RESUMO
PURPOSE: To report cases of corneal perforation among corneas treated with cyanoacrylate tissue adhesive. METHODS: We performed cyanoacrylate tissue adhesive application on 1 case of corneal perforation due to fungal keratitis, one case of corneal perforation due to neurotrophic keratitis, one case of corneal fistula due to foreign body and one case of corneal perforation due to corneal stromal dystrophy. After cyanoacrylate tissue adhesive removal, amniotic membrane transplantation was conducted in two cases, and keratoplaty was performed in another two cases. RESULTS: Postoperative follow-up period was 12 months on average. In all four cases, ocular integrity was successfully restored. There was no sign of recurrence, infection or inflammation. CONCLUSIONS: Cyanoacrylate tissue adhesive monotherpy can restore ocular integrity successfully in various type of corneal perforation and After cyanoacrylate tissue adhesive removal, amniotic membrane transplantation and keratoplaty can be performed additionally.

Objective To evaluate the strategy using cyanoacrylate tissue adhesive (CTA) in amniotic membrane transplantaton(AMT) to manage corneoscleral melting in severe ocular burns. Methods Twelve eyes from eleven patients with chemical or thermal burns of grade Ⅳ were recruited for this study.After medical treatment failed to arrest corneal or sclera melting,CTA were applied directly on the ulcerating corneal or sclera surface to augmented AMT. Results In all cases,all sclera ulcerations (five of eleven) were prevented or healed,epithelialization of burned cornea (eight of eleven) was complete,corneal ulceration in the rest three eyes was successfully arrested. Conclusion Tissue adhesive aided amniotic membrane transplantation is a promising altermnative in managing severe corneoscleral melting in chemical or thermal burns to maintain the integrity of the ocular wall.
