Abstract

Dry eye (DE), especially severe DE (SDE), can cause ocular surface defects and reduce the patient's quality of life. Several clinical studies have shown that 0.1% cyclosporin A cationic emulsion (CsA CE) could decrease corneal damage. However, no experimental study has reported the effect of 0.1% CsA CE on SDE. The present study aimed to compare the efficacy of 0.1% CsA CE with that of 0.05% CsA emulsion for ocular surface damage and inflammation in the cases of murine DE with different severities. Following exposure to desiccating stress and subcutaneous injection of scopolamine for 5 days, C57BL/6 female mice were divided into SDE and non‑SDE (NSDE) groups based on corneal fluorescein staining scores (CFSs). Mice from both groups were topically treated with 0.05% CsA emulsion or 0.1% CsA CE for 10 days. The results demonstrated that 0.1% CsA CE‑treated mice in the SDE and NSDE groups exhibited significant improvements in all the clinical and experimental parameters. Furthermore, the CFS of 0.1% CsA CE‑treated mice in the SDE group was lower compared with that of the 0.05% CsA‑treated mice. In addition, in the SDE group, 0.1% CsA CE‑treated mice had significantly lower levels of nuclear factor‑κB activation, inflammatory infiltrations and apoptosis on the ocular surface, and they also exhibited higher conjunctival goblet cell density compared with the 0.05% CsA‑treated mice. In summary, these findings indicated that 0.1% CsA CE was more effective than topical 0.05% CsA emulsion at improving corneal epithelial injury and decreasing the levels of inflammatory cytokines and T cells in mice with SDE.
