Ophthalmic examination, Schirmer tear tests, tonometry, cornea pachymetry, histopathology and scanning electron microscopy were performed on these animals. A retrospective study was also conducted on 28 HERDA horses and 291 non-HERDA horses. Records were reviewed to compare the incidence of corneal ulceration in HERDA and non-HERDA horses over a 4-yr period. [...]
