Main description:

The 11 th Congress of SIDUO took place in the beautiful setting of Capri in springtime and was held in the impressive and stimulating atmosphere of the 'Certosa di S. Giacomo'. The organisation was sponsored by the SIEO, the 'Societa Italiana di Eco- Oftalmologia'. The Honorary President was Professor Antonio Rossi, Head of the University Department of Ophthalmology in Ferrara and one of the pioneers of Italy in this field. The organizing committee further consisted of: President: Prof. P. E. Gallenga, University Department of Ophthalmology, Chieti Vice President: Dr. G. Cennamo, University Department of Ophthalmology, Napels Scientific Secretary: Dr. J. M. Thijssen, University Department of Ophthal- mology, Nijmegen Treasurer: Dr. A. Reibaldi, University Department of Ophthalmology, Bari The organizing Committee was supported by an International Scientific Pro- gramme Committee: Regional Representatives: SIDUO Officers: G.
