Failure to turn the eyeball may be due to damage to the oculomotor nerve, or trauma, endocrine abnormality, etc. 1. Damage to the oculomotor nerve: For example, if the oculomotor nerve is damaged by aneurysm or inflammation, resulting in complete paralysis, the movement of the eyeball is limited in all directions, and the eyeball cannot turn. Mostly accompanied by ptosis, mild protrusion of the eyeball and other symptoms. 2. Trauma: especially fractures near the orbit, such as extraocular muscle embolism caused by orbital burst fracture, which causes abnormal muscle movement and limitation of eye movement, and may show that the eyeball can not rotate. 3. Endocrine diseases: for example, thyroid-related eye diseases, due to abnormalities in thyroid stimulating hormone, causing abnormal differentiation of orbital stem cells to fat cells. This can lead to degeneration or fibrosis of the eye tissues, causing eye discomfort, eyeball protrusion and eye movement disorders. There are many reasons why the eyeballs do not rotate. It is recommended to consult a doctor for further examination to identify the cause and to provide targeted treatment or therapy.
