Ophthalmic examination findings in adult pygmy goats (Capra hicus).
OBJECTIVE
To document normal ophthalmic findings and ocular abnormalities in captive adult pygmy goats.


METHODS
Ten healthy adult pygmy goats (five male, five female; 5-11 years of age; 26-45 kg body mass) underwent complete ophthalmic examinations.


METHODS
Direct illumination, diffuse and slit-beam biomicroscopy, indirect ophthalmoscopy, IOP measurements and Schirmer tear tests were performed. TonoVet rebound tonometry, followed by topical application of 0.5% ophthalmic proparacaine, and Tono-Pen XL applanation tonometry were performed in each eye to obtain estimates of IOP.


RESULTS
Ophthalmic abnormalities included corneal scars and pigmentation, incipient cataracts, lenticular sclerosis, and vitreal veiling. Mean STT values were 15.8 mm/min, with a range of 10-30 mm/min. Mean IOP values were 11.8 mmHg for TonoVet-D, with a range of 9-14 mmHg; 7.9 mmHg for TonoVet-P, with a range of 6-12 mmHg; and 10.8 mmHg for Tono-Pen XL, with a range of 8-14 mmHg.


CONCLUSIONS
Ophthalmic examination findings in adult pygmy goats, including normal means and ranges for STT and IOP measurements, using applanation and rebound tonometry, are provided.
