Produktbeschreibung
Excerpt from The American Journal of Ophthalmology, Vol. 18: January, 1901 The retina was totally detached and ran forward from the optic nerve entrance in the shape of a thick chord towards the evelitic membrane into which it merged. Bone formation was seen to cover the whole of the inner surface of the choroid. On microscopic examination the circular synechia of the pupillary margin of the iris is especially conspicuous. The tissue of the iris containing the sphincter muscle is slightly folded backwards upon the anterior lens-capsule, where the synechia is found. Into the pupillary space an anterior polar cataract of the usual appearance is projecting. Iris and ciliary body are largely infiltrated with round cells, their blood-vessels hyperæmic. In the lamellar tissue of the polar cataract numerous deposits of amorphous lime are found. The remainder of the lens shows cataractous degeneration throughout. The nucleus is so large that there is hardly any cortical substance. At the base of the anterior polar cataract there are large spots in which the lens-epithelium has proliferated enormously. The whole of the posterior lens-capsule is lined with an almost unbroken layer of epithelial cells. The cyclitic membrane consists of a dense fibrous tissue containing many nests of pigmented cells and a great deal of free pigment. In numerous places there are small round-cell accumulations which have taken up the hæmatoxyline stain with much more avidity than the surrounding tissue, and are therefore probably of very recent date. Their arrangement gives the impression of a septic inflammation, yet I have not succeeded in finding any microbes in, or in the neighborhood of, these round-cell aggregations. There are also numerous deposits of amorphous lime and some patches of bone-tissue in the cyelitic membrane. Posteriorly, the retina is attached to this membrane. It is undergoing atrophy and its histological conditions are in no way remarkable, except for round-cell aggregations and deposits of amorphous lime, similar to those found in the cyclitic membrane. The most interesting part of this eye is the bone formation, which is very extensive. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
