[Light and electron microscopy in one case of herpes zoster keratitis (author's transl)]. 1978

M Berard, and J M Merlihot, and N Mouillac-Gambarelli, and R Choux, and L Andrac

One case of herpes zoster keratitis studied after corneal graft is described. Light and electron microscopy investigations show severe pathological changes under the coneal epithelium: Bowman's layer disruption, superficial stromal alterations, sub-epithelial phagocyte proliferation with lipid and mucopolysaccharid vacuolar deposits, abnormal vascularization of the posterior stroma. The authors stress on this interesting ultrastructural study because of very rare cases of the same disease reported in the literature.

UI MeSH Term Description Entries
D007634 Keratitis Inflammation of the cornea. Keratitides
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy

D003315 Cornea The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.

D006025 Glycosaminoglycans Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE).

D006563 Herpes Zoster Ophthalmicus Virus infection of the Gasserian ganglion and its nerve branches characterized by pain and vesicular eruptions with much swelling. Ocular involvement is usually heralded by a vesicle on the tip of the nose. This area is innervated by the nasociliary nerve. Herpes Zoster, Ocular,Ocular Herpes Zoster
