Ocular examination findings and measurements of tear production and tonometry of ring-tailed coatis (nasua nasua).

Veterinary Ophthalmology, 2021
OBJECTIVE To describe ocular anatomical features and to determine tear production and tonometry in normal anesthetized ring-tailed coati (Nasua nasua). ANIMALS Eight male and seven female ring-tailed coatis (30 eyes) were evaluated, with ages ranging ...

System Identification Approach to Ocular Tactile Tonometry

Volume 5: Biomedical and Biotechnology, 2023
Abstract Frequent intraocular pressure (IOP) measurements are necessary for the diagnosis and management of glaucoma. Most current tonometers utilize some form of corneal deformation in order to estimate the IOP. Trans-corneal tonometers require sterile parts, or are complex and expensive (air-puff tonometer).

The Relationship Between Corvis ST Tonometry Parameters and Ocular Response Analyzer Corneal Hysteresis

Journal of glaucoma, 2020
Precis: Corvis ST Tonometry and Ocular Response Analyzer (ORA) measurements were conducted in primary open-angle glaucoma and normative subjects. Many parameters were significantly correlated, however, the strengths were weak to moderate.

Ocular Rigidity and Tonometry

2021
There are many ways to measure the intraocular pressure (IOP) and all are influenced to some degree by the individual characteristics of the eye. Ocular rigidity (OR) is a familiar concept used in ophthalmology to describe the relationship between pressure and volume changes in the eyeball. This concept partly explains why IOP measurements vary between

Comparison of Biomechanically Corrected Intraocular Pressure Obtained by Corvis ST and Goldmann Applanation Tonometry in Patients With Open-angle Glaucoma and Ocular Hypertension

Journal of glaucoma, 2019
Supplemental Digital Content is available in the text. Precis: Biomechanically corrected intraocular pressure (bIOP) measurements provided by the new Corvis ST (CST) were higher than measurements obtained with Goldman applanation tonometry (GAT) in eyes ...

Central Corneal Thickness, Tonometry, and Ocular Dimensions in Glaucoma and Ocular Hypertension

Journal of Glaucoma, 2001
To assess possible correlations between central corneal thickness, tonometry, and ocular dimensions.One hundred seventeen eyes of 117 patients who were not taking any intraocular pressure-lowering medications were studied prospectively. Forty-one patients had ocular hypertension; 13 patients had primary open-angle glaucoma; and 10 patients had normal ...

Comparison Between Ocular Biometric Parameters and Intraocular Pressure With and Without Contact Lenses

Eye & contact lens, 2023
Objectives: To compare the values of central corneal thickness, anterior chamber depth (ACD), lens thickness (LT), vitreous length (VL), axial length (AL), and corneal-compensated intraocular pressure performed with and without contact lenses (CL ...

Comparing dynamic contour tonometry to Goldmann and hand-held tonometry in normal, ocular hypertension, and glaucoma populations

Annals of Ophthalmology, 2007
We prospectively compared dynamic contour tonometry (DCT) to Goldmann (GAT) and hand-held tonometry (HHT) in normal, ocular hypertension, and glaucoma populations. Both measurements were made on each patient within a 5-minute period during routine office exams over 4 months.

Experimental and Numerical Analysis of Ocular Tactile Tonometry

Volume 2: Biomedical and Biotechnology, 2012
This article describes the experimental and numerical analysis of a novel trans-scleral tonometer based on the use of an instrumented form of digital palpation tonometry. Similar to manual digital palpation tonometery (estimation of the eye pressure via tactile touch), the novel ocular tactile tonometer utilizes multiple force probes to gather force ...
