PURPOSE To obtain descriptive statistics of central corneal thickness (CCT) in a large population of normal eyes undergoing refractive surgery and study the relationship of 2 variables, age and refraction, with CCT. SETTING Cornea and Laser Eye Institute, Hersh Vision Group, Teaneck, NJ. METHODS The CCT of 5158 patients was measured using an ultrasound pachymeter. Age and preoperative spher...

OBJECTIVE To determine mean change in visual acuity, central corneal thickness and symptoms in patients with pseudophakic bullous keratopathy after treatment with corneal collagen crosslinking. METHODS This quasi experimental study was conducted at Armed Forces Institute of Ophthalmology, Rawalpindi, Pakistan from April 2015 to Nov 2015. A total of 24 eyes of 24 patients were included in the ...

OBJECTIVE To investigate the central corneal thickness (CCT) in the central retinal vein occlusion fellow eye (CRVO-fellow eye) patients. MATERIAL AND METHOD A cross-sectional study with 97 CRVO-fellow eye patients and 112 healthy subjects. Three measurements of CCT were obtained with ultrasonic pachymetry. RESULTS Mean age of CRVO-fellow eye was higher than controls, 59.7 +/- 10.3 vs. 46.4...

Purpose To study the variations in corneal clinical biomechanical parameters (CCBP) and corneal geometrical parameters of rabbit in relation to age. Methods Rabbits aged 3, 7, 12, 18, and 24 months were enrolled. Each eye of the rabbits was tested with Ocular Response Analyzer (ORA), Optical Coherence Tomography (OCT), and Pachymeter to obtain the intraocular pressure (IOP): Goldmann-correlat...

PURPOSE To compare parameters of biomechanical response of the human cornea measured as corneal hysteresis (CH) and corneal resistance factor (CRF) in patients with diabetes mellitus and healthy control subjects. SETTING Department of Ophthalmology, Assaf Harofeh Medical Center, Zerifin, Israel. METHODS In the right eye of each participant, the CH, CRF, Goldmann-correlated intraocular press...

PURPOSE To evaluate the feasibility of anterior segment spectral domain optic coherence tomography (ASOCT) as rejection readout in a keratoplasty mouse model and to compare ASOCT against the current standard (i.e., a clinical score system). Furthermore, to compare both approaches with respect to intra- and inter-individual observer variability and to calculate a critical point that distinguishe...

Purpose: Comparison of the effect of selective laser trabeculoplasty (SLT) in glaucoma patients with high and low central corneal thickness (CCT). Materials and methods: Clinical trial on 72 glaucoma patients, controlled on medication that received SLT as replacement therapy. We compared the effect of SLT on patients with CCT ≥ 550 μm with patients having CCT <550 μm. Primary end point was intr...

Comment. The results suggest that in nonglaucomatous monkey globes, the CCT and the peripheral corneal thickness are not significantly correlated with the thickness of the lamina cribrosa in the center or at the periphery of the optic nerve head. They are also not associated with the thickness of the peripapillary sclera inside the optic nerve meninges or just outside the meninges. Confirming f...

AIM We performed a prospective, analytical study from 01 January to 31 March 2009 in the Ophthalmology Unit of the Gyneco-Obstetric and Pediatric Hospital of Yaounde, aiming to determine the profile of central corneal thickness (CCT) in the Cameroonian nonglaucomatous black population and its relationship with intraocular pressure (IOP). RESULTS AND DISCUSSION Four hundred and eighty-five pat...

To study effect of allergic conjunctivitis on central corneal thickness and intra ocular pressure. This was a case control which included 35 eyes 20 patients with compared age sex matched controls. Participants were subjected to complete ophthalmic examination including thickness(CCT) pressure(IOP) measured using ultrasound pachymeter goldmann’s applanation tonometer respectively. Comparision t...
