Keratitis patients suffer from a wide range of symptoms, including eye irritation, increased secretion, vision loss and other symptoms. 1. Eye irritation: Keratitis, due to inflammation, can cause pain, photophobia, tearing, eyelid spasm and other symptoms, usually after the inflammation subsides, the symptoms will be relieved. 2. Increased secretion: due to inflammation stimulation, keratitis can also lead to conjunctival congestion, increased secretion and other uncomfortable symptoms. 3. Loss of vision: Keratitis can be accompanied by different degrees of corneal clouding, so patients will have different degrees of vision loss. If the keratitis is in the central optical zone, the vision loss is more obvious. It is recommended that patients with keratitis consult a doctor to evaluate their condition and use the appropriate treatment under the doctor’s supervision.
