Effect of vidarabine and related compounds on corneal endothelium

The endothelial surface of rabbit corneas was perfused with vidarabine monophosphate (with and without adenosine deaminase inhibitor), vidarabine (with and without adenosine deaminase inhibitor), and ara-Hx. In concentrations 10 times to 1,500 times higher than those that have been obtained in the aqueous humor following topical, subconjunctival, or systemic administration, none of the compounds had any effect on corneal endothelial cell function or ultrastructure for the duration of the experimental model.
