Keratitis may cause patients to experience rainbow circles when looking at things.
Rainbow rings are called iridescence and are a common ophthalmologic condition, usually caused by corneal edema that scatters light as it is refracted. Glaucoma is the most common cause of corneal edema, but when a patient has keratitis, inflammation can also cause corneal edema, resulting in irises.
It is recommended that patients with keratitis should go to the ophthalmology department of the hospital in a timely manner, and be clearly diagnosed by the doctor by doing slit lamp microscopy, etc., and take targeted treatment to control the inflammation as soon as possible, and eliminate the symptoms by ordering antibiotic drops in the eye, such as ofloxacin eye drops and tobramycin eye drops.
