Abstract

Complete ophthalmic examination of a mob of western gray kangaroos (Macropus fuliginosus) was performed under chemical restraint. Examination included intraocular pressure (IOP) measurement by rebound and applanation tonometry, fluorescein staining, corneal diameter measurement, slit-lamp biomicroscopy and indirect funduscopy. The corneal diameters had a mean of 19.52 mm, SD 2.16 mm, 95% confidence interval (CI) 18.71–20.32 mm. Ocular abnormalities were noted in 4/8 (50%) of examined kangaroos. Intraocular pressure as estimated by rebound tonometry was 9.00 mm Hg with a 25–75% quartile range of 6.5–10.75 mm Hg and a minimum–maximum range of 5.00–23.00 mm Hg. Intraocular pressure as estimated by applanation tonometry was 11.50 mm Hg with a 25–75% quartile range of 10.00–17.00 mm Hg and a minimum–maximum range of 9.00–20.00 mm Hg. This is the first report of ocular examination findings in a mob of captive western gray kangaroos and provides ranges and values for tonometry and corneal diameter.
