Comparison of the rebound tonometer (TonoVet^®) with the applanation tonometer (TonoPen XL^®) in normal Eurasian Eagle owls (<i>Bubo bubo</i>)

Abstract

The results suggest that readings from the rebound tonometer significantly overestimated those from the applanation tonometer and that the rebound tonometer was tolerated well because of the rapid and minimal stress-inducing method of tonometry in the Eurasian Eagle owls, even without topical anesthesia. Further studies comparing TonoVet with manometric measurements may be necessary to employ rebound tonometer for routine clinical use in Eurasian Eagle owls.
