The Seventh International Meeting on Scanning Laser Ophthalmoscopy, Tomography and Microscopy was held between November 30 and December 3, 1999 at the City of San Carlos de Bariloche, in the Argentine Patagonia. This scientific meeting gathered professionals from allover the world whose current research interests are confocal tomography, scanning laser Doppler flowmetry, digital angiography with indocyanine green and fluorescein, po larimetry, optical coherent tomography and many other different techniques. Moreover, according to the proposal made on the occasion of the Meeting, the International Society of Laser Scanning (INSOLAS) was formally created by voting. This is the first international society which will focus exclusively on the application of laser diagnostic technologies in ophthalmology. As originally conceived for an optimal coverage of the whole range of interests, the event was divided into a technical area, a research area, and mainly, a clinical application area for each technology. It is our wish that this book, compiling the presentations made at the Meeting and which will constitute the first publication of the INSOLAS, will be spread and distributed among all practical and clinical ophthalmologists around the world. The Executive Committee of the 7th IMSLO is particularly grateful to the following sponsors, whose financial support has made this event possible: Alcon-Humphrey Instruments, Heidelberg Engineering, Allergan, Novartis Ophthalmics, Pharmacia & Upjohn and Pfortner Cornealent. Our thanks also to the following entities: Fundaci6n Argentina Oftalmol6gica Juan Sampaolesi, Fundaci6n Bridas Argentina and Fundaci6n Amalia Lacroze de Fortabat."
