WebCytotoxicity assays measure loss of some cellular or intercellular structure and/or functions, including lethal cytotoxicity. They thus give an indication of the potential to cause cell and tissue injury and as such have been used by some investigators to predict tissue injury, including eye injury. WebQualitative evaluation involves observing the cells under a microscope and assigning a cytotoxic grade (0-4). The grade is based on an estimated percent lysis (death) and on the morphology (appearance) of the cells. Test materials pass the assay if the cytotoxic score is ≤ 2 (≤ 50% lysis).
