OPHTHALMIC EXAMINATION IN COMMON KESTRELS (FALCO TINNUCULUS) FROM SOUTH KOREA

The purpose of this study was to establish reference ophthalmic findings in the common kestrel (Falco tinnunculus). Twenty healthy adult kestrels were included in this study. Ophthalmic examinations included slit lamp biomicroscopy, fundus exam, Schirmer tear test, conjunctival bacterial culture and isolation, corneal touch threshold, tonometry, and corneal diameter measurement. Mean tear production was 7.4 ± 3.27 mm/min, and mean intraocular pressure measured via applanation tonometry was 10.5 ± 3.15 mm Hg. In addition, the mean corneal touch threshold was 29.8 ± 20.1 mm, and the mean corneal diameter was 9.8 ± 1.1 mm. Of the 25 conjunctival swabs, 23 (92%) yielded bacterial growth. Most of these bacteria were gram positive (69.6%); the most predominant genus was Staphylococcus. This study presents reference values for ophthalmic examinations in common kestrels.
