Diurnal variations in central corneal thickness (CCT) and intraocular pressure (IOP) and their relationships were studied in healthy dogs. Central corneal thickness was measured by ultrasonic pachymetry and IOP by applanation tonometry in 16 beagle dogs. Measurements were taken every 90 min over 12 h (08:00 am to 08:00 pm). The mean CCT and IOP values obtained during the sampling period were 545.6 ± 21.7 μm (range: 471 to 595 μm) and 15 ± 2.2 mmHg (range: 10 to 19 mmHg), respectively. The CCT and IOP showed statistically significant decreases at 6:30 pm and 5:00 pm, respectively (P < 0.001). Central corneal thickness and IOP values were lower in the afternoon/evening than in the morning and were positively correlated. Both findings are important for the diagnostic interpretation of IOP values in dogs.
研究了健康犬中央角膜厚度（CCT）和眼压（IOP）的昼夜变化及其关系。通过超声测厚法测量16只比格犬的中央角膜厚度，通过压平眼压计测量眼压。在12小时内（上午8:00至下午8:00）每90分钟进行一次测量。采样期间获得的平均CCT和IOP值分别为545.6±21.7μm（范围：471至595μm）和15±2.2mmHg（范围：10至19mmHg）。CCT和IOP分别在下午6:30和下午5:00出现统计学上的显著下降（P<0.001）。下午/晚上的中央角膜厚度和IOP值低于上午，且呈正相关。这两个发现对于犬眼压值的诊断解读都很重要。
