Comparison of vitamin D levels between patients with pterygium and healthy subjects

Evaluation of 25-Hydroxyvitamin D levels in patients with dermatochalasis

PURPOSE

To compare serum 25-hydroxyvitamin D (25(OH)D) levels of patients with dermatochalasis who underwent upper lid blepharoplasty and healthy controls.

METHODS

This retrospective comparative study included dermatochalasis patients who underwent upper lid blepharoplasty and age-and sex-matched controls from January 2019 to January 2021. The data, including comprehensive ophthalmological examination, internal medicine outpatient examination, and laboratory results of the dermatochalasis patients and healthy controls, were collected from the electronic patient records. Serum 25(OH)D, creatinine, calcium (Ca), phosphate (P), triglyceride (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels were evaluated and compared between the dermatochalasis patients and healthy controls.

RESULT

Of our participants, consisting of 46 patients with dermatochalasis and 52 healthy controls, 54 (55.10%) were female and 44 (44.90%) were male. A statistically significant difference was observed in vitamin D levels between the healthy and dermatochalasis groups (p ≤ 0.001). The percentage of individuals with vitamin D deficiency (< 20 ng/mL) was significantly higher in the dermatochalasis group (p = 0.001). In addition, the percentage of individuals with severe vitamin D deficiency (< 10 ng/mL) was again significantly higher in the dermatochalasis group (p = 0.001). The risk of dermatochalasis incidence was found to increase in cases of low vitamin D (OR = 1.210; p = 0.017).

CONCLUSION

Low serum 25(OH)D levels may play a role in the etiopathogenesis of dermatochalasis. Future research should include longitudinal studies and prospective clinical studies to investigate the mechanism responsible for the low vitamin D observed in dermatochalasis patients.
