Infraorbital fat tissue volume and density changes in different age groups: Evaluation with computed tomography

We investigated senile volume and density changes in infraorbital fat to evaluate by computed tomography (CT). CT examinations of a total of 120 patients (60 males and 60 females) were included in 3 age groups: 18–29 (group 1), 30–49 (group 2), and 50 years and older (group 3). Body weight and height and BMI were recorded, and infraorbital fat tissue volume and density were measured on CT. Body weight and BMI of ≥50 years of age were significantly higher than the younger ones. In overweight and obesity groups, infraorbital fat volume increased and density decreased compared to the underweight and normal weight groups. In ≥50 years of age group, infraorbital fat volume was higher; density was lower than 18–29 years of age. Female's infraorbital fat volume was higher; density was lower than males. In each age group, the infraorbital fatty tissue density of the females was significantly lower than those in the males. There was a negative correlation between infraorbital fat volume and density. In older patients and as age groups, body weight and BMI increased, infraorbital fat volume increased, and infraorbital fat density decreased. By aging, BMI and body weight and infraorbital fat volume increased, and infraorbital fat density decreased, especially at ≥50 years of age that is thought to be one of the factors that play a role in the downward bulging of infraorbital fat tissue. Females’ higher infraorbital fat volume and infraorbital fat density may be a reason for the females’ bulging in the infraorbital fat region.
