This book was released on 2021-06-17 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Vitrigel-Eye Irritancy Test (EIT) method is an in vitro test method that allows the identification of test chemicals not requiring classification and labelling for eye irritation or serious eye damage. This test measures the eye irritation potential of a test chemical based on its ability to induce damage to the barrier function of the human corneal epithelium (hCE) models used in the Vitrigel-EIT method. It is known that chemicals that are irritating to the eye first destroy tear film and epithelial barrier function of the eye, subsequently induce epithelial cell death, and finally produce stromal degeneration and endothelial cell death, resulting in corneal opacity. Therefore, the change of the epithelial barrier function is a relevant endpoint for detecting eye irritation. In the Vitrigel Eye Irritancy test method , time-dependent changes in the Transepithelial Electrical Resistance (TEER) values are indicative of damage to the barrier function of the corneal epithelium following exposure to a test chemical; this situation is similar to the observed damage of the rabbit cornea following exposure to a test chemical, which is an important mode of action leading to damage of the corneal epithelium and eye irritation. The Vitrigel-Eye Irritancy Test (EIT) method can be used within the limited applicability domain of test chemicals having pH > 5.0 (based on 2.5% weight/volume (w/v) preparation).

This book was released on 2015 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Test Guideline describes an in vitro procedure allowing the identification of chemicals (substances and mixtures) not requiring classification and labelling for eye irritation or serious eye damage in accordance with UN GHS. It makes use of reconstructed human cornea-like epithelium (RhCE) which closely mimics the histological, morphological, biochemical and physiological properties of the human corneal epithelium. The test evaluates the ability of a test chemical to induce cytotoxicity in a RhCE tissue construct, as measured by the MTT assay. Coloured chemicals can also be tested by used of an HPLC procedure. RhCE tissue viability following exposure to a test chemical is measured by enzymatic conversion of the vital dye MTT by the viable cells of the tissue into a blue MTT formazan salt that is quantitatively measured after extraction from tissues. The viability of the RhCE tissue is determined in comparison to tissues treated with the negative control substance (% viability), and is then used to predict the eye hazard potential of the test chemical. Chemicals not requiring classification and labelling according to UN GHS are identified as those that do not decrease tissue viability below a defined threshold (id est, tissue viability > 60%, for UN GHS No Category).
