An association of polymorphic marker rs2228262 in the THBS1 gene with the risk of developing dry eye in Sjögren syndrome was revealed. Confocal microscopy data suggest that this polymorphic marker is responsible for the high probability of corneal nerve fiber lesion in Sjögren syndrome even in the absence of clinical and functional signs of dry eye syndrome. A significant correlation was established between polymorphic markers rs1478604, rs2228262 in THBS1 gene and the coefficients of anisotropy and orientation symmetry of corneal nerve fibers. These results allow considering these polymorphic markers as a genetic factor of predisposition to dry eye syndrome in patients with Sjögren syndrome.
