摘要: Objective To evaluate the effect of central corneal thickness (CCT) on measurement intraocular pressure (IOP) with rebound (TonoVet®) and applanation (TonoPen XL®) tonometers in beagle dogs. Animal studied Both eyes 60 clinically normal dogs were used. Procedures The IOP was measured by TonoVet®, followed TonoPen XL® half dogs, while other reverse order. All CCT measurements performed 10 min after use second tonometer. Results mean value TonoVet® (16.9 ± 3.7 mmHg) significantly higher than (11.6 ± 2.7 mmHg; P < 0.001). values obtained both correlated regression analysis (γ2 = 0.4393, Bland–Altman showed that lower upper limits agreement between two devices −0.1 +10.8 mmHg, respectively. 549.7 ± 51.0 μm. There a correlation readings (TonoVet® : P = 0.002, P = 0.035). equation demonstrated for every 100 μm increase CCT, there an elevation 1 2 mmHg respectively. Conclusions would be affected variations CCT. Therefore, should considered when interpreting dogs.
