In the search for more accurate ways to determine intraocular pressure, the Halberg applanation tonometer may represent an alternative to the Schi0tz tonometer for routine screening pressure measurements. Although between 100 to 150 measurements are generally required to gain proficiency with the Halberg, the instrument is accurate in patients with normal corneas even with very abnormal scleral...

Dear Editor, The recent publication on “Pediatric Patients and Tonometers” is interesting.1 Eraslan et al.1 concluded that “Because Tono-Pen (TP) measurements were lower than Goldmann applanation tonometer (GAT) measurements and non-contact tonometer measurements ...

AIM To evaluate the intraocular pressure (IOP) measurements by Icare rebound tonometer over a contact lens in comparison with Goldmann applanation tonometry (GAT). METHODS Fifty patients using contact lens were included in this study. One of the eyes of the patients was selected randomly and their IOP were measured by rebound tonometer with and without contact lens (RTCL, RT respectively) and...

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...

Glaucoma is usually considered to be adequately controlled when Goldmann applanation readings are below 22 mmHg. It is, however, now known that the intraocular pressure increases to a varying degree when the patient changes his posture from sitting to a recumbent position (Galin, McIvor, and Magruder, I963; Roberts and Rogers, I964; Hetland-Eriksen, Ig66a; Inglima, I966; Tarkkanen and Leikola, ...

BACKGROUND The purpose of this study was to determine the accuracy of intraocular pressure (IOP) measurement after laser in situ keratomileusis (LASIK) or epithelial laser in situ keratomileusis (Epi)-LASIK using Goldmann applanation tonometry, air puff tonometry, ocular response analyzer corneal compensated IOP (ORA IOPcc) and Pentacam corrected IOP. METHODS A prospective comparative clinica...

IntroductionThe Goldmann Applanation Tonometer (GAT) is accepted as the gold standard tool to measure Intraocular Pressure (IOP). Besides, there an emerging Icare Rebound (RBT) which can be alternative in terms of measuring IOP.ObjectiveThis research aimed analyze agreement, and repeatability intraocular pressure (IOP) measurements compare outcomes RBT GAT among Mzuzu University Students Malawi...
