Inflammatory cytokine expression on the ocular surface in the Botulium toxin B induced murine dry eye model.

Abstract

BTX-B induced mouse model showed decreased aqueous tear production, increased corneal fluorescein staining, and TNF-alpha and IL-1beta increased expression on the ocular surface within one month. The patterns seen appeared to mimic those in humans with non-Sjögren's syndrome keratoconjunctivitis sicca (NS-KCS).
