Perimetry Update 1998/99 contains a selection of papers and posters presented at the XIIIth Visual Field Symposium of the International Perimetric Society. This peer-reviewed volume provides a convenient source for most of the perimetric research presently being undertaken world-wide.

The XIIIth. Symposium took place between September 6th and 9th, 1998, at the Grand Hotel, Gardone Riviera, Italy, hosted by Professor Enrico Gandolfo of the University of Brescia, and was attended by over 250 delegates. The setting for the Symposium, on the shore of the picturesque Lake Garda, provided an idyllic location for the scientific sessions of the Symposium and for the social functions of the Society.

Once again, the presentations within the scientific sessions were of a high standard. A total of 122 abstracts had been submitted for review. Of these, 52 were selected by the Program Committee for presentation as oral papers, and 57 as poster presentations. The posters were displayed throughout the Symposium, allowing delegates and authors plenty of opportunity for discussion. As was the case at the last Symposium, public discussion of each poster presentation was included within the scientific sessions. The topics presented at the XIIIth Symposium embraced all aspects of perimetric science. A total of ten sessions were held and covered: fundamentals of perimetry, visual psychophysics, new perimetric techniques, new algorithms for estimating threshold, perimetric variability, color perimetry, optic nerve head imaging, and visual field investigation in glaucoma and in retinal and neurological disorders. The new perimetric techniques included frequency doubling technology, flicker perimetry and pupil perimetry. The new algorithms included the Swedish Interactive Threshold Algorithm (SITA) and Tendency Orientated Perimetry (TOP). The session on perimetric variability addressed some of the issues contributing to short-term fluctuation, and also contained papers on the use of univariate linear regression of point-wise sensitivity against time to follow-up for the identification of progressive visual field loss. The session on color perimetry was almost exclusively concerned with Short Wavelength Automated Perimetry (SWAP), particularly in glaucoma and high risk ocular hypertension. However, one group described a seemingly promising additional use for SWAP; namely, in the detection of diabetic macular edema. The presentations within the imaging session described the latest morphometric and topographic parameters derived by optic nerve head and nerve fiber layer analysis, and compared these structural measures with those of the functional assessment. In the current financial climate, no scientific symposium can take place without the endorsement of industry. The technical exhibition was supported by ten companies drawn from both the pharmaceutical industry and the instrument manufacturers. The Society is, in particular, indebted to Alcon International and Humphrey Instruments and Welch-Allyn combined, for the generous financial contribution received. These contributions reduced the cost of delegate registration. The organization of the Symposium was excellent. In this respect, the Society owes its gratitude to the Program Committee, the Local Organizing Committee and, in particular, to the local host, Professor Enrico Gandolfo. The publication of this volume was also dependent upon the cooperation and goodwill of the authors and of the peer reviewers from the Board of the Society. I would like to express my personal gratitude to the Secretary of the Society, Dr. Michael Wall, for his enthusiasm and commitment to the Society, and for his unstinting efforts in the organization of the Symposium and of this volume. We all look forward to the next Symposium, IPS 2000, which will be held at the World Trade Centre in Halifax, Nova Scotia, Canada, between September 6th and 9th, 2000, under the direction of the local host, Dr. Balwantray Chauhan
