pressure with the Goldmann tonometer. It is neither portable nor capable of being used with the patient supine, which is disadvantageous in glaucoma screening programmes when it is often necessary to examine sick patients in their homes. An applanation tonometer, which is portable and can be used with the patient supine, sitting, or even standing, has ...

Background: To analyze the limits of agreement for the intraand inter-session measurements of intra-ocular pressure as measured by the Goldmann applanation tonometer and the Canon TX-F noncontact pulsair tonometer Methods: For this cross sectional study, 138 eyes of 138 cases of age > 16 years with no evidence of glaucomatous changes were recruited. Cases with astigmatism ≥ ±3.0 Diopters, corne...
