Twenty-two patients with a recently developed C.R.V.O. (central retinal vein occlusion) (symptoms: less than four weeks) are discussed. A delay in A.R.C.T. (arm to retina circulation time) in the affected eye was found in two patients with an ischaemic type of C.R.V.O. and in 3 patients with a non-ischaemic type of C.R.V.O. No side difference could be(More)

The project on crystallographic modelling aims at extending the application of interactive graphics to inorganic structures. Starting from the available expertise in organic and protein modelling, the symmetry of the crystal structure is used not only to draw fixed models of many unit cells of the structure, which as an entity can be interactively(More)
