Corneal Biomechanical Changes of Allergic Conjunctivitis

By measuring and comparing the corneal biomechanical parameters of normal people, patients with allergic conjunctivitis, keratoconus, whether allergic conjunctivitis causes changes in corneal biomechanics can be explored, and sensitive mechanical indicators of allergic conjunctivitis can be identified. Furthermore, through rubbing frequency, ocular allergic symptom scores and physical sign scores observation, corneal morphological parameters, corneal epithelial thickness, tear inflammatory cytokines levels, and conjunctival microvascular parameters measurements, related factors affecting corneal biomechanics in patients with allergic conjunctivitis can be identified. Otherwise, by comparing corneal biomechanical changes in vernal keratoconjunctivitis before and after drug treatment, biomechanical change tendency during treatment can be clarified.
