Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The proceedings of this symposium on Medical Therapy in Glaucoma are divided in four major parts. The pharmacological introduction gives the reader a short description of factors that are involved between administration of the drug and its action at the desired position in the eye. The new and exciting field of drug delivery systems will be dealt with in this part and part II. Originally we had asked Ken Richardson to give part of the lectures on Membrane technology and basic aspects of cholinergic action. Unfortu nately at the last moment he could not come. Our thanks go to Gavin Paterson and Klaus Heilmann who were willing to take over a part of his job. Part II on cholinergic action offers next to the well-known drugs infor mation about Ocusert. Part III covers the new developments in the adrenergic field, including guanethidine and atenolol. The clinical aspects of medical therapy in glaucoma are covered by Part IV. Many subjects could not be handled. We left out the systemic treatment of glaucoma (diamox, mannitol etc.). We left out all special cases and prob lem cases. Some questions could be answered during the round table discus sion, most remained unanswered. It is clear that there is enough subject-mat ter and interest for another symposium on therapy of glaucoma.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - does not vary more than 1 % over the whole surface. Stimulus: The luminance of the stimuli can be regulated by means of neutral density filters. These filters are neither entirely neutral nor completely uniform, but these variations are not significant for perimetry. The maximum luminance of the stimuli is standardized at 1000 asb (316 2 cd.m-). The standard GP for kinetic perimetry has 3 neutral density filters which reduce the luminance by 0.5, 1.0 and 1.5 log units respectively. The modification of the GP for static perimetry is supplied with an additional series of four neutral density filters, which allow luminance steps of 0.1, 0.2, 0.3 and 0.4 log units. The resulting luminance values, expressed in apostilb, are given in Table I.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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 programmes. All these changes could be made without modification of actual instrument hardware. REFERENCES 1. Dannheim, F. and Drance, S.M. Psycho visual disturbances in glaucoma.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The European Glaucoma Society was founded in the spring of 1978 at the initiative of Drs Fran~ois, Leydhecker and Greve. Representatives of most European countries met in Ghent and agreed to create a society that would promote the contacts and exchange of knowledge between European glauco matologists. The European Glaucoma Society serves to stimulate glaucoma research and diffuse specific knowledge to general ophthalmologists. The European Glaucoma Society would like to cooperate closely with similar glaucoma organizations in other continents. The first symposium of the EGS was held in April 1980 in Brighton, England. No proceedings were published. The second symposium took place in May 1984 in Hyvinkiiii, Finland. A great number of participants enjoyed a well organized scientific programme of attractive quality. The local organization was in the able hands of Raitta and her colleagues, Raivio and Lehto. The scientific programme was coordinated in Amsterdam where a great amount of work was done by Stella Ompi, secretary to the general secretary. The contents of the meeting have been summarized in this book. This second symposium of the EGS, which took place in an atmosphere of great enthusiasm and friendship, has shown great promise for the future of the European glaucoma.
