Abstract

Anterior keratectomy (AKE) was done on rabbits, and the appearance of immunohistochemically demonstrable tenascin (TN) or cellular fibronectin (cFN) was studied at different times (5 min to 14 months) after the operation. The substance TN was first observed 12 hr after wounding in the posterior stroma; cFN appeared with the same localization 12 hr later. During postoperative week 1, both TN and cFN immunoreactions shifted to more anterior parts of the cornea, and 9 days after wounding, they were localized in the most anterior part of the stroma only. Thereafter the reactions gradually decreased in intensity but still were visible 3 months after AKE. No reaction for TN or cFN was present 14 months postoperatively.
