BACKGROUND Variants in the complement cascade genes and the LOC387715/HTRA1, have been widely reported to associate with age-related macular degeneration (AMD), the most common cause of visual impairment in industrialized countries. METHODS/PRINCIPAL FINDINGS We investigated the association between the LOC387715 A69S and complement component C3 R102G risk(More)
PURPOSE To analyze the in vivo morphology of the different corneal sublayers and corneal nerves in primary Sjögren's syndrome (SS). METHODS Ten eyes of 10 patients with primary SS and 10 eyes of 10 sex- and age-matched control subjects were investigated. Diagnosis was based on American-European consensus criteria. In vivo confocal microscopy with(More)
PURPOSE To examine human corneal morphology and nerve recovery 5 years after photorefractive keratectomy (PRK). METHODS Fourteen eyes of 14 patients (ages, 27-53 years) who underwent 6-mm diameter PRK for low to moderate myopia (spherical equivalent [SE] -2.5 to -8.0 D) were examined once 5 years after surgery. Nine healthy individuals served as control(More)
Understanding of corneal wound healing plays an important role, not only in management of corneal infections, but especially in refractive surgery. A better control of wound healing mechanisms might improve the results of such resculpturing techniques and help to avoid complications arising from these procedures. While studies have been focused in different(More)
PURPOSE A strong association of a Tyr402His polymorphism in the complement factor H (CFH) gene and a Met299Val polymorphism in the elongation of very long chain fatty acids-like 4 (ELOVL4) gene with age-related macular degeneration (AMD) has been identified in Caucasian populations in the United States. Earlier a Gln5345Arg variant in the hemicentin 1(More)
PURPOSE To describe the confocal microscopic findings, with special reference to corneal subbasal nerves, after herpes simplex virus (HSV) keratitis. METHODS In this study, 16 HSV eyes and 14 contralateral eyes of 16 patients, diagnosed with unilateral HSV keratitis 1-12 months earlier by the presence of dendritic corneal ulceration or microbiologic(More)
PURPOSE To evaluate the time course of changes in corneal sensitivity to mechanical and chemical stimuli produced by laser in situ keratomileusis (LASIK) in humans. METHODS We performed a cross-sectional study of 17 LASIK-operated eyes (VisX S2, equipped with version 2.50-3.10 software) and 15 control eyes of 17 individuals to evaluate regeneration of(More)
PURPOSE To evaluate the long-term effects of excimer laser treatment for ametropia after surgical treatment of rhegmatogenous retinal detachment (RRD) with scleral buckles. SETTING Helsinki University Eye Hospital, Helsinki, Finland. METHODS Ten patients (10 eyes) who had 1 or more surgeries for RRD followed by refractive surgery for myopia were(More)
PURPOSE Matrix metalloproteinases (MMPs) play a central role in the wound-healing process. The objective of this study was to identify and characterize the levels and molecular forms of human tear fluid collagenase-2 (MMP-8) and membrane type 1-MMP (MT1-MMP or MMP-14) in patients who had undergone excimer laser photorefractive keratectomy (PRK) and in(More)
We describe four patients who developed corneal erosion after an exposure to a pepper spray containing toxic carriers. Two of these patients were exposed to a pepper gas containing 5% oleoresin capsicum (OC) as an irritant and 92% trichlorethylene or unknown amount of dichloromethane as a carrier. One patient was exposed to a mock (containing 92%(More)
