Children with poor eye closure are mainly associated with short upper eyelids, facial paralysis, traumatic brain injury, etc. Further examination is recommended to clarify the cause and treat accordingly. 1. Short upper eyelid: the upper eyelid is too short due to congenital developmental reasons, which leads to poor eye closure, it is a normal physiological phenomenon, and there is no need to worry too much. 2. Facial paralysis: damage to the facial nerve leads to paralysis of the facial muscles, thus causing poor eye closure, usually accompanied by facial muscle asymmetry, sensory abnormalities and other symptoms, which can be treated with medication, such as prednisone, prednisolone, etc., to promote the recovery of the nerve damage and control the condition. 3. Traumatic brain injury: head injury caused by external factors, stimulate the nerves in the brain, resulting in sleeping with poorly closed eyes, accompanied by lethargy, limb weakness, babbling and other symptoms. All of the above drugs should be used under the guidance of a doctor, and should not be used blindly on their own to avoid aggravating the condition.
