Clinically, some patients always feel that their vision is blurred. After a long time of ophthalmology examination, they have not found any problems. In addition to eye discomfort, they are often accompanied by dizziness, headache, sore neck, numbness of fingers, and weakness in holding objects. Patients often move from department to department, and finally to the Department of orthopedics, only to find that there is a problem with the cervical spine.
cervical spondylosis often causes eye symptoms such as blurred vision, decreased vision, swollen and painful eyes, photophobia and tears, eye opening fatigue, etc., and even cause visual field narrowing and sharp reduction. These eye diseases caused by cervical spondylosis are called cervical visual impairment.
1. Cervical spondylotic myelopathy is caused by cervical degeneration, hypertrophy of ligamentum flavum, hyperplasia of vertebral margin and facet joints, which causes cervical spinal canal stenosis and oppresses dural sac and spinal cord, resulting in blocked cerebrospinal fluid circulation and poor flow, resulting in increased intracranial pressure, optic papilla edema, and atrophy of optic reticular membrane, thus affecting visual acuity. Other symptoms can be seen in the upper and lower limbs numbness and weakness, holding things easy to fall off, walking instability or difficulty, foot often have the feeling of stepping on cotton.
2. In cervical spondylosis of vertebral artery type, the blood vessels are compressed, twisted or stretched when the vertebral artery passes through the transverse foramen of the cervical spine, resulting in insufficient blood supply to the visual center of the cerebellum and occipital lobe of the brain, resulting in dizziness, blurred vision, Venus in the eye, poor vision and blindness in severe cases. Sometimes it will recover spontaneously after several minutes.
3. Sympathetic cervical spondylosis is due to the stimulation of cervical sympathetic nerve, resulting in dysfunction, eye swelling and pain, fear of light tears, blurred vision, dry eyes, sunken eyeballs, pupil enlargement, etc. Most of them are accompanied by headache, dizziness, cold or red swelling of hands and feet, burning and sweating, as well as unstable blood pressure and abnormal heart. This type rarely appears alone in clinical practice and often coexists with other types.
among them, the incidence of vertebral artery type and sympathetic type is relatively high, often combined, which is the main cause of cervical visual impairment. This kind of patient’s eye examination often can’t find out the obvious reason, the majority presses the cervical vertebra sickness massage treatment, the vision will have the varying degree improvement, the clinical symptom alleviates or disappears.
for cervical disc herniation, bilateral or unilateral vertebral artery nervous system is compressed, resulting in optic nerve edema and ischemic degeneration, which belongs to relatively serious cervical spondylosis. Through dehydration of infusion, nutrition of optic nerve and unique manipulative reduction, symptoms can be significantly relieved in one week.
therefore, the possibility of cervical spondylosis should be considered when the symptoms of the eye, such as vision impairment, eye swelling and pain, and the appearance of Venus in the eyes, are obviously related to the changes of head and neck posture, or these symptoms occur simultaneously or successively with the symptoms of cervical spondylosis, and no obvious cause is found during ophthalmic examination.
