Ocular immunology is an area of medicine that deals with the diagnosis and treatment of inflammatory eye disorders. The patient's vision may be impaired, and in certain situations, these disorders might result in significant video loss. Uveitis, intraocular inflammation, scleritis, and iritis are examples of immunologically mediated illnesses. The eye, on the other hand, is immunologically fortunate because the allograft is accepted by the cornea.An integrated immune system on the ocular surface fights infections. In tears, conjunctiva, and even the cornea, humoral, cellular, adaptive, and innate immunity combine to provide integrated immune protection.
