Tenonectomy was used instead of orbital exenteration in three cases of malignant choroidal melanoma. Incompletely removed tumor nodules on the posterior sclera were observed in these cases following enucleation. Tenon's capsule containing the ball implant was removed as a whole, and the conjunctiva was saved. The procedure resulted in a socket that could be fitted with an artificial eye. Proper preparation of the surgical specimen allowed for histological study of Tenon's capsule and the tissues that had been adjacent to the site of the epibulbar tumor extensions.
