An ulcer or erosion of the lacrimal apparatus (the tear-producing and tear-draining system of the eye).
From Greek 'dakryon' (tear) + 'elkosis' (ulceration). The term combines tear-related terminology with a condition involving erosion or breakdown of tissue.
This is a serious eye condition where the tear system starts breaking down—it's the kind of rare medical word that shows how specific doctors can get about eye diseases!
