PURPOSE The corneal epithelium is essential for maintaining corneal transparency, and efforts have been made to develop improved techniques for corneal epithelial transplantation in patients with total limbal failure. We evaluated the suitability of transplanted cultivated human conjunctival epithelium (HCjE) as a corneal epithelium replacement in rabbits(More)
PURPOSE The ocular surface is covered by two biologically distinct epithelia: corneal and conjunctival. The expression of keratin12 (K12) is currently considered a hallmark of cornea-type differentiation. In the current study, the biological features of K12-positive cells in human bulbar conjunctival epithelium were examined. METHODS Human conjunctival(More)
PURPOSE To evaluate cell death in human donor corneas stored at 4 degrees C, to determine whether terminal deoxynucleotidyl transferase-mediated dUTP-fluorescein nick-end labeling (TUNEL) discriminates between apoptosis and necrosis in corneas stored at 4 degrees C. METHODS Ten human corneas were stored in Optisol (Chiron Ophthalmics, Irvine, CA) at 4(More)
PURPOSE To determine the feasibility of cultivated conjunctiva as a viable epithelial sheet for transplantation and corneal resurfacing in eyes with limbal stem cell deficiency (LSCD). METHODS Human corneal epithelial (HCE) and human conjunctival epithelial (HCjE) cells were cultivated on human amniotic membrane (AM) to confluence and then air lifted to(More)
PURPOSE We determined whether functional visual acuity (VA) parameters and a dry eyes (DEs) symptoms questionnaire could predict DEs in a population of visual terminal display (VDT) users. METHODS This prospective study included 491 VDT users from the Osaka Study. Subjects with definite DE, diagnosed with the presence of DE symptoms, tear abnormality(More)
PURPOSE To date, no studies have elucidated the composition of the corneal filament in detail. In this study, an immunohistochemical technique was used to clarify the exact composition of the corneal filament in filamentary keratitis. In addition, the mechanisms responsible for filament formation were identified. METHODS Filaments were obtained from 13(More)
IMPORTANCE Dry eye disease has become an important health problem. A lack of concordance between self-reported symptoms and the outcome of dry eye examinations has raised questions about dry eye disease. OBJECTIVE To explore the association between subjective happiness and objective and subjective symptoms of dry eye disease. DESIGN The study adopted a(More)
The first aim of this study was to clarify whether cigarette smoking affects tear secretion, goblet cell density, and tear MUC5AC concentration. The second purpose was to evaluate the correlations of conjunctival goblet cell density with tear MUC5AC concentration and other ocular surface evaluation factors. This cross-sectional study included 88 office(More)
Purpose. To assess the association of dry eye disease (DED) with physical activity and sedentary behavior. Methods. The cross-sectional survey conducted included Japanese office workers who use visual display terminals (n = 672). DED was assessed according to the Japanese Dry Eye Diagnostic Criteria, and participants were categorized into "definite DED,"(More)
