Influence of topical anaesthetics on Corneal Topography

open access: yesОфтальмохирургия, 2013
Introduction. By now it is a well-established fact that topical anaesthetics have an influence on IntraOcular pressure. The topical anaesthetic will give a lower intraocular pressure reading.

Changes in preoperative corneal measurements following same-day intraocular pressure testing with rebound tonometry

open access: yesTherapeutic Advances in Ophthalmology, 2020
Purpose: To evaluate the extent to which rebound tonometry affects corneal surface properties and preoperative corneal measurements. Setting: Four cornea specialty private practices. Design: Prospective case series.

A discrete-to-continuum model for the human cornea with application to keratoconus [PDF]

open access: yesarXiv, 2023
We introduce a discrete mathematical model for the mechanical behaviour of a planar slice of human corneal tissue, in equilibrium under the action of physiological intraocular pressure (IOP). The model considers a regular (two-dimensional) network of structural elements mimicking a discrete number of parallel collagen lamellae connected by proteoglycan-

Evidence on the Use of Topical Ciclosporin for Ocular Surface Disease: A Systematic Review and Meta‐Analysis

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To identify evidence on the use of topical CsA for ocular surface diseases (OSD). Methods A literature search was conducted following the preferred reporting items for systematic reviews and meta‐analyses (PRISMA) through June 2023 via Cochrane Central Registries, Clinical Trials Registry, Grey literature and citation searching ...

Analysis of corneal morphologic and pathologic changes in early-stage congenital aniridic keratopathy

open access: yesInternational Journal of Ophthalmology, 2017
AIM: To determine typical corneal changes of congenital aniridic keratopathy (CAK) using corneal topography and confocal systems, and to identify characteristics that might assist in early diagnosis.

Synchronous phase-demodulation of concentric-rings Placido mires in corneal topography and wavefront aberrometry (theoretical considerations) [PDF]

open access: yesarXiv, 2012
This paper presents a digital interferometric method to demodulate Placido fringe patterns. This method uses a computer-stored conic-wavefront as reference carrier. Even though, Placido mires are widely used in corneal topographers. This is not however a paper on corneal topography and/or its clinical use.

Critical taxonomic revision of Korean Dictyoteae describing three new species and honoring Haenyeo culture

open access: yesJournal of Phycology, EarlyView.
Abstract This study re‐evaluates the species diversity and taxonomy of the genera Canistrocarpus, Dictyota, and Rugulopteryx in Korea using an integrative approach combining molecular data and morphological observations. Phylogenetic analyses based on psbA, cox1, and rbcL gene sequences identified nine lineages including eight Dictyota and one ...

Exposing GAN-generated Faces Using Inconsistent Corneal Specular Highlights [PDF]

open access: yesarXiv, 2020
Sophisticated generative adversary network (GAN) models are now able to synthesize highly realistic human faces that are difficult to discern from real ones visually. In this work, we show that GAN synthesized faces can be exposed with the inconsistent corneal specular highlights between two eyes.

Comparison of Surgically-induced Astigmatism using Topography and Keratometry in Patients undergoing Phacoemulsification and Small Incision Cataract Surgery: A Prospective Interventional Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research
Introduction: Topographic measurement of corneal astigmatism is the current standard of care because, in addition to measuring corneal astigmatism, it identifies irregular astigmatism, which may limit optimum surgical results.
