Please can someone tell me what autoimmune tear film reaction means? is that sjrogens? or could it be somthing else?

There are a couple of articles that explain this condition which will help you to understand the condition: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3587314/ https://pubmed.ncbi.nlm.nih.gov/23360156/ I this is helpful!

Dry eyes can result from decreased (or poor quality) tear production. One of the causes of this can be an autoimmune reaction. Sjogren's syndrome can be one (but not the only) cause. Artificial tears are the mainstay of dry eye syndrome but immune modulators such as cyclosporin A are also used.
