Epitarsus is the name given to the apronlike folds of the fornix conjunctiva attached to the tarsal conjunctiva. It is mostly seen in the upper lid. Often the edge of the fold is free, allowing a probe to be passed underneath for some distance. Major Herbert1 (1901) used the term conjunctival bridge to denote the same condition.
The condition was first noted by Von Harlan and de Schweinitz2 (1895). It was fully described by Schapringer3 (1899), and thought to be a congenital anomaly, caused by adhesion of the amniotic bands to the epithelial covering of the globe. Oeller4 rejected this theory on the grounds that the epitarsus is never associated with gross malformation of the lids, usually seen with adhesions between the amniotic bands and the lids. Wibaut5 (1926) thought that it was due to a persistence of hypertrophic plica semilunaris, but as the epitarsus
