RESUMO
PURPOSE: To report an eye-threatening complication associated with amniotic membrane grafting. DESIGN: Interventional case report. METHODS: Retrospective review of the clinical and surgical records of a 43-year-old man who developed melting of his corneal graft after amniotic membrane transplantation. RESULTS: Melting of a corneal graft after amniotic membrane transplantation was arrested by utilizing a tectonic, full-thickness corneal button denuded of endothelium in conjunction with a temporary tarsorraphy and systemic steroids. CONCLUSIONS: To the best of our knowledge, this is the first report of an eye-threatening complication associated with amniotic membrane grafting. Caution should be exercised in utilizing amniotic membrane in patients who have undergone multiple ophthalmologic surgical procedures, which may sensitize the ocular immune system or lead to localized ischemia.

PURPOSE: Two patients with biopsy-proven conjunctival papillomata exhibited complete resolution after treatment with topical Interferon Alfa-2b (IFNalpha2b). DESIGN: Interventional case reports. METHODS: Two patients with monocular biopsy-confirmed conjunctival papillomata were treated with IFNalpha2b, 1 million units/cc, one drop four times daily until clinical resolution was achieved. RESULTS: (Patient 1) The lesion's size was significantly reduced at 1 month. Complete resolution was noted at the 3-month visit. No recurrences were seen 40 months post-treatment. (Patient 2) The lesion completely resolved after 6 weeks of treatment. No recurrence has occurred 18 months post-treatment. No systemic or local side effect of treatment was noted. CONCLUSIONS: Two sizable conjunctival papillomata resolved using topical IFNalpha2b alone. Interferon is usually not considered effective for large solid tumors without surgical debulking. We realize that this is a limited case series, but these cases may serve as a basis for further investigation.
