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 purpose of this symposium on light-coagulation is not to show the superi ority of the argon-laser-coagulation or, on the contrary, of the classical photo coagulation, but rather to see, if possible, which are the respective indications and contraindications for xenon-are-coagulation as well as for argon-laser coagulation.

The European Glaucoma Society was founded in the spring of 1978 at the initiative of Drs Fran~ois, Leydhecker and Greve. The European Glaucoma Society serves to stimulate glaucoma research and diffuse specific knowledge to general ophthalmologists.

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.

The proceedings of this symposium on Medical Therapy in Glaucoma are divided in four major parts. The new and exciting field of drug delivery systems will be dealt with in this part and part II. Part II on cholinergic action offers next to the well-known drugs infor mation about Ocusert.

Each year the improvements in communication and transportation, the growing awarness that the resources of this earth are finite, the realization that the population explosion in any part of the world is a concern of all, and the increased economic interdependence of all countries, have increased importance of internationalism as opposed to nationalism. One of the first segments of our society to ignore political and geographic boundaries was that of medicine, particularly in the field of communicable diseases. Valient efforts have been made by some individuals at great personal sacrifice and by individual societies or organizations to prevent and cure blindness and to rehabilitate those who have lost their sight. Only recently, however, have such efforts been consolidated into a major international force. In 1969 the 22nd World Health Assembly of WHO adapted a resolution requesting the Director-General to undertake a study on the information which is at pre­ sent available on the extent and/or causes of preventable and curable blind­ ness. In 1972 a working group was convened by the World Health Organiza­ tion in Geneva to outline an attack on the prevention of blindness. At the Paris meeting of the International Congress of Ophthalmology in July of 1974, Mr. JOHN WILSON, who for many years had been one of the leaders in the prevention and cure of blindness on an international basis through his organization of the Royal Commonwealth Society for the Blind, was elected President of the International Association for Prevention of Blindness.

Two groups of volunteers having no eye disease were examined electro-oculo­ graphically twice at ten minute intervals. One group smoked in the break, one didn't. In the non-smoking group there are a number of significant correlations between the tested parameters in the dark-period and in the light-period, which could not be found to the same degree in the smoking group. The fact that there were differences between the two groups-even though not interpretable systematicaIly-suggests, that smoking influences physiological processes in the EOG. In the second period of the test, a parallelism in the course of EOG and EEG was observed, the EEG-changes, however, are interpreted more psychologically than pharmacologicaIly.
