Abstract :Abstract Title: Determination of Normal Values of Optic Nerve Sheath Diameter in Turkish Adult Population Using Magnetic Resonance Imaging Introduction: The measurement of optic nerve sheath diameter insert ignore into journalissuearticles values(ONSD); is a reliable tool for the estimation of increased intracranial pressure insert ignore into journalissuearticles values(ICP);. However, it is known that racial changes can occur in human anatomy. In the present study we aimed to determine the normal values of ONSD in Turkish adult population. Methods: This retrospective study involved the collection of data between June 1, 2015 and May 31, 2019, and was conducted on 291 adults known to have no increased cranial/intraocular pressure. The ONSD was measured at 3 mm posterior to the globe on MR images. Results: 291 subjects were enrolled, 63.6% of whom were female. The total median ONSD was 4.40mm insert ignore into journalissuearticles values(4.20 - 4.70);. The median ONSD of the male participants was 4.50mm insert ignore into journalissuearticles values(4.25-4.75);, of the female participants was 4.35mm insert ignore into journalissuearticles values(4.15-4.50); and the difference was statistically significant insert ignore into journalissuearticles values(p = 0.001);. According to statistical analysis, it was found that only the presence of chronic renal failure altered the median of ONSD among the comorbid diseases insert ignore into journalissuearticles values(p = 0.042);. Conclusions: Monitoring and treating increased ICP is crucial. Thanks to an ONSD with a known normal value, recognition and emergency management of this pathology would be easier. We think our study is noteworthy because it is the first study investigating the normal ONSD value in Turkish adult population.
