AIM: To evaluate the repeatability and accuracy of iCare IC100 tonometer in measuring intraocular pressure(IOP)by comparing the correlation and difference with Goldmann applanation tonometry(GAT)and non-contact tonometer(NCT), and to compare the correlation of the three types of IOP measurement with the central corneal thickness(CCT).METHODS: Prospective study. A total of 90 outpatients(90 eyes)in Liaoning Aier Eye Hospital from March 2019 to May 2019 were randomly selected as study subjects. All patients were measured IOP using iCare IC100, NCT, and GAT. The interclass correlation coefficient(ICC)was used to evaluate the repeatability of IOP measured 3 times consecutively using an intraocular tonometer. The correlation and consistency of iCare IC100, GAT and NCT were compared by one-way ANOVA, Pearson linear correlation analysis and Bland-Altman analysis. The linear regression analysis was used to analyze the correlation of the three tonometers with CCT.RESULTS: The mean IOP measured with iCare IC100, GAT and NCT was 19.74±6.90, 19.88±7.07 and 18.47±6.31 mmHg, respectively(F=1.180, P=0.309). The measurements of iCare IC100 with GAT, iCare IC100 with NCT and GAT with NCT were all positively correlated(r=0.930, 0.946, 0.918, all P<0.05), the Bland-Altman analysis showed that the mean differences between iCare IC100 and GAT, iCare IC100 and NCT, GAT and NCT were -0.142±2.61, 1.27±2.24, and 1.41±2.81 mmHg, respectively, with 97%(87/90), 96%(86/90), and 97%(87/90)IOP differences distributed within their 95% confidence intervals. The IOP measured with iCare IC100 and CCT, GAT and CCT and NCT and CCT were all positively correlated(r=0.426, 0.353, 0.451, all P<0.01). The linear regression equations between iCare IC100, GAT and NCT measurement and CCT were iCare IC100 IOP=-19.62+0.074×CCT; GAT IOP=-13.54+0.063×CCT; NCT IOP=-19.65+0.072×CCT; that is, for every 10 μm increase in CCT, iCare IC100 measurement increased by 0.74 mmHg, GAT measurement increased by 0.63 mmHg, and NCT measurement increased by 0.72 mmHg.CONCLUSION: The iCare IC100 tonometer has good repeatability and accuracy in measuring IOP, and the CCT has a greater impact on the measurement of iCare IC100 than the GAT and NCT.

ObjectiveTo explore the possible mechanism of pediatric tuina therapy in treating anorexia nervosa. MethodsTotally 120 children with anorexia nervosa were randomly divided into a tuina group and a medication group， with 60 cases in each group. Sixty healthy children undergoing physical examinations were recruited as the healthy control group. Children in the tuina group received traditional pediatric tuina therapy， while those in the medication group received orally chewed Jianwei Xiaoshi tablets. Each treatment course lasted for 7 days， with a 1-day interval between courses， and a total of 4 courses were administered. Before and after treatment， seven indicators including gastric motility frequency， gastric area， gastric area 30 minutes after drinking， anterior-posterior diameter and area during gastric fundus dilation， anterior-posterior diameter and area during gastric fundus contraction were measured using a color Doppler ultrasound diagnostic instrument in children from the healthy control group， tuina group， and medication group. Additionally， gastric emptying rate at 30 minutes， changes in anterior-posterior diameter and area during gastric fundus contraction， and changes in gastric area were compared. ResultsThis study ultimately included 60 healthy children in the control group， 59 children in the tuina group， and 51 children in the medication group. Compared with the control group at baseline， the gastric area and the anterior-posterior diameter and area during gastric fundus contraction increased， while the gastric emptying rate， gastric motility frequency， and changes in anterior-posterior diameter during gastric fundus contraction decreased in both the tuina group and medication group， with only a decrease in gastric area during gastric fundus contraction observed in the tuina group （P＜0.05）. Compared with baseline， after treatment， the gastric emptying rate， gastric motility frequency， and changes in anterior-posterior diameter and area during gastric fundus contraction increased in the tuina group， while the gastric area and area during gastric fundus contraction decreased 30 minutes after treatment； in the medication group， gastric motility frequency and changes in anterior-posterior diameter during gastric fundus contraction increased， while the area during gastric fundus contraction decreased （P＜0.05 or P＜0.01）. Compared with the medication group after treatment， the gastric area decreased 30 minutes after treatment， while the gastric emptying rate and gastric motility frequency increased （P＜0.05）. ConclusionThe possible mechanism of pediatric tuina therapy in treating anorexia nervosa is to promote gastric motility and gastric emptying， thereby improving gastrointestinal dysfunction in children.
