Abstract

Amyloidosis is a disorder of protein metabolism in which amyloid can be accumulated in various tissues of the body. Primary localized amyloidosis can affect the bulbar or palpebral conjuctiva, Tenon`s capsule, tarsus, limbus, lacrimal gland, or orbit. Especially secondary localized amyloidosis of the cornea can occur after trauma. scar, and corneal opacity or can be associated with a chronic ocular inflammatory disorder. The authors diagnosed the secondary localized amyloidosis that developed in a 53-years-old female patient who had undergone penetrating keratoplasty. The diagnosis was confirmed by hematoxylin-eosin and Congo red staining, and transmission electron microscopic examination.
