Objective: To compare intraocular pressure (IOP) and central corneal thickness (CCT) of normal, overweight, and obese children and evaluate the effects of body mass index (BMI) on IOP and CCT. Materials and Methods: In this prospective, cross-sectional study, children aged 6 to 18 years without any ocular disease were included. IOPs and CCTs were measured with a non-contact air-puff tonometer (NCT) and optical coherence tomography (OCT), respectively. According to their BMI, children were divided into three groups as follows: group1 (normal), BMI <= 85; group 2 (over-weight), BMI 86-94; group 3 (obese), BMI >= 95. The IOP and CCT measurements of these groups were compared. Results: Of all 73 patients (43 males, 30 females), 146 eyes were investigated in this study. The mean of IOP was 15 +/- 2.89, 16.50 +/- 3.10 and 19.50 +/- 4.15 mmHg in group 1 (n=62), group 2 (n=24) and group 3 (n=60), respectively (p<0.001). IOP was significantly higher in obese girls than in normal weight girls (20 +/- 3.82 mmHg, 15 +/- 2.50 mmHg, p<0.01). BMI and age had a significant effect on IOP (p=0.048 and p=0.025). A 1 standard deviation increase in BMI and age increased IOP of 0.175 and 0.187 mmHg, respectively. Conclusion: In our study, IOPs measured with NCT were significantly higher in obese children, especially in girls, compared to normal and overweight children. Since the increase in intraorbital adipose tissue may lead to increased episcleral venous pressure resulting in increased IOP and impaired ocular perfusion, IOP measurements should be carefully evaluated in obese children.
