Proceedings of the Ninth symposium of the International Research Group on Colour Vision Deficiencies, held at St. John's College, Annapolis, MD, July 1-3, 1987.

The Seventh International Visual Field Symposium organized by the Interna tional Perimetric Society was held in Amsterdam, The Netherlands, September 6-10,1986. In many respects it was an exciting and fruitful meeting. The number of participants was greater than ever. The number of papers was too great to accommodate all of them. The quality of the papers reflects the continuously rising interest in perimetry in general and in automated perimetry in particular. Last but not least the social programme was organized in the, by now, almost classical friendly, enjoyable and humouristic style of...

Over the past few years there have been considerable advances in our understanding of the normal development of vision and in our ability to detect and meaSl1re visual impairment in early childhood. It was appropriate, therefore, that a workshop, sponsored by the European Communities, should be held on the 'Detection and Measurement of Visual Impairment in Pre-verbal Children.' This workshop, which was held at the Institute of Ophthalmology, London, between 1 and 3 April 1985, brought together visual physiologists and ophthalmologists who exchanged and discussed ideas of mutual interest....

The HF A is a computerized perimeter with a very comprehensive set of test point patterns, strategies and custom tests. The instrument employs several solutions which have proved useful in earlier computerized perimeters and several new concepts. The construction with stimulus generation through a projection system, input through a CRT, programmes stored in PROMs and a double disc drive for storage of test results makes it simple to adapt the instrument to future needs, whether these are new test algorithms or point patterns, different input or display screens or new statistical analysis...
