The effect of intraocular dilating solution on cat endothelium

Maintenance of pupillary dilatation can be a difficult problem. We found a dilute intraocular solution of atropine and epinephrine to be both effective and safe in inducing pupillary dilatation. No significant corneal endothelial toxicity could be demonstrated in the cat eye comparing preinjection and postinjection endothelial cell density.
