Applanation tonometry was used to estimate intraocular pressure (IOP) and Schirmer tear test (STT) I was used to estimate tear production in both eyes of 12 juvenile elands (Taurotragus oryx) and one eye each of 15 Asian fallow deer (Dama mesopotamica). Mean (± standard deviation) IOP was 14.6 ± 4.0 mm Hg in the eland and 11.9 ± 3.3 mm Hg in the deer. Mean tear production was 18.7 ± 5.9 mm/min in the eland and 10.5 ± 6.5 mm/ min in the deer. The large variation in IOP between two members of the family Bovidae, the elands reported here and the Thomson gazelle (Gazella thomsoni) for which we previously reported a mean pressure of 7.6 mm Hg, illustrates the need to establish reference values for each species. Tear production may be influenced by the species' natural habitat.
