Spinal anesthesia (SA) administered for non-ophthalmic operative surgeries has been associated with ophthalmological disorders in up to 0.2% cases. However, the incidence of medical lawsuits related to these issues amounts to 2-3%, which suggests a probable higher frequency of such violations. This study was conducted to find the nature of ophthalmological disorders during SA and risk factors for their development during non-ophthalmic surgical interventions. Methodology: A prospective cohort non-intervention study was carried out in 150 adult patients undergone nonophthalmic surgical interventions under SA for analysis of state of the visual organs during SA. Results: Ophthalmological disorders after SA were recorded in 6.7% of the patients. These disorders were of a transient nature and were no threat to the development of life-threatening dysfunctions or persistent disablement. They were directly related to the level of systemic arterial pressure. A correlation analysis demonstrated the presence of relation between the reduction in ophthalmotonus and perfusion pressure of the eyes and the administration of 0.5% bupivacaine (R = 0.7, p = 0.01). Conclusion: The results of our study prove that the individuals with prior visual organ disorders are expected to have a relatively high incidence of ophthalmological complications after spinal anesthesia, requiring the individualization of anesthesia regimes.
