Possibilities of ultrasound examination for assessing biometric characteristics of the lacrimal gland in normal individuals of different ages
The purpose was to determine the biometric characteristics of the palpebral and orbital parts of the lacrimal gland (LG) in normal individuals of different ages. Material and methods. A total of 120 healthy individuals (240 eyes) were examined, including 60 children (group 1) and 60 adults (group 2)...

| description | The purpose was to determine the biometric characteristics of the palpebral and orbital parts of the lacrimal gland (LG) in normal individuals of different ages. Material and methods. A total of 120 healthy individuals (240 eyes) were examined, including 60 children (group 1) and 60 adults (group 2). Depending on their age, the subjects were divided into subgroups: 1A — 20 children aged 1 to 7 years, 1B — 20 children aged 7 to 13 years, 1B — 20 children aged 13 to 17 years, 2A — 20 adults aged 18 to 40 years, 2B — 20 adults aged 40 to 60 years and 2B — 20 adults aged 60 to 90 years. Ultrasound examination (US) of the LG was performed on a multifunctional device using a linear 11–18 MHz sensor in the B-scan mode at medium-low values of the signal gain (GAIN). Results. Analysis of biometric parameters of the LG showed that the sizes of the palpebral and orbital parts of the LG depend on age. The minimum sizes of the LG were noted in children in subgroup 1A. The diameter and thickness of the palpebral part were 6.49±0.50 mm and 2.20 ± 0.13 mm, respectively, while the size of the orbital part was 9.50 ± 0.44 mm. In adults, the lowest values of biometric parameters of the LG were established in subgroup 2A, amounting to 8.48 ± 0.50 mm and 2.2 ± 0.1 mm for the palpebral part and 13.47 ± 0.48 mm for the orbital part, respectively. In the older age subgroup, the highest values of the parameters of the LG orbital part were noted, the average size of which was 16.02 ± 0.15 mm. Conclusion. The normative parameters of LG sizes differ significantly in adults and children, which must be taken into account when examining patients of different ages with suspected pathological changes in the LG. The biometric characteristics of the LG revealed by ultrasound in healthy individuals can be used as echographic criteria for diagnosing LG diseases. |
