We report on the clinical symptoms and the course of a case that showed the typical findings of a meningioma of the optic nerve sheath, characterized by visual disturbances, progressive visual field defect, proptosis, secondary atrophy of the optic disc, and shunt vessels between retinal and choroidal circulation. The shunt vessel which was demonstrated in this case by fluorescein angiography is identified with the optociliary vein reported in the literature. ⋯ The tumor was removed through a frontotemporal craniotomy, preserving the optic nerve. The histopathological diagnosis was meningothelial meningioma.

In 13,440 bacteriological investigations the effectivity of different methods for desinfection of Goldmann tonometer prisms (merfen, pantasept, sekusept steril, UV sterilizer Sklar) is tested. Sekusept steril and UV sterilizer show the quickest and most sufficient results. They cause no damage to corneal epithelium or to plastic objects. We can recommend them for desinfection of applanation tonometer prims, Goldmann's gonioscopy and fundus contact lenses as routine methods.
