Whether or not trauma-induced pupil dilation can be cured depends on the cause of the dilation and its severity, but in some cases, timely treatment can lead to gradual recovery. There is no good treatment for trauma-induced pupil dilation, but some cases with relatively simple pathological mechanisms can be cured or improved through timely detection and treatment, such as pupil dilation or narrowing caused by post-traumatic iris adhesion, which can be improved after timely surgical release. There is also the pupil dilation caused by traumatic hematoma embedded in the pupil and other extrusion of the nerves innervating the pupil, if it can be detected in time and decompression, through a certain period of time through the nutritional recovery may be improved or even cured, but if it is a serious irreversible damage is difficult to recover. When craniocerebral trauma and other cases of pupil dilatation should be timely medical treatment, to rule out life-threatening factors, early treatment may be able to achieve better results. It is recommended that the patient go to the hospital in time to clarify the cause of the disease and follow the doctor’s instructions for treatment.
