There are important considerations that could easily be overlooked when taking IOP estimations of wild or exotic species. Dr Antony Goodhead, the veterinary ophthalmologist and his colleagues at the Johannesburg Animal Eye Hospital in South Africa, have been fortunate to be exposed to a large variety of species and local wildlife. The TONOVET tonometer has been their instrument of choice for obtaining IOP estimations in these varied species.
Challenges in measuring IOP in wildlife
Restraint is crucial when working with wild species, both for the safety of the animal and the veterinary team. For instance, large felines often require chemical immobilisation, and even seemingly simple handling techniques can affect IOP measurements. Studies in domestic animals, such as dogs, show that improper restraint — like pressure on the jugular vein — can lead to falsely high IOP readings. This was observed in vultures, where the IOP was higher in the Lappet-faced vulture, likely due to the firmer restraint needed.
TONOVET’s advantages in wildlife tonometry
TONOVET Plus is particularly useful in quick and precise IOP measurements. Its compact probe tip works without the need for corneal anesthesia and is ideal for small or mobile animals like meerkats. For more difficult cases, such as those involving large or free-roaming wildlife, TONOVET can be used at various angles to adapt to unpredictable field conditions.
