RESUMEN
Background/aim: We aimed to show the role of determination of optic nerve sheath diameter (ONSD) by bedside ultrasonography in an emergency department in the diagnosis of cerebrovascular disorders and its correlation with the clinical picture. Materials and methods: This prospective cross-sectional study included 55 patients with cerebrovascular disorders and 53 controls. Age, sex, ONSD, comorbid disease status, and multidetector computed tomography results of all subjects and application periods and National Institutes of Health Stroke Scale (NIHSS) scores of the patient group were evaluated. Results: The ONSD of the patient and control groups was determined as a median of 5.7 mm and 3.6 mm, respectively. The ONSD of the patient group was determined to be significantly higher than that of the control group (P < 0.05). A positive relationship was determined between NIHSS scores and ONSD values (P < 0.05). The specificity and sensitivity values were determined as 98.1% and 81.8%, respectively, for a cutoff value of 5 mm and as 100% and 72.7%, respectively, for a cutoff value of 6 mm. Conclusion: This study showed that bedside measurement of ONSD is an easy, cheap, and noninvasive method that can be used to support the diagnosis and evaluation of patients with acute stroke.

BACKGROUND AND OBJECTIVE: To evaluate choroidal thickness using spectral-domain optical coherence tomography (SD-OCT) in patients with obstructive sleep apnea syndrome (OSAS) in comparison to healthy controls. PATIENTS AND METHODS: This observational, comparative study consisted of 35 patients with OSAS and 32 age- and sex-matched controls. The controls did not have systemic or ocular diseases. All study participants underwent complete ophthalmic examination as well as choroidal thickness measurement using a high-speed, high-resolution SD-OCT device. RESULTS: The mean horizontal and vertical choroidal thicknesses, respectively, were 237.84 ± 69.9 µm and 234.97 ± 62.0 µm (P = .654) in patients with OSAS and 244.09 ± 41.2 µm and 241.88 ± 40.9 µm (P = .590) in the healthy controls. The mean choroidal thicknesses were thinner in patients with OSAS, but the difference was not significant (P > .05 for all values). CONCLUSION: No differences in choroidal thickness were found between patients with OSAS and healthy controls.
