Vitamin D deficiency linked to worse symptoms in dry eye patients, finds study
China: Dry eye patients having vitamin D deficiency may experience less tear production and worse subjective symptoms, according to a recent study published in the journal Acta Ophthalmologica. This suggests that vitamin D deficiency might be a risk factor for dry eye syndrome.
Jing Liu, Tianjin Medical University, Tianjin, China, and colleagues conducted a systematic review and meta‐analysis to determine the association between vitamin D level and dry eye.
The researchers performed a systematic literature search using PubMed, Embase, Web of Science, and Cochrane Library databases. The studies that evaluated the association between vitamin D and dry eye were included. The random‐effect model was used to combine the results. Overall, a total of 10 studies consisting of 18919 patients were included.
