Scanning electron microscopic evaluation of the effects of intracameral injection of cyanoacrylate in the rabbit.

We examined, using scanning electron microscopy, the effects of the injection of an isobutyl cyanoacrylate into the rabbit anterior chamber. Injection of the adhesive produced a rapidly polymerized mass that remained in the anterior chamber throughout the course of the study. Additionally, an active inflammatory response was noted in the anterior chamber, characterized by a progressively enlarging "cocoon" of fibrin and inflammatory cells surrounding the polymerized adhesive, as well as inflammatory cells in the trabecular meshwork. Following cyanoacrylate injection, the corneal endothelial cells were noted to be swollen for the first 14 days of the study.
