Purpose The marginal part of the tarsal conjunctiva forms a lid wiper structure that wipes the ocular surface and distributes the tear film during the blink. It was attempted to investigate whether this region of the upper and lower lid shows specific changes in several kinds of ocular surface diseases. Methods 44 eyes of patients from the outdoor department of the university eye clinic Vienna were observed by slit lamp investigation of the ocular surface, vital staining with fluorescein and lissamin green. It was focused on evaluation of the tarsal conjunctiva including the lid margin and the wiper. Vessel dilatation, teleangiectatic changes and vital staining were each designed in three stages. The patients suffered from inflammation or affections of the lid, the conjunctiva and the cornea including chemical burns, graft versus host disease and injuries Results Compared to normal eyes dilatation of vessels and staining was observed more in patents with inflammations but although in serious affections like chemical burn or injuries. Even in corneal affections changes of vessels were observed. Conclusion Changes of the wiper can be observed in several diseases of the ocular surface and may be a sign of strain in this region.
