    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.

    The Effect of Childhood Obesity on Intraocular Pressure, Corneal Biomechanics, Retinal Nerve Fiber Layer, and Central Macular Thickness
    (Lippincott Williams and Wilkins, 2024) Aydin Eroglu, Sayime; Akyuz Unsal, Ayse Ipek; Verdi, Furkan; Kurt Omurlu, Imran; Unuvar, Tolga; Anik, Ahmet
    Précis: Elevated corneal hysteresis (CH) and resistance factor (CRF) in obese and overweight children imply weight's effect on corneal biomechanics. Increased Goldmann-correlated intraocular pressure (IOPg) in obese children indicates glaucoma risk, emphasizing screening for IOP and retinal changes. Purpose: To evaluate the effect of obesity on corneal biomechanics, retinal nerve fiber layer (RNFL), and central macular thickness (CMT) in children. Patients and Methods: In this prospective, cross-sectional, comparative study, 146 eyes of normal-weight, over-weight, and obese children aged between 6 to 17 years were evaluated. The IOPg, corneal compensated IOP (IOPcc), CH, CRF, and the average retinal nerve fiber layer (RNFL), average cup-to-disk ratio (c/d), and central macular thickness (CMT) were measured by Ocular Response Analyser and Spectral-Domain Optical Coherence Tomography (SD-OCT), respectively. Results: There was no statistically significant difference regarding age, gender, IOPcc, average RNFL thickness, c/d ratio, and CMT among the groups (P≥0.05). The IOPg was significantly higher in obese children compared with normal-weight children, while CH and CRF values were significantly higher in both obese and over-weight children compared with healthy ones (P<0.05). There was a positive correlation between BMI percentile and IOPg, CH, and CRF values. Conclusion: In our study, higher IOPg, corneal hysteresis, and corneal resistance factor values suggest that obese children could be potential candidates for glaucoma. Therefore, it would be appropriate to screen them for IOP and retinal alterations. Further investigations with larger sample size and longer follow-up are needed to understand the risk of glaucoma in obese children. © 2024 Lippincott Williams and Wilkins. All rights reserved.
