[Fornix reconstruction in ocular pemphigoid with Goretex surgical membrane].

UNLABELLED: After separation of symblepharons in ocular pemphigoid, transplantation of nasal or bucal mucosa is recommended to prevent recurrent lid fusion; however, it is not always successful.

BACKGROUND

An 86-year-old patient was referred to our eye clinic because of trichiasis in ocular pemphigoid. In the right eye, the only functional eye, fusion of the lower lid and the globe was present. There was severe trichiasis with multiple lesions of the cornea and beginning neovascularization. The left eye showed complete fusion of the lid fissure and neovascularization of the cornea. To prevent the right eye from suffering the fate of the left, we tried to find a simple surgical method that could easily be performed on the multimorbid patient.

METHOD: Under parabulbar anesthesia we separated the lower lid from the globe until free passive motility of the lower lid was achieved. A cut-to-size piece of Gore-Tex surgical membrane was prepared and fixated with resorbable u-sutures on the inner lid. The membrane was left in place for 4 weeks until suture lysis. A silicone tube, which was transitorily fixed to the outer lower lid, had an additional ectropionizing effect. Three months later, lower-lid ectropion surgery was performed, combined with tarsectomy to obtain a long-term effect.

RESULT: Six months later the lower-lid fornix had stabilized, and the lid and globe had good motility. The corneal lesions had healed.

CONCLUSION

The use of 0.1 mm membrane prevents penetration of cell because of the microstructure. Similar to the "bare sclera" technique, which is used in selected cases in strabismus or pterygium surgery, the inner lid and sclera were epithelialized separately from the remaining conjunctiva. The surgical membrane prevented recurrence of the symblepharon. We think the presented technique is an easy, quick method of preventing recurrence of lid fusion after separation of symblepharons.
