Clinical outcome of Tenon’s patch graft and bandage contact lens in cases of corneal perforation

Abstract

Background: Corneal perforation is a leading cause of ocular morbidity around the world. It may occur due to trauma to the eye, keratitis, and many other conditions. Any corneal perforation should be treated immediately and promptly to avoid complications and subsequently corneal blindness.Objective: To describe effectiveness of using autologous Tenon’s tissue along with bandage contact lens to manage corneal perforations less than 3 mm in size.Methods: Tenon’s patch graft was done in five cases of corneal perforation. Informed consent was obtained from the subjects after explanation of the nature and possible consequences of the study and this study was approved by ethical committee.Results: Of the five patients the first patient she showed good integration of the Tenon’s Patch Graft (TPG). She had a vision of Perception of Light+ and accurate projection of rays after a period of 5 months post procedure. The wound healed with a glaucomatous scar. Case two had a vision of counting fingers close to face after five months. Case three showed good integration of the TPG. He had a vision of 6/60 accurate after a period of three months post procedure. In case four anterior chamber was shallow, post patch integrity was not maintained. Patient was later considered for penetrating keratoplasty. Case five showed integration of TPG after one week postop with vision counting fingers at 6 meters.Conclusion: We conclude that Tenon's Patch Graft with bandage contact lens is an effective technique in the treatment of corneal perforations. Using this, the integrity of the eyeball can be maintained without any danger of graft rejection since the tissue is autologous. This technique can be used effectively in places where resources are scant.
