Ophthalmic 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.

Corneal tissue changes following short‐term soft contact lens wear of different materials
Ophthalmic and Physiological Optics, Volume 43, Issue 1, Page 35-45, January 2023., 2023 Abstract Purpose To study the effect of different soft contact lens (CL) materials during short‐term wear on corneal tissue. Methods Twenty‐two healthy participants wore both silicone hydrogel (MyDay, CooperVision) and hydrogel soft CLs (Biomedics 1 day extra, CooperVision) for 8 h per lens.

Intraocular pressure in a cohort of healthy Eastern European schoolchildren: variations in method and corneal thickness [PDF]
, 2012 BACKGROUND: Intraocular pressure (IOP) in the developing eye of a child is not always easy to measure and there is no technique that is known to be the most accurate for the young eye. Measurements are needed on many cohorts of children with different

Comparison of IOP obtained in different kind of eyes with contact and no contact tonometers
Oman Journal of Ophthalmology, 2022 BACKGROUND: The aim of this study is to analyze and compare the intraocular pressure (IOP) values measured in three different kinds of participants such as healthy subjects (HS), keratoconus patients (KP), and those who underwent myopic photorefractive ...

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

Uncertainty propagation and sensitivity analysis: results from the Ocular Mathematical Virtual Simulator [PDF]
, 2021 We propose an uncertainty propagation study and a sensitivity analysis with the Ocular Mathematical Virtual Simulator, a computational and mathematical model that predicts the hemodynamics and biomechanics within the human eye. In this contribution, we focus on the effect of intraocular pressure, retrolaminar tissue pressure and systemic blood pressure

Feeling the pressure: a cross-sectional study exploring feasibility of a healthcare Pop-Up for intraocular pressure measurements in shopping centres in England [PDF]
, 2019 OBJECTIVES: To test the hypothesis that a shopping centre Pop-Up health check combining an intraocular pressure (IOP) check with a general health check (blood pressure (BP)) is more readily accepted by the general public than an IOP check only.

Gaze-Contingent Ocular Parallax Rendering for Virtual Reality [PDF]
ACM Trans. Graph. 39, 2, Article 10 (April 2020), 12 pages, 2019 Immersive computer graphics systems strive to generate perceptually realistic user experiences. Current-generation virtual reality (VR) displays are successful in accurately rendering many perceptually important effects, including perspective, disparity, motion parallax, and other depth cues.
