Upper eyelid muscle weakness is generally more difficult to improve with training, and patients need to be treated with medication and surgery to improve symptoms. Upper eyelid muscle weakness usually refers to the weakness of the levator muscle, resulting in the inability to raise the upper eyelid to its normal position, known as ptosis, which can affect the patient’s appearance. If the condition is severe, the upper eyelid may cover the pupil area, which can affect vision. Patients with myasthenia gravis can develop ptosis, which can be treated with oral medications such as neostigmine to restore the strength of the levator muscle. Ptosis caused by paralysis of the levator ani muscle is generally not well treated with medication, and can be treated with surgery, such as frontalis muscle suspension, levator ani muscle shortening, and so on. It is recommended that patients with ptosis consult a doctor to evaluate their condition and follow the doctor’s instructions.
