Objective/aim: Corneal perforations can result from a wide variety of disorders and can lead to devastating visual sequelae. Various surgical procedures have been described to manage nontraumatic corneal perforation. Conjunctival flaps offer an important technique in dealing with such corneal emergencies. We report a modified conjunctival flap procedure referred to as superior forniceal conjunctival advancement pedicle (SFCAP) in the successful management of corneal perforation and impending corneal perforation.
Patients and methods: Out of 20 patients who underwent SFCAP for non-traumatic corneal perforation and impending perforation, 16 had corneal perforations. Perforations were secondary to acne rosacea (2), advanced bacterial keratitis (6), corneal anaesthesia(2), multiple retinal procedures (2), previous corneal grafts with a compromised ocular surface (3), and advanced Mooren's ulcer (1).
Results: The globe was preserved in all patients. In 14 of the 16 eyes with perforated corneas the pedicle stabilised. One patient, who was a chronic alcoholic, rubbed the eye during sleep detaching the pedicle a week after surgery. However, the ulcer healed and the integrity of the globe was restored. None of these patients developed secondary glaucoma or ptosis.
Conclusion: SFCAP is an appropriate procedure to manage corneal perforations and impending corneal perforations where donor material is not available and transplantation of such tissue is not suitable.
