iridodialyses

An iridodialysis is a medical condition affecting the eye, specifically the iris. It occurs when the iris, the colored part of the eye that controls pupil size, detaches or tears from its ciliary body attachment. This detachment can happen due to trauma, such as a direct blow to the eye, or in some cases, it can be a congenital defect. The appearance of an iridodialysis can vary depending on the extent of the tear. It may manifest as a crescent-shaped notch in the iris margin or a larger section of the iris pulled away from its normal position.

When an iridodialysis occurs, it can lead to several symptoms. Patients may experience double vision, also known as diplopia, because the pupil may no longer be able to constrict or dilate properly, creating an irregular pupil shape. Light sensitivity, or photophobia, is another common symptom, as the irregularly shaped pupil may allow more light to enter the eye than usual. Blurred vision can also occur. In many cases, a smaller iridodialysis may not cause significant visual impairment, but larger tears can lead to more pronounced visual disturbances.

The diagnosis of an iridodialysis is typically made during an eye examination by an ophthalmologist. They will look for the characteristic appearance of the detached iris. Treatment for iridodialysis depends on the severity of the condition and the symptoms it causes. Mild cases that do not significantly impact vision may not require treatment and can be monitored. For more severe cases causing bothersome symptoms like diplopia or significant visual impairment, surgical intervention may be considered to reattach the iris.
