STING1 and dry eye syndrome: Although there is no clear evidence to show whether the cGAS-STING pathway is involved in dry eye, based on the current research, we speculate that the cGAS-STING pathway may be a new mechanism that causes dry eye, and targeting the cGAS-STING pathway might be potential therapeutic strategy, which could pave the way for precision treatments and drug development of dry eye and is worthy of further study.
