Purpose
To compare serum thyroid hormone, vitamin B12, vitamin D3, folic acid, and ferritin levels between pediatric chalazion patients and healthy children.
Methods
Under 18-year-old chalazion patients and age- and sex-matched healthy controls were included into this retrospective case–control study. The peripheric blood sampling results obtained within six months from ophthalmological examination were investigated for statistical analysis. Free triiodothyronine (FT3), free thyroxine (FT4), thyroid-stimulating hormone (TSH), vitamin B12, vitamin D3, folic acid, and ferritin levels of the chalazion and control groups were compared.
Results
The male-to-female ratio was 8/28 in the chalazion group and 22/48 in the control group (p > 0.05). The mean age was 13.891 ± 3.924 years (3–17) and 12.346 ± 3.963 years (4–17) in the groups, respectively (p > 0.05). The mean time between ophthalmological examination and peripheric blood sampling was 3.012 ± 2.201 months (0–6) and 2.092 ± 1.906 months (0–6) in the groups, respectively (p > 0.05). The mean value of ferritin was 18.641 ± 8.971 μg/L (5.900–38.600) in the chalazion group and 35.455 ± 24.561 μg/L (11.850–106.100) in the control group (p = 0.019). The mean values of FT3, FT4, TSH, vitamin B12, vitamin D3, and folic acid levels were similar between the groups (p > 0.05 for all).
Conclusion
This study reports that pediatric chalazion patients have lower serum ferritin level than healthy children.
