[Survey of severe contact lens-associated XXXX in Japan].

@entity1 @entity5517 @entity1036
PURPOSE: To understand the current state of severe contact lens (CL)-associated @entity1036 in Japan. METHOD: The survey was conducted by the Japan Contact Lens Society and the Japanese Association for @entity5517 in 224 facilities from April 2007 to March 2009. @entity1 who were diagnosed with CL-associated @entity1036 and hospitalized for treatment were enrolled. Clinical characteristics of the @entity1036 , microbiologic findings and the status of CL hygiene were studied. RESULTS: A total of 350 @entity1 were investigated, with an average age of 28.0 (9-90) years. Acanthamoeba was identified in 85 (24.3%) corneal specimens and Pseudomonus aeruginosa in 70 (20.0%) cases. One hundred ninety six (56.0%) @entity1 were frequent replacement soft CL users. Extended wearing of daily-use CLs was found in 77 (22.0%) @entity1 . Only 67 cases maintained good CL hygiene by daily rubbing-washing and the poor CL care situation was reviewed. CONCLUSION: The most frequently detected pathogenic microorganism was Acanthamoeba, followed by Pseudomonus aeruginosa. Our survey showed the importance of keeping good CL hygiene by proper lens care, and improvement of CL-related social regulations is urgently needed.
