PURPOSE To present full ophthalmologic examination and retinal nerve fiber layer (RNFL) photographs of autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) patients showing significant increases in RNFL thickness compared to healthy subjects, but without myelinated retinal fibers. METHODS The study design was observational case series. Ten eyes of five patients with molecular co...

PURPOSE To analyze the safety and efficacy of standard corneal collagen cross-linking (CXL) in advanced cases of progressive keratoconus after 4 years of follow-up. METHODS A retrospective case series of patients with advanced progressive keratoconus (stages 3 and 4 of Amsler-Krumeich classification) underwent standard CXL treatment. The parameters examined were changes in uncorrected visual ...

AIM To examine the occurrence of commonly known clinical signs of keratoconus (KC), i.e. Fleischer ring, prominent corneal nerves and thinning, among unaffected family members of KC patients and healthy control individuals. METHODS Data of both eyes of 117 relatives of KC patients having no manifest disease based on videokeratography indices (KC relatives), and 142 controls were used for Pear...

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 to evaluate the influence of anatomical and biomechanical properties of the grafts on iop measurements. methods: this cross-sectional study was conducted on 45 kerat...

OBJECTIVE To compare the reproducibility of measurements obtained with a new pachymetry instrument, the Topcon specular microscope (Topcon SP-2000P; Topcon America Corp, Paramus, NJ), with those obtained by ultrasound pachymetry. METHODS Corneal thickness was measured in 40 eyes of 40 patients 3 times each with the Topcon SP-2000P and an ultrasound pachymeter (DGH 500, DGH Technology Inc, Ext...

OBJECTIVE To study the central corneal thickness of a Spanish population group and determine the influence of age, gender, axial length and refractive error on central corneal thickness (CCT) values. METHODS An observational, cross-sectional, double masked study was conducted on 357 eyes of consecutive Caucasian patients without ophthalmic disease. They were distributed according to age, and ...

BACKGROUND The aim of this study was to evaluate central corneal thickness in patients with atopic keratoconjunctivitis. MATERIAL AND METHODS The study was conducted in the Atatürk University School of Medicine between April 2011 and June 2013. The study group included 60 eyes of 30 patients with atopic keratoconjunctivitis. Sixty eyes of 30 healthy individuals without any ophthalmic or syste...

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 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 safety and efficacy of Ferrara intrastromal corneal rings in the treatment of eyes with keratoconus without central corneal scarring. SETTING Vlemma Eye Institute, Athens, Greece. METHODS Twenty-six patients with bilateral keratoconus, clear central corneas, and contact lens intolerance participated in the study. Videokeratographic corneal topography and ultrasonic p...
