High sampling resolution optical coherence tomography reveals potential concurrent reductions in ganglion cell‐inner plexiform and inner nuclear layer thickness but not in outer retinal thickness in glaucoma

open access: yesOphthalmic and Physiological Optics, Volume 43, Issue 1, Page 46-63, January 2023., 2023
Abstract Purpose To analyse optical coherence tomography (OCT)‐derived inner nuclear layer (INL) and outer retinal complex (ORC) measurements relative to ganglion cell‐inner plexiform layer (GCIPL) measurements in glaucoma. Methods Glaucoma participants (n = 271) were categorised by 10‐2 visual field defect type.

Intraocular pressure monitoring by rebound tonometry in children with myopia

open access: yesTaiwan Journal of Ophthalmology, 2017
Background/Purpose: Topical atropine treatment is generally accepted to retard the progression of myopia, but it is associated with side effects such as photophobia and elevation of intraocular pressure (IOP). IOP measurements in children are challenging.

Dynamics of Droplet Generation from Corneal Tear Film during Non-contact Eye Procedure in the Context of COVID-19 [PDF]

open access: yes, 2020
Non-invasive medical diagnostics demonstrate a propensity for droplet generation and should be studied to devise risk mitigation strategies against the spread of the SARS-CoV-2 virus. We investigate the air-puff tonometry, which uses a short-timed air-puff to applanate the human eye in a bid to detect the early onset of glaucoma by measuring the ...

Red-free light in applanation tonometry [PDF]

open access: yesBritish Journal of Ophthalmology, 1999
Editor,—Goldmann’s applanation tonometry is generally performed using cobalt blue filter and fluorescein in order to obtain accurate localisation of the apex of the tear meniscus.1 2 The peak transmission value of the cobalt blue filter BG12 on the Haag–Streit slit lamp 900 BM is 0.80 at 400 nm, whereas that of the red-free filter BG39 is 0.965 at 490 ...

Future Research Perspective on the Interfacial Physics of Non-Invasive Glaucoma Testing in Pathogen Transmission from the Eyes [PDF]

open access: yesarXiv, 2023
Non-contact Tonometry (NCT) is a non-invasive ophthalmologic technique to measure intraocular pressure (IOP) using an air puff for routine glaucoma testing. Although IOP measurement using NCT has been perfected over many years, various phenomenological aspects of interfacial physics, fluid structure interaction, waves on corneal surface, and pathogen ...

Accuracy of Schiotz Tonometry in Measuring the Intraocular Pressure After Corneal Refractive Surgery

open access: yesJournal of Optometry, 2008
Purpose: To test the accuracy of Schiotz tonometry (ST) in patients that underwent photorefractive keratectomy (PRK). Methods: 175 eyes previously treated with PRK for myopia, myopic astigmatism or mixed astigmatism, with a mean preoperative spherical ...

Comparison of Goldmann applanation tonometry, rebound tonometry and dynamic contour tonometry in normal and glaucomatous eyes [PDF]

open access: yesInternational Journal of Ophthalmology, 2015
AIM: To compare the intraocular pressure (IOP) measurements obtained with the rebound tonometry (RT), dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) in normal and glaucomatous eyes and investigate the effects of central corneal ...

Reutilization of disposable rebound tonometer probes: Risk or return?

open access: yesIndian Journal of Ophthalmology, 2023
Purpose: An advantage of rebound tonometry (RT) is its ease of use so that it can also be operated by health care technicians. However, the cost of the disposable measuring probes is high and their reuse carries the risk of infection.

Different methods for measuring intraocular pressure [PDF]

open access: yesHalo 194, 2019
Tonometry is a method for measuring intraocular pressure (IOP). Goldmann applanation tonometry (GAT) represents a golden standard for measuring IOP. The measurement is conducted by measuring the force needed to straighten out a certain area of the cornea.
