Abstract:
Objective To investigate the effects of body mass index (BMI) on 24-hour intraocular pressure (IOP) fluctuations in adolescences.Methods Totally 90 healthy adolescences were included in the study.Measurements of 24-hour IOP were obtained by Goldmann applanation tonometer on 5:00 am,7:00 am,10 ∶ 00 am,2:00 pm,6:00 pm and 10:00 pm.BMI was calculated as weight in kilograms divided by the square of height in meters (kg · m-2).The patients were divided into three groups according to BMI,and they were Group 1 (BMI ＜ 25 kg · m-2),Group 2 (25 ≤ BMI ＜ 30kg · m-2),Group 3 (BMI ≥ 30 kg · m-2).Data were analyzed by statistic software SPSS 22.0.Results The mean of IOP,peak IOP,valley IOP and fluctuation value of IOP were (16.72 ±3.30)mmHg (1 kPa =7.5 mmHg),(19.26 ±3.68)mmHg,(14.29 ±3.26)mmHg and (4.98 ± 1.91)mmHg,respectively.And there was no significant differences in the fluctuation value of IOP among the three groups (all P ＞ 0.05);the differences in mean IOP,peak IOP,valley IOP between group 1 and group 3 were significant (all P ＜0.05).However,the differences between group 1 and group 2,group 2 and group 3 showed no significant differences (all P ＞ 0.05).Pearson correlation analysis showed that BMI was positively correlated with mean IOP and peak IOP (both P ＜ 0.05).Conclusion In the adolescent population,individuals with higher BMI tend to have higher mean IOP and peak IOP.
