Ultrasonography in Ophthalmology XV: Proceedings of the 15th SIDUO Congress, Cortina, Italy 1994 (Documenta Ophthalmologica Proceedings Series, 61)

When in the early 60s echography was introduced into the field of ophthalmol­ ogy, very few ophthalmologists realized the enormous potential of this procedure, the fundamental impact it would have on our branch of medicine or the innovations it would spawn. From its hesitant beginnings, echography has led to revolution in the field of ophthalmology and to our way of examining, treating and monitoring patients affected by eye disorders. This technique has brought untold benefits to patients worldwide. A crucial element in fostering the advance of the application of ultrasound in ophthalmology has been and is the biannual conference of the Societas Internationalis pro Diagnostica Ultrasonica in Ophthalmologia (SIDUO), and incidentally, the Latin name reflects the wish of the founding members that SIDUO be truly international, and even though the instruments and apparatus used in the discipline are highly innovative, the underlying philosophy is one that traces back to Hippocrates, i.e., the healing of man and the improvement of man's quality of life.
