This volume contains the papers presented at the International Symposium on Fluorescein Angiography held in Ghent, from 28 march to 1 april 1976, under the presidency of Prof. J. Fran90is. The book has been divided in several chapters corresponding to the sessions of the meeting. The same order has been followed as for the pre­ sentation of the papers. The discussions, however, immediately follow the papers concerned. During the meeting complications of fluorescein angio­ graphy have been discussed; this part will be presented as a separate chapter at the end of the volume. I wish to express my gratitude to all who contributed to this volume and to all the participants of ISF A-Ghent. I acknowledge also the cooperation of the publishers Dr. W. Junk, B.V. J.J. De Laey, M.D. XI EDITORIAL We must be respectfully grateful to Her Majesty the Queen, who very kindly extended her high patronage to the International Symposium on Fluorescein Angiography.
