What causes eyeballs?

Exophthalmos may be related to myopia, hyperthyroidism or intraocular space-occupying lesions.

1. Myopia

can lead to the patient's anterior and posterior diameter becoming longer, that is, the eye axis becomes longer, so exophthalmos will occur, especially in patients with high myopia.

2. Hyperthyroidism

Hyperthyroidism can lead to increased sympathetic nerve activity, increased muscle tension in the upper eyelid, increased volume of external oblique muscle and retrobulbar tissue, thus causing symptoms of exophthalmos. Patients can also be accompanied by reduced blinking times, tears, decreased vision and other manifestations.

3. Intraocular space-occupying lesions

Foreign bodies and tumors appear behind the eyeball, which can squeeze the eyeball, resulting in deviation of eyeball position, generally manifested as unilateral exophthalmos.
