The 14th Congress of SIDUO, held in Tokyo from October 26 to October 30, 1992, was the first congress meeting to be held in Asia in the 30-year history of SIDUO. The congress was organized by the Department of Oph thalmology, St. Marianna University School of Medicine, with the support of the Japanese Ophthalmological Society, the Japan Society of Ultrasonics in Medicine and the Japan Society of Ophthalmologists. The organizing committee consisted of the following members. Congress President: Sadanao Tane, M. D. (Professor and Chairman, St. Marianna University School of Medicine) Vice-presidents: Atsushi Sawada, M. D. (Professor and Chairman, Miyazaki Medical College) Masayasu Ito, Ph. D. (Tokyo University of Agriculture and Technology) Secretary General: Yasuo Sugata, M. D. (Tokyo Metropolitan Komagome Hospital) Finance Committee: Koji Ohashi, M. D. (Assistant Professor, St. Marianna University School of Medicine) Akira Komatsu, M. D. (Assistant Professor, St. Marianna University School of Medicine) Toshio Kaneko, M. D. (Assistant Professor, St. Marianna University School of Medicine) Publicity and Exhibition Committee: Hideyuki Hayashi, M. D. (Assistant Professor, School of Medicine, Fukuoka University) Akihiro Kaneko, M. D. (National Cancer Center) The Honorary Presidents were Yukio Yamamoto, M. D. (Tokyo Tama Geriatrics Hospital) and Yasuo Uemura, M. D. (Professor Emeritus, Keio University) . The opening ceremony began with the Francois Memorial Lecture given by Professor Peter Till (Standardized Echography: Quantitative Analysis of XlI Tissue Backscatter - A Major Source of Information for Tissue Diagnoses).
