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 ...

The treatment of patients suffering from cerebral blindness following stroke is a topic of much recent interest. Several types of treatment are under investigation, such as substitution with prisms and compensation training of saccades. A third approach, aimed at vision restitution is controversial, as a proper controlled study design is missing. In the current study, 27 chronic stroke patients...

PURPOSE To assess the reproducibility of the ocular response analyzer (ORA) in nonoperated eyes and the impact of corneal biomechanical properties on intraocular pressure (IOP) measurements in normal and glaucomatous eyes. METHODS In the reliability study, two independent examiners obtained repeated ORA measurements in 30 eyes. In the clinical study, the examiners analyzed ORA and IOP-Goldman...

Several authors (Anderson and Grant, I973; Galin, Mclvor, and Magruder, I963; HetlandEriksen, I966; Kriegelstein and Langham, 1975a; Roberts and Rogers, I964; Tarkkanen and Leikola, I967) have reported that in normal subjects and in glaucomatous patients the intraocular pressure (IOP) in the supine position is about 2-5 mmHg higher than in the seated position. The measurements were carried out ...

PURPOSE To compare intraocular pressure (IOP) measurements, taken using Perkins applanation tonometry (PAT) and Goldmann applanation tonometry (GAT). METHODS 100 eyes of 100 patients underwent Perkins and Goldmann applanation tonometry, with a randomized order of modality, performed by a masked observer. The right eye was measured, for all subjects, and the data used in statistical analysis. ...

Background: Repeatability and validity are important components of precision in any measurement system. Aim: This study aimed to determine the effect change head neck position body posture on repeatability intraocular pressure (IOP) measurements with PT-100 non-contact tonometer compare Goldmann, Schiøtz readings. Setting: Optometry clinic, Saudi Arabia. Methods: The IOP was measured one select...

PURPOSE To investigate the underestimation of field loss in functional field score (FFS) between the Goldmann isopters III-4e and V-4e in visually impaired patients, in order to develop a predictive model for the FFS(III-4e) based on FFS(v-4e) that adjusts for possible confounders. Although the visual field is generally evaluated using Goldmann isopter III-4e, it has the disadvantage that not a...
