Purpose To compare crystalline lens density in obese and nonobese children. Methods A total of 40 obese (25 females) and 46 age-sex matched controls (26 females) were included in this prospective study. Children with ocular diseases (except for mild refractive errors), ocular trauma, or surgery and any systemic disorders, including diabetes, were excluded. Lens densitometry (LD), central corneal thickness (CCT), anterior chamber depth (ACD) and corneal volume (CV) were measured by Pentacam HR. Results Mean participant age was 12.0 ± 1.9 (range, 7.2-18 years) in the obese group and 11.7 ± 2.0 (range, 7.5-16.1 years) in the control group. The BMI was 29.9 ± 4.5 in the obese group and 18.7 ± 2.5 in the control group ( P  ≤ 0.05). The vertical, horizontal, and areal lens density measurements were higher in obese group than in controls ( P  ≤ 0.05). There was a positive correlation between BMI and vertical, horizontal, and areal lens density measurements. The difference in CCT, ACD, and CV was not statistically significant between groups ( P  ≥ 0.05). Conclusions There is increased lens density in the obese children compared with controls. Pentacam HR may provide objective data about lens density in children.
