摘要:
Supplementation of tissue culture medium with chon-droitin sulfate has been shown to enhance donor corneal preservation. We assessed the efficacy of one of these chondroitin-supplemented media (K-Sol) in comparison with McCarey-Kaufman (MK) medium in maintaining corneal cellular morphology. Thirty-six human corneas, obtained within 8.6 h after death, were placed into K-Sol medium for up to 20 days preservation, and five paired control corneas were placed into MK medium for up to 6 days preservation. Specular photomicrographs were obtained every second to third day for a predetermined stor-age interval, then studied morphologically in a masked protocol by light microscopy, transmission electron mi-croscopy, and scanning electron microscopy. Endothelial cell loss by specular microscopy averaged 5.8% after 1 week (6 to 8 days) and 7.4% after 13 days in K-Sol me-dium. Epithelial changes were erratic throughout the 20 day K-Sol preservation period. However, substantial keratocyte changes occurred after 10 days, and endothe-lial morphology uniformly deteriorated after 17 days. The morphologic data suggest that human corneas may be able to be preserved in K-Sol medium at 4A°C for up to 10 days but should be cautiously used thereafter.

摘要:
A case of central crystalline dystrophy of Schnyder is presented in which ultrastructural studies were performed on the corneal specimen after penetrating keratoplasty. Electron microscopic changes were documented not only in the anterior but in the posterior stroma and in the corneal endothelium. In the posterior stroma and at the interface between the stroma and Descemeta's mem-brane, numerous ovoid, electron-lucent spaces were present that most likely represented foci of lipid deposi-tion. In addition, rare, focal areas of endothelial cell degeneration were observed that produced minute discontinuities in the endothelial cell covering of Descemeta's membrane. Changes in the posterior layers of the cornea in Schnydera';s crystalline dystrophy may contribute to the comparatively poorer surgical results obtained with lamellar rather than full-thickness grafts in these cases.
