Bilateral Increase of Matrix Metalloproteinase-9 Expression in Tears After the Unilateral Decrease of Corneal Sensitivity

Conclusions: Patients with the unilateral neurotrophic keratitis demonstrated a significant bilateral increase of the MMP-9 expression in the tear film as compared with controls. Despite the tearing reflex and corneal surface barrier being preserved in the unaffected contralateral eyes, it is necessary to pay attention to the possible attenuation of meibomian gland function in the opposite eyes as well.
