Its products are an excellent complement to Revenio's product portfolio, which is focused on tonometry. The illustrative combined net sales of Revenio and CenterVue for 2018 amounted to EUR49.3m.
Among their topics are Doppler echocardiography and color flow imaging: comprehensive noninvasive hemodynamic assessment, right heart assessment and pulmonary hypertension, native valvular heart disease, cardiac tumors and masses, vascular tonometry and imaging for cardiovascular risk assessment, and artificial intelligence and echocardiography: current status and future directions.
Therefore, the TonoVet rebound tonometry under the 'd' mode is a reliable method for measuring IOP in pigeons.
To confirm diagnosis, IOP was first measured with a non-contact tonometer, followed by Goldmann applanation tonometry. As the IOP met the National Institute for Health and Care Excellence guidelines for referral, the patient was informed about the reason for referral and the complications that can arise if a referral is not made.
In healthy subjects, the increase in IOP between sitting and supine position was reported as 1.8 mmHg using Perkins applanation tonometer, 2.5-3.9 mmHg with pneumotonometer, 1.2 mmHg with Tono-Pen, and 4.1 mmHg with Goldman applanation tonometry. (1,26,27,28,29) Mosaed et al.
Other reference values for applanation and rebound tonometry are described in tables 2 and 3, respectively.
Participants underwent monthly ophthalmic examination for: (a) intraocular pressure (IOP) monitoring via Goldmann Applanation Tonometry, (b) adverse event monitoring, (c) standardised BCVA assessment in ETDRS letters and (d) colour fundus photography.
Arterial stiffness was measured using pulse wave analysis based on non-invasive oscillometric tonometry. Various confounding factors, including body fat percentage and systolic blood pressure, were controlled for in the analyses.
Kim, M.D., from Emory University in Atlanta, and colleagues studied freshman ASF participants and non-athletic undergraduate controls with repeated measures echocardiography and applanation tonometry before and after one competitive season.
Subjects were excluded if they had allergies to botulinum toxin or any component of the drug; previous eyelid, refractive, or intraocular surgery; any abnormality preventing reliable tonometry in either eye; strabismus; contact lens wear; pregnancy; glaucoma; and ocular hypertension and are using agents that could interfere with neuromuscular transmission.
