Proceedings of the Seventh Symposium of the International Research Group on Colour Vision Deficiencies Held at Centre Medical Universitaire, Geneva, Switzerland, 23-25 June, 1983

Proceedings of the Sixth Symposium of the International Research Group on Colour Vision Deficiencies

Proceedings of the symposium held in Annapolis, Md. July 1987. Major topics include: polymorphisms of normal color vision and inherited color defects; theoretical studies of color vision; cortical mechanisms of normal and abnormal color vision; acquired color vision deficiencies in retinal disorders

Colour Vision Deficiences VIII brings together information on the latest trends in the following areas of research: -Visual effects of intense lights; -Effects of intoxications on colour vision; -Ageing and vision; -Methods of examination; -Congenital defects; -Acquired defects; -Practical aspects; -Physiological bases.
This volume is a natural follow-up on Volumes VI and VII published in 1981 and 1983 respectively by Dr. W. Junk Publishers.

The 4th International Visual Field Symposium of the International Perimetric Society, was held on the 13-16 April 1980 in Bristol, England, at the occasion of the 6th Congress of the European Society of Ophthalmology. The main themes of the symposium were comparison of classical perimetry with visual evoked response, comparison of classical perimetry with special psychophysi cal methods, and optic nerve pathology. Understandably many papers dealt with computer assisted perimetry. This rapidly developing subgroup of peri metry may radically change the future of our method of examination. New instruments were introduced, new and exciting software was proposed and the results of comparative investigations reported. There have been many confusing statements in the literature on the relative value of perimetry and the registration of visual evoked responses. Several reports attempted to bring some clarity in this issue. There is reason for further comparative research. A number of papers dealt with special psychophysical methods, i.e. methods not using the simply monocular differential threshold. The old critical fusion frequency received new attention. Fundusperimetry was used for testing spatial summation. Acuity perimetry, binocular perimetry etc. showed that there exist many possibilities for examining visual function. At present it is not clear to us what exactly the place of these methods is in our diagnostic armament. However it is quite clear that some of them are promising and may lead to a further differentiation of perimetric methods."
