Eye Conditions and Treatment
Tearing is treated in the Cornea Service and the Comprehensive Ophthalmology Faculty Practice
Tears serve three functions: 1) to make the cornea a smooth optical surface by getting rid of small surface irregularities, 2) to keep the surface of the cornea wet to prevent damage of the cells that make up the cornea, and 3) to inhibit growth of microorganisms on the eyelids and cornea. Excessive tearing (epiphora) can either be emotional or as a result of a disorder. Excessive tears can be caused by problems with the external surface of the eye, problems of the tear drainage system or flaccid lower eyelids.
