The IOP (intraocular pressure) should not only be measured in the cases of red eyes, but also in the cases of corneal edema, orbital diseases and a history of glaucoma or lens luxation in the opposite eye. Too high or too low pressure can cause by a variety of serious ocular diseases. Increased IOP, glaucoma, is a common eye disease in dogs, cats and horses and usually causes irreversible blindness and painful. Certain breeds of dog are commonly affected by glaucoma, but any dog – mixed or purebred – can be affected. One of the procedures that principally useful in diagnosis of glaucoma is tonometry. Tonometry is the measurement of IOP and there are 3 basic methods of tonometry that can be used to measure IOP in animals: indentation tonometry, applanation tonometry and rebound tonometry. TONOVET, the basic and reliable equipment, is the rebound tonometry with a magnetized probe that bounces off the cornea when the cornea touched the probe. This device is easy to use and does not require topical anesthesia nor calibration. In conclusion, the IOP should be measured in all patients presented for ophthalmic examination.
We purchased our TONOVET several years ago primarily for equine work. It's easy, accurate, fast and not probe to artifact. We then started to use it on cats. They are a species that don’t tolerate exam room insults. The greatest insult to a cat is topical anesthesia. It stings when it goes in and the exam is over! Cats tolerate pressure checks with the TONOVET. Birds, reptiles, tortoises and other exotics are the same. Our technicians perform most of the tonometery and much prefer the TONOVET rebound tonometry on all species because of the reliability and lack of artifact. We will be moving to rebound tonometry as a sole means of pressure assessments. I am a convert.
The TONOVET is unreservedly the best tonometer I have used. It is so easy to use and the animals hardly even notice the tonometry. No topical anaesthetic is required, head positioning is not critical and restraint required is minimal. It can be used on patients post surgery when the eye is very tender, and even in the waiting room. Results are consistent and reliable. It is easy to use the TONOVET on almost every patient, even aggressive ones, and because it is so easy to use we use it on nearly all our patients, with the result that we are now diagnosing glaucomas in patients with normal looking eyes that we would not have bothered to performed tonometry on in the past. I can highly recommend the TONOVET.
I have been using the TONOVET for several years after switching from using a tono-pen. I find the TONOVET to be much easier to use and feel that it gives much more consistent results. It is particularly useful in cooperative patients as it requires minimal restraint to use. TONOVET is ideal for general practice use as it is so user friendly and do not require very frequent use to be able to use accurately.
TONOVET is easy to use, it is good value for the money.
Have used the TONOVET many times and it is very user friendly and find that the animals are less agitated with the use as well. Very fast to use and easy to learn how to use. I recommed this product to everyone!
In our equine practice, the Tonovet has been very helpful with the ‘abnormal’ eye. I do not have to do nerveblocks or topical numbing to get an accurate reading, and I rearely need to tranqualize a patient. Easy to use and consistent results once you are comfortable using it.
Since purchasing the Tonovet we use it on every exam whether it is a routine exam or not. We feel it creates value and impresses the client. I would say 95% of both dogs and cats tolerate it very well. We have diagnosed borderline glaucoma several times without clinical signs.
We’ve had our TONOVET for over 2 years now and use it regularly with confidence. The cats and dogs don’t mind it all. I often take five measurements and record the average result but find that there is very good reproducibility with the measurements. I am currently rechecking a dog that was referred for bilateral cataracts surgery. It wouldn’t be possible for me to do the rechecks without the TONOVET!
I worked in private practice for 10 years before making the (long overdue) decision to purchase a TONOVET. I can honestly say this was a medically and economically smart decision. Having a TONOVET allows me to practice better veterinary medicine and ultimately provides my patients with better veterinary health care. I find myself checking IOPs on far more at risk/suspect patients than I had in the past. Looking back, I can hardly believe I even practiced without one. I would strongly recommend that a TONOVET be a part of the basic core equipment at any veterinary practice.
