cholecalciferol and Dry-Eye-Syndromes

To assess the effect of oral vitamin D. Liuzhou Worker's Hospital.. This prospective study included 90 patients selected between January and December in 2019, who underwent FS-LASIK operation in our hospital and had obvious symptoms indicating dry eyes 1 month after operation. The subjects were randomly divided into two groups: The experimental group (n = 45) received vitamin D3 2000 IU/D continuously for 12 weeks; the control group (n = 45) did not take vitamin D3 orally. Ocular surface disease index (OSDI), Tear breakup time (TBUT) and Schirmer's test I were evaluated premedication and 1,3,6 months after treatment. Serum vitamin D3 level and the mean concentration of cytokine IL-6, IL-17, IL-23 in t ears were also measured.

Dry eye is a prevalent disorder of tear film resulting from either decreased tear production or increased tear evaporation. It is becoming a serious issue due to its disturbing symptoms, which become progressively troublesome affecting the work efficiency of patients and increasing financial burden due to lifelong dependency on eye drops. If not detected early, it can lead to sight-threatening complications. This study aims to explore serum vitamin D3 deficiency as a causative factor of dry eye.. The study was conducted in the outpatient department of a tertiary care hospital in India, for a period of two years from September 2018 to September 2020. About 40 patients who had dry eye and 20 controls were enrolled in this study. They were given an Ocular Surface Disease Index (OSDI) questionnaire, examined for signs of dry eye on slit lamp with Schirmer's test and tear film break-up time. All 60 participants were subjected to serum vitamin D3 level laboratory test and its deficiency prevalence was correlated with dry eye and its severity.. Serum vitamin D3 deficiency was found to be more prevalent in patients with dry eye. There was no gender predilection or change in prevalence with increasing age. Vitamin D3 level was negatively correlated with OSDI and positively with Schirmer's test 1 and 2 and tear film break-up time (TBUT) scores. Conclusion: The prevalence of vitamin D3 deficiency was not consistently found to be associated with the increasing severity of dry eye.

This study investigated the effect of vitamin D supplementation in patients with dry eye syndrome (DES) refractory to conventional treatment with vitamin D deficiency. A total of 105 patients with DES refractory to conventional treatment and vitamin D deficiency that was treated with an intramuscular injection of cholecalciferol (200,000 IU). Serum 25-hydroxyvitamin D (25(OH)D) levels were measured. Eye discomfort was assessed using ocular surface disease index (OSDI) and visual analogue pain score (VAS). Tear break-up time (TBUT), fluorescein staining score (FSS), eyelid margin hyperemia, and tear secretion test were measured before treatment, and 2, 6, and 10 weeks after vitamin D supplementation. Mean serum 25(OH)D level was 10.52 ± 4.61 ng/mL. TBUT, and tear secretion test showed an improvement at 2 and 6 weeks after vitamin D supplementation compared to pretreatment values (p < 0.05 for all, paired t-test). Eyelid margin hyperemia and the severity of symptoms showed improvement at 2, 6, and 10 weeks after vitamin D supplementation (p < 0.05 for all). Compared to pre-treatment values, FSS, OSDI and VAS were decreased at 2 weeks (p < 0.05 for all). In conclusion, vitamin D supplementation is effective and useful in the treatment of patients with DES refractory to conventional treatment and with vitamin D deficiency.
