Membrana amniótica bovina, preservada em glicerina, na reparação da córnea após ressecção de tumor dermoide em um cão – relato de caso

Abstract

A Shih Tzu with pigmented tissue containing hair in the right cornea was presented to a teaching hospital. A corneal dermoid tumor was diagnosed after ophthalmic examination. The patient underwent superficial keratectomy and lamellar keratoplasty using bovine amniotic membrane preserved in 99% glycerin. At fifteen days post-surgery, the presence of granulation tissue, vascularization, corneal edema and incorporation of the membrane to the cornea were observed. After thirty-nine days, the cornea presented moderate opacity, and seventy-four days after the surgery it had decreased considerably and was satisfactorily transparent, indicating a positive result. Taken together, the results presented herewith lead us to conclude that the bovine amniotic membrane was effective in corneal reconstruction after superficial keratectomy to remove the corneal dermoid tumor, since its use allowed the repair of the cornea.
