PURPOSE Corneal collagen crosslinking (CXL) is designed to halt the progression of keratoconus and corneal ectasia by inducing corneal stiffening. However, it currently is difficult to monitor and evaluate CXL outcome objectively due to the lack of suitable methods to characterize corneal mechanical properties. We validated noncontact Brillouin microscopy(More)
Anemia is a recognized feature of chronic disease and severe acute infection in hospitalized children. The purpose of this study was to determine the association of anemia with manifestations of infection in an unselected group of children seen as outpatients. The group consisted of 1347 children between the ages of 0.5 and 12 years that were seen over a(More)
PURPOSE Understanding corneal biomechanics is important to refractive or therapeutic corneal treatments. The authors studied the corneal response to variable intraocular pressure (IOP) in porcines eyes after UV collagen cross-linking (CXL), in comparison with untreated eyes. METHODS Twenty-three enucleated eyes were treated with standard CXL conditions(More)
A new technique is presented for the non-invasive imaging of the dynamic response of the cornea to an air puff inducing a deformation. A spectral OCT instrument combined with an air tonometer in a non-collinear configuration was used to image the corneal deformation over full corneal cross-sections, as well as to obtain high speed measurements of the(More)
PURPOSE Air puff systems have been presented recently to measure corneal biomechanical properties in vivo. In our study we tested the influence of several factors on corneal deformation to an air puff: IOP, corneal rigidity, dehydration, presence of sclera, and in vivo versus in vitro conditions. METHODS We used 14 freshly enucleated porcine eyes and five(More)
The aim of this prospective study was to determine the incidence of bronchopulmonary dysplasia (BPD) in and the outcome of neonates ventilated for respiratory distress syndrome (RDS). The study was conducted in a developing country prior to the use of surfactant replacement therapy and the results are compared to published reports from the developed world.(More)
PURPOSE Intrastromal corneal-ring segments (ICRSs) are applied to improve highly distorted vision in keratoconic, myopic, and astigmatic patients. Selections of ICRS geometry and position are primarily based on empirical nomograms. We developed a finite-element model (FEM) predicting the corneal response to different ICRS geometries in normal and(More)
Twenty-eight unselected premature infants were subjected to anorectal pressure studies, using an infusion manometric technique, with a view to establishing normal parameters in this age group. Satisfactory rectal and sphincter pressure readings were obtained in all but one case. In all of these there was a normal anorectal reflex. Low birth weight and(More)
PURPOSE To compare the stromal demarcation line depth in pulsed versus continuous corneal cross-linking (CXL) for keratoconus. METHODS Seventy eyes underwent epithelium-off cross-linking, with 0.1% riboflavin applied during 10 minutes prior to ultraviolet irradiation at 30 mW/cm2. Thirty-six eyes received pulsed irradiation (1 second on, 1 second off) for(More)
