The squinting of the eyes when the patient is dazed may be caused by eye diseases such as crypto-strabismus, intermittent exotropia and amblyopia. 1. Occult strabismus: When the brain fusion is out of control during daze, the eyeballs can not be kept in the right position, so the patient will show eye position deviation, i.e. occult strabismus. Most of the patients show the symptoms of strabismus when they are dazed and empty, and the symptoms will disappear after a little rest. 2. Intermittent strabismus: When looking at distant objects, the visual axis is separated, and the balance of the eyeball’s abduction and collection functions is out of balance, resulting in the tendency of the eyeball to be outwardly skewed. In the early stage of the disease, the eyes are only tilted outward when looking at distant objects, but with the development of the disease, the eyes are also tilted outward when looking at near objects, which is often seen when the patient is dazed, tired, drowsy, etc., and photophobia is also present. 3. Amblyopia: Amblyopia is often caused by monocular long-term strabismus, refractive error and other visual anomalies. Patients usually do not have organic lesions in the eye, but may show visual acuity and refractive error, difficulty in grading, and may also show strabismus when they are dazed and empty. It is recommended that patients who often have strabismus when they are dazed should consult a doctor in time to evaluate their condition and standardize their treatment under the guidance of a doctor.
