Cervical spondylosis may cause patients to have blurred vision. Cervical spondylosis causes such symptoms in patients mainly because such lesions cause stimulation of the relevant sympathetic nerve or vertebral artery, and the mechanisms by which such lesions cause such symptoms are mainly as follows: First, when patients have an attack of vertebral artery-type cervical spondylosis, it may be due to osteophytes or soft tissue-related compression around the vertebral artery, which then The diameter of the vertebral artery becomes thinner. In this case, the patient may suffer from insufficient blood supply to the brain, which often leads to dizziness, blackness in front of the eyes, blurred vision and a series of other symptoms. Secondly, when a patient has an attack of sympathetic cervical spondylosis, the stimulation of sympathetic nerves may lead to spasm of the blood vessels related to the vertebral basilar artery, which may also cause a lack of blood supply. On top of this, the patient may also experience easy fatigue, increased secretion or dryness and astringency in one eyelid, and the above-mentioned pathological changes may also cause the patient to have blurred vision.
