Symptom 1: upper eyelid skin relaxation: common symptoms of blepharoptosis, patients with blepharoptosis affect vision. In daily life, many elderly people because of human aging, skin relaxation will also occur ptosis, is morbid, easy to be mistaken for eye muscle weakness. So whether blepharoptosis belongs to myasthenia gravis should be differentiated by the inner upper eyelid margin.

Symptom 2: dyskinesia of eyeball rotation: each eyeball shell is attached with six extraocular muscles and tendons to manage its flexible rotation in all directions and the parallel and coordination of binocular rotation. About two thirds of patients with myasthenia can be accompanied by dyskinesia of different degrees. The more serious cases are basically fixed and fixed eyeballs, which must be binocular; In some severe cases, the two eyeballs may protrude slightly forward. The cause is unknown, but it is not accompanied by hyperthyroidism, and there is no tumor in the orbit.

Symptom 3: strabismus: eye movement disorder can be accompanied by strabismus, or not. Most patients with myasthenia are not inclined. A few patients have mild monocular exotropia, and even fewer eyes. Some patients have one eye in the right position and the other eye deviates from the upper or inner part of the eye. The lower limbus of the cornea of both eyes is not at the same level. If it occurs in children, the upper and outer part of the strabismus is covered by the upper eyelid, which affects the development of vision And later can become amblyopia, other strabismus after a long time may also be amblyopia.
