This study included 74 eyes of 74 patients diagnosed with primary SS. Dry eye parameters included tear breakup time, Schirmer I value, corneal staining score, conjunctival staining score, and Ocular Surface Disease Index. The serum concentration of 25(OH)D3 was evaluated. Results: The mean serum 25(OH)D3 level was 20.4 ± 8.0 ng/mL.
