PURPOSE Polymorphisms in the interleukin 1 alpha (IL1A) and IL1B gene regions were previously associated with keratoconus in a Korean population. In the present study, we investigated whether the IL1A and IL1B polymorphisms are associated with keratoconus in a Japanese population. METHODS A total of 169 Japanese patients with keratoconus and 390 Japanese(More)
PURPOSE To demonstrate that interferon-gamma (IFN-gamma) is the key cytokine responsible for the upregulation of HLA-DR antigen in conjunctival epithelial cells of Sjogren syndrome (SS) patients. METHODS Flow cytometry of conjunctival epithelial cells from SS and non-SS dry eye patients was performed for the quantification of HLA-DR surface expression.(More)
OBJECTIVE The present study investigated the expression of ICAM-1 and VCAM-1 on fibroblasts with interleukin (IL)-4 and/or tumor necrosis factor (TNF)-alpha stimulation and assessed the effect of eosinophil adhesion on fibroblast viability. METHODS Primary cultured human corneal fibroblasts were incubated with IL-4, TNF-alpha, or their combination for 24(More)
PURPOSE To determine the suppressive effects of antibodies (Abs) against CC-chemokine receptor (CCR)-1 and CCR-3 on eosinophil chemotaxis induced by culture supernatant from corneal keratocytes and by tears from severely allergic patients with corneal ulcer. METHODS Primary cultures of human corneal keratocytes were incubated with interleukin (IL)-4 (33.3(More)
PURPOSE Tryptase that is released by mast cell degranulation has recently been thought to play a key role in wound healing in allergic bronchitis. Conjunctival fibroblasts secrete mediators and extracellular matrices that could exacerbate inflammation and papillary formation in allergic conjunctivitis. This study was conducted to investigate the effect of(More)
PURPOSE To prospectively evaluate the effect of controlled adverse chamber environment (CACE) exposure on tear function, including tear osmolarity, in subjects wearing narafilcon A versus those wearing etafilcon A soft contact lens (SCL). METHODS Thirty-one healthy subjects with no history of contact lens wear (13 women, 18 men; average age, 30.5 ± 6.5(More)
PURPOSE To elucidate the status of the conjunctival inflammation in atopic keratoconjunctivitis (AKC) using laser scanning confocal microscopy and compare the relevant findings with conjunctival brush cytology in a prospective controlled study. METHODS Twenty eyes from 20 AKC patients as well as 16 eyes from 16 age and sex matched normal subjects were(More)
BACKGROUND Although the oxidative stress status in atopic skin disease has been reported to be elevated, there are still no studies related to the status of oxidative stress in atopic ocular surface disease. The purpose of this study was to evaluate the ocular surface lipid oxidative stress status and inflammation in atopic keratoconjunctivitis (AKC)(More)
Purpose. This study examined the association between the severity of visual field defects and the prevalence of motor vehicle collisions (MVCs) in subjects with primary open-angle glaucoma (POAG). Methods. This is a cross-sectional study. Japanese patients who have had driver's licence between 40 and 85 years of age were screened for eligibility.(More)
In a previous study, we demonstrated that topical D-beta-hydroxybutyrate ameliorates corneal epithelial erosion and superficial punctate keratopathy in a rat model of dry eye disease. In the current investigation, we performed a prospective, randomized, multicentre, double-blind, placebo-controlled study to assess the safety and efficacy of 1%(More)
