Comparison of toll-like receptor-4 (TLR-4), total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), arylesterase (ARE) levels between patients and controls. Conjunctival epithelium and PBMC TLR-4 levels were significantly higher in patients with OR compared with the controls (p < 0.001). Serum and tear TAS, TOS, OSI, and ARE levels were significantly different between patients with OR and the controls (p < 0.001).
