title: Dacryops in the setting of a Boston type II keratoprosthesis.
abstract: Dacryops of the lacrimal tissue can develop under diverse circumstances. Recent evidence suggests that scarring or obstruction of the lacrimal ducts may lead to their dilatation and formation of a cystic structure. Patients who undergo repeated orbital surgery may therefore be at greater risk of dacryops formation. In this report, a patient who underwent multiple corneal and glaucoma procedures including Boston type II keratoprosthesis, after acid burns to both eyes, is described. Over time, a fluid-filled collection developed in the lower orbit. On surgical exploration and incision, fluid was drained from a cystic lesion which abutted the lacrimal gland and spanned the upper and lower orbits. The lesion was removed and was proven by histopathology and immunohistochemistry to be dacryops. This is the first known case of dacryops associated with Boston type II keratoprosthesis.
