PURPOSE The chemical coding of intrinsic choroidal neurons (ICNs) has features in common with extrinsic fibers (e.g., from the pterygopalatine ganglion) making it impossible to assess whether a neuronal nitric oxide synthase (nNOS)/vasoactive intestinal polypeptide (VIP)-immunoreactive nerve fiber is of intrinsic or extrinsic origin. Neurobiotin injections(More)
PURPOSE To provide a detailed assessment of the techniques, technical features, and practical use of 6 aberrometers made available to our institution from September 2002 to January 2004. SETTING Department of Ophthalmology, University Hospital Antwerp, Antwerp, Belgium. METHODS A number of technical and practical parameters are listed for the Visual(More)
PURPOSE To describe the normative data for corneal Scheimpflug densitometry based on a cohort of normal participants. METHODS A total of 445 healthy participants were recruited for assessment (794 eyes). Left and right eyes were considered separately. All participants were assessed using the corneal densitometry analysis add-on to the standard software of(More)
PURPOSE To determine the dependency of straylight on ocular biometry. METHODS This prospective study included 518 eyes of 277 volunteers of diverse ethnic backgrounds with healthy eyes of various iris colors. The eyes had retinal straylight tested using a commercial psychophysical device. Ocular axial length and refraction were also measured with an(More)
UNLABELLED Management of the posterior capsule significantly affects the outcome of pediatric cataract surgery. Posterior capsule opacification (PCO) is rapid and virtually inevitable in very young children when adult-style cataract surgery is performed and the posterior capsule is left intact. In eyes with pediatric cataract, primary posterior capsulotomy(More)
To determine if a standardized, non-xenogenic, reduced manipulation cultivation and surgical transplantation of limbal stem cell grafts is a safe and effective treatment option for patients with total and partial limbal stem cell deficiency. In vitro cellular outgrowth and phenotype of the limbal epithelial cell and composite grafts were validated using a(More)
PURPOSE The purpose of this article was to present methods capable of estimating the size and shape of the human eye lens without resorting to phakometry or magnetic resonance imaging (MRI). METHODS Previously published biometry and phakometry data of 66 emmetropic eyes of 66 subjects (age range [18, 63] years, spherical equivalent range [-0.75, +0.75] D)(More)
PURPOSE To create a binocular statistical eye model based on previously measured ocular biometric data. METHODS Thirty-nine parameters were determined for a group of 127 healthy subjects (37 male, 90 female; 96.8% Caucasian) with an average age of 39.9 ± 12.2 years and spherical equivalent refraction of -0.98 ± 1.77 D. These parameters described the(More)
PURPOSE To evaluate the clinical and epidemiological aspects of contact lens-related infectious corneal ulcers requiring hospitalization. METHODS A retrospective analysis was performed on the files of patients hospitalized for contact lens-induced corneal ulcer in the eight Belgian university hospitals over a 7-year period (January 1997 to December 2003).(More)
PURPOSE Several reports have demonstrated an association between glaucoma and obstructive sleep apnea (OSA), though the origin of this association remains unknown. In the present study, the influence of OSA and continuous positive airway pressure (CPAP) therapy on intraocular pressure (IOP) and ocular perfusion pressure (OPP) was examined. METHODS IOP,(More)
