Patient sleep rolling eyes mostly refers to incomplete eyelid closure and upturning of eyes, which may be caused by congenital physiological factors, or may be caused by epilepsy, abnormal nerve discharges and other pathological factors. 1. Physiological factors: when sleeping, there is usually an upward turning movement of the eyeballs. When some patients have incomplete eyelid closure, the sclera of the lower eye will be exposed. This is a normal physiological phenomenon and does not require treatment if it is not accompanied by other discomforts. 2. Pathological factors: Epilepsy is a neurological disorder in which patients may experience convulsions, foaming at the mouth, and other uncomfortable symptoms. If the patient’s condition continues to develop, he or she may roll his or her eyes while sleeping. Abnormal nerve discharges can easily lead to transient brain dysfunction, which in turn leads to the phenomenon of rolling eyes while sleeping. It is recommended that patients who suffer from frequent rolling of the eyes with discomfort should consult a doctor promptly to evaluate their condition and follow the doctor’s instructions for treatment.
