Abstract:
:The cell culture method was used to quantitatively evaluate the cytotoxicity to porcine corneal endothelial cells by drugs in the usual concentrations of intracameral injections (ICI). Time-dependent cytotoxicity of drugs was evaluated quantitatively; dye exclusion assay by trypan blue was used as a viability assay; and cytotoxicity to corneal endothelium was tested using amphotericin-B, amikacin, colistin, sulbenicillin, and cephradine in their original, 10-fold, and 100-fold ICI concentrations. Original and 10-fold ICI concentrations of betamethasone also were used. In original and 10-fold ICI concentrations, only amphotericin-B had significant cytotoxicity. In 100-fold ICI concentrations, amphotericin-B, colistin, and sulbenicillin had significant cytotoxicity. Betamethasone had neither a cytotoxic nor a proliferative effect in its original and 10-fold ICI concentrations. A 0.1-fold ICI concentration of amphotericin-B also showed 42.75% cytotoxicity to corneal endothelium by monolayer cultured cells and the time-dependent cytotoxicity of drugs as a quantitative method is efficient and objective.
