Abstract / Zusammenfassung

Purpose: To establish reference values for Schirmer’s tear test I (STT), phenol red thread tear test
(PRT) and IOP, and to determine corneal sensitivity, the ocular surface flora and the occurrence of
ocular changes in healthy chinchillas. Methods: Eighty healthy chinchillas of different ages (6 weeks
to 11 years, mean age: 3.8 years) and genders were examined. Bacterial culturing and sensitivity testing
was induced. Tear production was obtained using the STT I (Essex Pharma, Germany) and the
PRT tear test (Menicon Pharma, France). Corneal sensitivity was determined using a Cochet-Bonnet
esthesiometer (Luneau, France). A complete ophthalmic exam was performed using slit-lamp biomicroscopy,
direct and indirect ophthalmoscopy. IOP was assessed using the TonoVet (Tiolat/Icare,
Finland). Results: Themean value of STTwas 0.5 ± 0.65 mm (wetting/min) (median 0 mm).The
mean value of PRTtest was 15.5 ± 3.21mm (wetting/15 s) (median 15mm).Themean corneal sensitivity
value was 31 ± 5.99 mm (median 30 mm). The mean IOP was 3.24 ± 1.76 mmHg (median:
3 mmHg). Ocular findings included: e.g. epiphora (16/80), caruncle trichiasis (40/80), cataracts (11/
80 bilateral, 7/80 unilaterally), prominent lens sutures (15/80), nucleosclerosis (8/80, animals older 5
years) and glaucoma (1/80). The predominating bacteria involved Staphylococcus xylosus and equorum,
Aerococcus viridans and Corynebacterium. All bacteria found were susceptible to Gentamicin.
Conclusion: Because of the small amount of tears, the PRT test is recommended for tear
measurements in chinchillas. Cataracts seem to be a frequent coincidental finding in chinchillidae.
