The aim of this study was to investigate the corneal alterations occurring in rheumatoid arthritis (RA) patients compared with healthy subjects and to define the presence of biomechanical alterations in cornea accompanying dry eye disease, the most common ocular manifestation of RA. Forty-seven RA patients and 40 control cases without any known systemic or ocular diseases were included in this ...

PURPOSE To assess variations in the biomechanical properties and central corneal thickness (CCT) throughout the female menstrual cycle. SETTING Department of Ophthalmology, Assaf Harofeh Medical Center, Zerifin Israel. DESIGN Case series. METHODS Young healthy women were prospectively recruited. Every participant was assessed at the beginning of the menstrual cycle, at ovulation, and at t...

PURPOSE To evaluate the effect of prostaglandin analogs (PGAs) on the biomechanical properties (corneal hysteresis [CH], corneal resistance factor [CRF]) and central corneal thickness (CCT) of patients with open-angle glaucoma. METHODS A total of 108 eyes were prospectively included for repeated measurements of intraocular pressure (IOP) with Goldmann applanation tonometry (GAT) and ocular re...

BACKGROUND/AIM To investigate age-related changes in intraocular pressure (IOP) and biomechanical parameters of the cornea in healthy subjects. MATERIALS AND METHODS There were 404 healthy subjects included prospectively in this study. The subjects were divided into 3 groups (Group 1:93 subjects aged < 18, Group 2:189 subjects aged between 18 and 59, and Group 3:122 subjects aged ≥ 60). Corne...

PURPOSE The purpose of the study was to determine the accuracy of intraocular pressure (IOP) measurement after small incision lenticule extraction (SMILE) using Goldmann applanation tonometry (GAT) and ocular response analyzer (ORA). METHODS This is a prospective clinical study that was conducted on 30 eyes in the interval between February 2016 and September 2016. The age of the patients rang...

BACKGROUND To investigate the biomechanical properties of the cornea measured with the Ocular Response Analyzer (ORA) and their association with the anterior segment parameters representing the geometric dimensions including the corneal volume and anterior chamber volume. METHODS A retrospective review of 1020 patients who visited the BGN Eye Clinic was done. The mean radius of the corneal cu...

Purpose: To compare and assess the ability of pressure-derived parameters and corneal deformation waveform signal-derived parameters of the ocular response analyzer (ORA) measurement to distinguish between keratoconus and normal eyes, and to develop a combined parameter to optimize the diagnosis of keratoconus. Materials and methods: One hundred and seventy-seven eyes (177 patients) with kerato...

PURPOSE To assess the biomechanical properties of corneas in patients with normal tension glaucoma (NTG) and to compare them with those of patients with primary open-angle glaucoma (POAG), ocular hypertension (OHT), and normal controls (N). METHODS Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann intraocular pressure (IOPg), and corneal compensated IOP (IOPcc) were obtained ...

Keratinocyte growth factor-2 (KGF-2), also called fibroblast growth factor-10 (FGF-10), is a member of the fibroblast growth factor family. It plays a critical role in epithelial development and exerts its biological activities in a paracrine manner on the receptor FGFR2-IIIb. This study examined the function of topically applied KGF-2 in vivo on wound healing using a CO(2) laser, corneal epith...

purpose : to compare intraocular pressure (iop) readings measured by the ocular response analyzer (ora) with those measured by the goldmann applanation tonometer (gat) in keratoconic eyes following penetrating keratoplasty (pkp) and evaluate the influence of anatomical and biomechanical properties of the grafts on the iop measurements methods : in this cross-sectional study conducted on 45 kera...
