Cervicogenic visual dysfunction: an understanding of its pathomechanism

Atypical symptoms of cervical spondylosis include headache, nausea, gastrointestinal discomfort, blurred vision, tinnitus, hypomnesia, and palpitations. Successful treatment of these atypical symptoms has been achieved after conservative non-invasive and surgical spinal treatments, although the role of these interventions in mitigating atypical symptoms of cervical spondylosis is unclear. Our study introduces and elaborates on the visual dysfunction caused by cervical spondylosis. Although there are reports in the literature that spinal manipulation and surgery can improve visual dysfunction, the correlation has remained unclear and controversial. The article reviews the latest research to identify the possible mechanisms of visual dysfunction caused by cervical spine diseases.
