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

Archives 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 ...

Biocompatibility of the Polymer Poly(Butylene Adipate‐Co‐Terephthalate) in the Cornea of Rabbits

Journal of Applied Polymer Science, EarlyView.
The biocompatibility of the PBAT in the rabbit cornea was evaluated through clinical assessment and histopathological analysis using hematoxylin and eosin, picrosirius red, and Masson’s trichrome staining. ABSTRACT In a novel approach to corneal biomaterials, this study evaluated the biocompatibility of heat‐pressed poly(butylene adipate‐co ...

Cost–benefit analysis of screening programme for diabetic retinopathy in Bulgaria

British Journal of Clinical Pharmacology, EarlyView.
Aims Late‐diagnosed diabetic retinopathy (DR) is difficult and expensive to treat. Screening programmes can identify the disease early and reduce the costs of its future treatment. This study aims to analyse the cost–benefit of screening programmes for DR.

Harmonizing NAD+ metabolism with CeMOF nanozyme to orchestrate intraocular pressure modulation for glaucoma treatment

VIEW, EarlyView.
Our findings demonstrate that NAD+ metabolism dysregulation contributes to elevated intraocular pressure in glaucoma. Supplementation with NAD+ precursors reduces IOP by alleviating oxidative stress, cellular senescence, and extracellular matrix deposition.

Ivermectin‐induced blindness in a Jack Russell terrier dog: Diagnosis and monitoring with electroretinography and chromatic pupillary light reflexes

Veterinary Record Case Reports, EarlyView.
Abstract A 4‐year‐old, neutered, female Jack Russell terrier presented with acute blindness, tremors, ataxia and rotatory nystagmus. Ophthalmic examination revealed absent menace response, dazzle reflex and pupillary light reflex, along with vermiform retinal lesions bilaterally.

Tonometry by Ocular Response Analyzer in Keratoconic and Warpage Eyes in Comparison with Normal Eyes

Journal of Current Ophthalmology, 2021
Purpose: To compare intraocular pressure (IOP) values measured by ocular response analyzer (ORA) in contact lens-induced corneal warpage, normal, and keratoconic eyes. Methods: In a prospective, observational case–control study, 94 eyes of 47 warpage-suspected cases and 46 eyes of ...

Quality of life and participation after corneal transplantation and potential predictors: A multicenter prospective cohort study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the long‐term effect of corneal transplantation on health‐ and vision‐related quality of life, visual functioning, and societal participation, and to assess potential predictors. Methods We conducted a multicenter prospective cohort study in 11 Dutch hospitals and eye clinics.

Tonographic Effect of Ocular Response Analyzer in Comparison to Goldmann Applanation Tonometry

PLOS ONE, 2017
The tonographic effect is a phenomenon of intraocular pressure (IOP) reduction following repeated tonometry. This study examines whether the tonographic effect occurs following IOP measurement performed with Ocular Response Analyzer (ORA).Both eyes of 31 glaucoma patients and 35 healthy controls underwent nine IOP-measurements performed with GAT and ...
