Design: Cross-sectional, population-based study. All residents of Kumejima Island, Japan, located in southwestern Japan (eastern longitude, 126° 48'; northern latitude, 26° 20'), 40 years or older were asked to undergo a comprehensive questionnaire and ocular examination, including noncontact specular microscopy of corneal endothelial cells.
Purpose: To examine the distribution of intraocular pressure (IOP) and its related systemic and ocular biometric factors in a population-based study in a southwestern island of Japan.
Design: Cross-sectional, population-based study.
Methods: All residents of Kumejima Island, Japan, located in southwestern Japan (eastern longitude, 126 degrees 48 minutes and northern latitude 26 degrees 20 minutes), 40 years of age and older were asked to undergo a comprehensive questionnaire and ocular examination, including measurement of IOP with Goldmann applanation tonometry.
Purpose: To examine the distribution of corneal endothelial cell density (ECD) and relating factors in ophthalmologically normal Japanese in a population-based setting.
Design: Cross-sectional, population-based study.
Methods: All residents of Kumejima Island, Japan, located in southwestern Japan (eastern longitude 126 degrees 48' and northern latitude 26 degrees 20'), aged 40 years and older, were asked to undergo a comprehensive questionnaire and ocular examination, including noncontact specular microscopy of corneal endothelial cells.
Purpose: To determine the prevalence and risk factors for pterygium in a Japanese population aged 40 years or older on Kumejima Island, Japan.
Design: Cross-sectional, population-based study.
Methods: All residents of Kumejima Island, Japan, located in Southwestern Japan (Eastern longitude 126 degrees, 48 feet and Northern latitude 26 degrees, 20 feet), aged 40 years and older were asked to undergo a comprehensive questionnaire and ocular examination.
Purpose: To demonstrate the efficacy and safety of deep lamellar keratoplasty(DLKP) in the treatment of corneal opacity in severe ocular surface disease.
Methods: A total of 12 eyes of 11 patients were analyzed in this retrospective case series. The original diseases were Stevens Johnson syndrome (SJS : 3 eyes), ocular ciccatricial pemphigoid(OCP : 2 eyes), thermal burns (2 eyes), limbal deficiency due to unknown cause (2 eyes), and corneal scarring due to trachoma (3 eyes).
