Essential ions for maintenance of the corneal epithelial surface.

摘要: It is generally believed that tears are required to furnish only oxygen the corneal epithelium. However, as a very complicated solution, it likely other factors essential cells of surface. The amount light scattered from epithelial surface excised rabbit cornea was examined with in vitro specular microscope while epithelium bathed different solutions. shown maintained best buffered solution containing potassium, calcium, magnesium, phosphate and bicarbonate, addition sodium chloride. named Basic Tear Solution (BTS). effect not due osmolarity. Potassium particularly important, corneas chloride potassium were better than only. appearance these bathing In more sloughed. Least BTS, cell-sloughing at minimum. Thus, rate which sloughed quality dependent on solution.
