“…Spectral domain optical coherence tomography (OCT) is a common method for evaluating the papillary bulge. Optic disc analysis can be widely used in the diagnosis of intracranial hypertension, but OCT images need to be evaluated by an expert examiner (Rosa et al, 2022a). Ultrasound equipment is more common and can be used at the point of care.…”

Background/aim: Patients with elevated intracranial pressure (ICP) tend to have optic disc edema and a thicker optic nerve sheath diameter (ONSD). However, the cut-off value of the optic disc height (ODH) for evaluating elevated ICP is not clear. This study was conducted to evaluate ultrasonic ODH and to investigate the reliability of ODH and ONSD for elevated ICP.Methods: Patients suspected of having increased ICP and who underwent a lumbar puncture were recruited. ODH and ONSD were measured before lumbar puncture. Patients were divided according to elevated and normal ICP. We analyzed the correlations between ODH, ONSD, and ICP. ODH and ONSD cut-off points for the identification of elevated ICP were determined and compared.Results: There were a total of 107 patients recruited for this study, 55 patients with elevated ICP and 52 with normal ICP. Both ODH and ONSD in the elevated ICP group were higher than in the normal group [ODH: median 0.81 (range 0.60–1.06) mm vs. 0.40 [0–0.60] mm, p < 0.001; ONSD: 5.01 ± 0.37 mm vs. 4.20 ± 0.38 mm, p < 0.001]. ICP was positively correlated with ODH (r = 0.613; p < 0.001) and ONSD (r = 0.792; p < 0.001). The cut-off values of ODH and ONSD for evaluating elevated ICP were 0.63 mm and 4.68 mm, respectively, with 73% and 84% sensitivity and 83% and 94% specificity, respectively. ODH combined with ONSD showed the highest value under the receiver operating characteristic curve of 0.965 with a sensitivity of 93% and a specificity of 92%.Conclusion: Ultrasonic ODH combined with ONSD may help monitor elevated ICP non-invasively.

We recently reviewed an article by Torabi et al. [1] in your journal concerning evaluation of optic nerve sheath diameter (ONSD) by ultrasound after moderate traumatic brain injury [1]. The article is noteworthy for its intriguing idea, but we would like to raise several concerns.In the study, the authors utilized a 7.5 MHz linear probe to perform ONSD measurements in axial and coronal sections, most likely using the ultrasound B-scan technique. The B scan is very
