purpose: to compare corneal biomechanical properties and intraocular pressure (iop) in eyes with pseudophakic bullous keratopathy (pbk) before and after descemet stripping automated endothelial keratoplasty (dsaek). methods: this prospective non-randomizedintrasubject comparative study was conducted on 44eyes of 22 patients with the diagnosis ofpbk who underwent dsaek in one eye.intraocular pre...

Purpose: To evaluate and compare corneal hysteresis (CH), resistance factor (CRF), central thickness (CCT), measurements were taken between a healthy population (controls), patients diagnosed with glaucoma (DG), suspect due to ocular hypertension (OHT), family history of (FHG), or glaucoma-like optic discs (GLD). Additionally, Goldmann-correlated intraocular pressure (IOPg) corneal-compensated ...

PURPOSE To evaluate corneal biomechanics with the Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments, Depew, NY) after penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK). SUBJECTS AND METHODS Sixty-three eyes of 63 patients were included in this prospective comparative study. Patients were divided into 3 groups: the first included 21 eyes of normal subjec...

Case report of a patient, with a thick cornea, for Fuchs dystrophy in its early stages, yet with preserved corneal transparency (subclinical corneal edema), associated with normal intraocular pressure (IOP) by Goldman applanation tonometry (GAT), which was however, the diagnosis of primary open-angle glaucoma on the basis of structural changes of the optic nerve. The tomographic study showed a ...

BACKGROUND The purpose of this study was to evaluate the effects of laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) on corneal biomechanical properties. METHODS We used the ocular response analyzer to measure corneal hysteresis (CH) and corneal resistance factor (CRF) before and after refractive surgery. RESULTS In all, 230 eyes underwent LASIK and 115 ey...

The neural capacity (NC) of high-pass resolution perimetry (HRP) was compared to the retinal nerve fiber layer thickness measured with the GDx Nerve Fiber Analyzer in 74 patients with either ocular hypertension or primary open-angle glaucoma at various stages of severity. A statistically significant correlation was found between the NC and the GDx ellipse average, the total polar integral, and ...

Background: Elevated intraocular pressure (IOP) is one of the most important factors for diagnosis and monitoring glaucoma. IOP currently only modifiable risk factor glaucoma, cornea transparent tissue covering front eye. It a powerful refracting surface, providing 2/3 eye's focusing power. The adult about 1/2 millimeter thick comprised 6 layers: epithelium, Bowman's membrane, stroma, Dua's lay...

background: to evaluate the agreement in intraocular pressure (iop) measurements by ocular response analyzer (ora) and tono-pen xl (txl) with the goldmann applanation tonometer (gat) and to examine corneal biomechanical properties in aphakic glaucoma patients with a central corneal thickness (cct) >600 µ. methods: thirty-six eyes of aphakic glaucoma patients (group 1) and 40 eyes of normal chil...
