RESUMO
PURPOSE: To clarify the usefulness of multilayer amniotic membrane transplantation in an unusual case of calcareous corneal degeneration in a patient with graft-versus-host disease. METHODS: A 20-year-old Caucasian woman had bilateral calcareous corneal degeneration of one year of evolution, secondary to graft-versus-host disease. Treatment for both eyes with topical steroids and antibiotic ointment was not successful. Right eye had a spontaneous corneal perforation, and a three-layer circle amniotic membrane graft was applied to the whole cornea. RESULTS: During a follow-up period of 20 months we observed stability of the corneal epithelium and stroma. The amniotic membrane-covered area showed rapid epithelization, reduced inflammation and suppressed fibrosis formation. CONCLUSIONS: Multilayer amniotic membrane transplantation may be considered an alterantive for reconstructing the ocular surface in a patient with severe dry eyes and calcareous corneal degeneration, even with little perforation.

Se presenta un caso de metástasis coroidea de un cáncer papilar de tiroides. La metástasis es el mecanismo más frecuente de la aparición de patología ocular maligna. Sin embargo el tumor primario más frecuente es el de la mama y del pulmón seguido por riñón, testículo, próstata e intestino. El cáncer de tiroides es raro y menos frecuente aún es que envíe metástasis a la coroides. El paciente presentaba además metástasis a huesos largos, tórax y cerebro. La lesión coroidea fue tratada con radioterapia con mal resultado
