Drawing in 15 840 patients treated at the First Eye Clinic of the University of Vienna between 1966 and 1980, 273 cases of hemorrhagic secondary glaucoma were selected for a special study. After a historical review of the semantic change which the expression "hemorrhagic glaucoma" has undergone etiological factors are investigated. Hemorrhagic glaucoma occurred after occlusion of the central retinal vein in 52.7% of the cases, as a result of diabetes mellitus in 37.3%, after iridocyclitis chronica recidivans in 3.7%, following retinal detachment in 1.8%, as a result of intraocular tumors in 1.8%, after occlusion of the central artery in 1.1% and after an apoplectic shock in 0.4%.

An examination of 43 eyes which had undergone goniotrepanation in accordance with Fronimopoulos showed that blood coagulation plays a major part in the postoperative cicatrization of the filtering scar. Patients with short postoperative haemorrhages or with high rates of thrombocytes tend to suffer postoperative hypertension of the eye, whereas patients with haemorrhages of over 1 minute or with low rates of thrombocytes often have the clinical symptoms of postoperative hypotony.

Corneal sensitivity was measured in 91 eyes suffering from chronic open-angle glaucoma using the electronic-optical hand esthesiometer after Draeger. It was found that the threshold value in eyes with glaucomatous cupping or atrophy of the optic nerve was significantly increased, in contrast to eyes with normal optic disks, but that there was no direct relationship between IOP at the time of measurement and the duration of the open-angle glaucoma. The reduced sensitivity was due to damage of the long ciliary nerves between the choroid and sclera. The authors' findings thus support the view that glaucomatous atrophy of the optic nerve is caused by primary pressure atrophy of the retina.

Die 30. Tagung der ECLSO, der europaischen Vereinigung der kontaktlinsenanpassenden Augenarzte fand diesmal vom 27. bis 30. September 2000 in der Sudturkei, in Antalya statt. Die lokalen Organisatoren batten sich sehr bemuht, um einen klaglos funktionierenden Kongress auf die Beine zu stellen. Die Tagung war in dem luxuriosen Sheraton Voyager Hotel direkt am Ufer des turkisfarbenen Meeres lokalisiert. Prachtig sonniges Spatsommerwetter machte es einem Abb. 1.
