The recurrence rate of iritis is relatively high, but it is not possible to accurately estimate the recurrence rate due to the differences in each patient’s body constitution. Iritis is a common autoimmune disease of the eye. It is an inflammation of the iris and the ciliary body due to an abnormal immune system, resulting in the iris and ciliary body being attacked by the autoimmune system, and the patient will experience redness of the eye, eye pain, photophobia, tearing, and loss of vision. As the abnormality of the immune system is related to the patient’s physical condition, there is no way to cure it completely through medication, so there is always a possibility of recurrence of iritis. It’s just that the time interval for recurrence is not the same due to each person’s physique. Some patients may experience recurrence after a few months, while others may experience recurrence after decades, and there is no way to accurately calculate the recurrence rate. In general, patients should pay attention to reasonable eye use, keep clean and hygienic, and pay attention to rest to strengthen immunity to prevent recurrence of the disease. If recurrence occurs, it is recommended to consult a doctor in time.
