It is possible that keratitis can lead to iridophthalmia. Keratitis can be accompanied by red eyes, which means that the eyes are congested, and even increased discharge from the conjunctival sac and red eyes can occur as well. If there is a lot of discharge, corneal ulcers or corneal scarring appear can trigger iris. Once keratitis appears, more than simply using eye drops for corneal inflammation, it is also important to find the cause of the disease and treat it according to the pathogenic microorganism detection correspondence and active antipathogenic treatment. Because keratitis can seriously affect the patient’s vision and cause irreversible visual impairment, and later may cause corneal cloudiness, opacification or leukoplakia causing iridopia, it is important to actively pursue treatment to ensure corneal transparency and integrity.
