24-h Efficacy of Glaucoma Treatment Options [PDF]

open access: yes, 2016
Current management of glaucoma entails the medical, laser, or surgical reduction of intraocular pressure (IOP) to a predetermined level of target IOP, which is commensurate with either stability or delayed progression of visual loss.

Retinal oxygen saturation and retinal vessel diameter in glaucoma patients before and after trabeculectomy

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To compare retinal vessel oxygen saturations and diameters before, 1 and 3 months after trabeculectomy. Methods Retinal oxygen saturations and vessel diameters were obtained using retinal oximetry. The effect of the postoperative intraocular pressure (IOP) decrease on the arteriovenous difference (AV‐difference) was evaluated ...

Increased Ocular Pulse Amplitude Associated with Unilateral Dysgenesis of the Orbital Roof

open access: yesCase Reports in Ophthalmology, 2015
Introduction: Two patients (one with neurofibromatosis type 1) presented with unilateral ocular pulsation. Methods: A CT scan of the orbits revealed extensive dysgenesis of the orbital roof with herniation of the frontal lobe into the orbit in both cases.

Evaluation of a new rebound tonometer for self-measurement of intraocular pressure [PDF]

open access: yes, 2015
Background/aims To compare the accuracy of self-obtained, partner-obtained and trainer-obtained measurements using the handheld Icare Home rebound tonometer with Goldmann applanation tonometry (GAT), and to evaluate the acceptability to subjects of ...

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

open access: yesActa Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Intraocular pressure in a cohort of healthy Eastern European schoolchildren: variations in method and corneal thickness [PDF]

open access: yes, 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

Ocular Pulse Amplitude in Healthy Subjects as Measured by Dynamic Contour Tonometry [PDF]

open access: yesArchives of Ophthalmology, 2006
To test whether dynamic contour tonometry yields ocular pulse amplitude (OPA) measurements that are independent of corneal thickness and curvature, and to assess variables of observer agreement.In a multivariate cluster analysis on 223 eyes, the relationship between central corneal thickness, corneal curvature, axial length, anterior chamber depth ...

Variation in measuring and ophthalmic factors correlating with central corneal thickness in the Northern Finland birth cohort eye study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To assess the correlation between optical coherence tomography (OCT) and ultrasound pachymetry (USP) as methods for analysing central corneal thickness (CCT) and to evaluate ophthalmic factors affecting CCT. Methods The eyes of 3070 subjects of the Northern Finland Birth Cohort (NFBC) were examined at the age of 45–49 years.

The usefulness of CorvisST Tonometry and the Ocular Response Analyzer to assess the progression of glaucoma [PDF]

open access: yesScientific Reports, 2017
AbstractCorneal Visualization Scheimpflug Technology (CST) and Ocular Response Analyzer (ORA) measurements were carried out in 105 eyes of 69 patients with primary open-angle glaucoma. All patients had axial length (AL), central corneal thickness (CCT), intraocular pressure (IOP) with Goldmann applanation tonometry (GAT) and eight visual fields (VF)s ...

Reduced order modelling of air‐puff test for corneal material characterisation

open access: yesJournal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.
