Prevalence and risk factors of pterygium in a southwestern island of Japan: the Kumejima Study.

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.

A comparison of fluoroquinolone penetration into human conjunctival tissue.

Introduction: Ocular penetration of newer fluoroquinolones (FQs) has not been fully investigated in humans, especially in regard to conjunctival tissue penetration. The aim of our study was to evaluate the conjunctival permeability of 3 FQs, which do not contain benzalkonium chloride, using excised pterygium tissue.

Methods: Patients undergoing pterygium surgery received a single application of one of the following: 0.

Corneal opacity and cataract: triple procedure versus secondary approach.

Purpose: To determine the efficacy of planned secondary cataract surgery after keratoplasty.

Methods: Twenty patients (22 eyes) with simultaneous corneal pathology and cataract were enrolled in a prospective, interventional, case-matched, nonrandomized comparative trial. Penetrating keratoplasty (PKP) and extracapsular cataract extraction (ECCE) with IOL insertion (triple procedure) were performed in 11 eyes, and planned phacoemulsification (PEA) with IOL insertion after PKP was performed in 11 case-matched eyes.
