Purpose The aim of this study was to establish normal ophthalmic parameters for selected diagnostic tests, and to describe the orbital anatomy and adnexal histology of the broad‐snouted caiman. Method A total of 35 C aiman latirostris that were free of obvious ocular diseases were used to measure the parameters in this investigation. Ages ranged from 5 to 15 years. Ophthalmic diagnostic tests were conducted, including evaluation of tear production with Schirmer Tear test‐1 ( STT 1), culture of the conjunctival bacterial flora, applanation tonometry, conjunctival cytology, nictiating membrane incursion frequency test ( NMIFT ), endodontic absorbent paper point tear test ( EAPPTT ), palpebral fissure length measurement ( PFL ) and B‐mode ultrasonography. Adnexal histology and skull samples were studied. Results Mean (± SD ) STT 1 was 3.4 ± 3.6 mm/min (95% confidence interval of 2.01–4.78 mm/min), intraocular pressure ( IOP ) was 12.9 ± 6.2 mmHg, NMIFT was 6.0 ± 3.5, EAPPTT was 17.1 ± 2.5 mm/min, PFL was 28.9 ± 3.0 mm, anterior chamber depth was 3.1 ± 0.3 mm, lens axial length was 8.4 ± 0.6 mm, vitreous chamber depth was 7.9 ± 0.7 mm and axial globe length was 19.9 ± 1.3 mm. For all animals evaluated, B acillus sp., Diphteroids and S taphylococcus sp. were predominant.
