The inability to lift the upper eyelid may be related to eye trauma, facial nerve palsy, brain disease, myasthenia gravis and other causes. 1. Ocular trauma: If the patient suffers from ocular trauma resulting in upper eyelid bruising and edema, the upper eyelid cannot be lifted, which may be accompanied by eye pain and other uncomfortable symptoms. 2. Facial nerve palsy: As the patient’s facial nerve is damaged or inflamed, resulting in facial nerve palsy, the patient’s facial muscle movement function is lost, and the patient may not be able to lift the upper eyelid. 3. Brain diseases: patients with brain diseases such as cerebral hemorrhage may also have difficulty in lifting the upper eyelid, which may also be accompanied by hemiplegia. 4. Myasthenia gravis: Myasthenia gravis patients have fluctuating weakness of the eye, respiratory, and limb muscles, which may result in the inability to lift the upper eyelid, and in severe cases, respiratory distress may even occur. It is recommended that patients who cannot lift their upper eyelids should consult the hospital in time to assess their condition and under the guidance of the doctor for standardized treatment.
