Sulcus subtarsalis
Groove inside the eyelid
From Wikipedia, the free encyclopedia
Sulcus subtarsalis is a groove in the inner surface of eyelid near the eyelid margin and which is also parallel to it.[1] This separates marginal conjunctiva from tarsal conjunctiva. It provides space for lodging of foreign bodies. Arlt's line is a linear line present in the sulcus subtarsalis in Chlamydia trachomatis infection.[2]
