WebConclusions: This study suggests that ONSD can be a useful tool for the screening of IH, and to decide if invasive methods are needed. However, further study is yet needed, namely in establishing the optimal ONSD cutoff. Descrição: Trabalho Final do Curso de Mestrado Integrado em Medicina, Faculdade de Medicina, Universidade de Lisboa, 2024: URI: Web26 de out. de 2024 · The control group consisted of 22 individuals who applied with other complaints than headaches. ONSD was measured from both eyes before and after the LP. After pre-LP measurements were taken, opening and closing CSF (cerebrospinal fluid) pressure was measured. In the control group, ONSD was measured with optic USG. Web8 de abr. de 2024 · At a cut-off level of 0.22, the sensitivity and specificity were 100% sensitivity and 88.0%. All sonographic ONSD measurements and ratios were significantly correlated with readings calculated from cranial CT images. Conclusion.
