RESUMEN
OBJECTIVE: To establish reference values for ophthalmic tests in two bat species. BATS: Fourteen bats including seven great fruit-eating bats (Artibeus lituratus) and seven tailed tailless bats (Anoura caudifer). PROCEDURES: Normal values for following ophthalmic tests were investigated as follows: (a) aqueous tear production using the standardized endodontic paper point tear test (EPPTT), (b) rebound tonometry, and (c) horizontal palpebral fissure length. RESULTS: Aqueous tear production was 2.53 ± 1.65 mm/min for A lituratus and 1.89 ± 0.62 for A caudifer. Intraocular pressure measured in the upright position was 11.0 ± 3.28 mm Hg for A lituratus and 7.28 ± 2.70 for A caudifer. Horizontal palpebral fissure length was 5.04 ± 0.45 mm for A lituratus and 3.92 ± 0.51 for A caudifer. CONCLUSIONS: The data obtained in the present study may serve as a reference for ophthalmic parameters and help practitioners in the diagnosis and management of eye diseases in bats, as well for future investigations about microchiroptera bats.
