Validation of Interleukins and Other Cytokines Together With OCT Imaging for Rapid Infectious Keratitis Assessment

Samples will be collected by conjunctival lavage of the affected eye without topical anesthesia. Sterile normal saline will be infused at room temperature into the lower conjunctival sac by gently pulling down the lower eyelid and with a needle-free insulin syringe. After few seconds, the lavage fluid will be aspirated back into the same syringe without the syringe touching the conjunctiva.
