SD-OCT detected papilledema slightly more often than ocular ultrasound.
Ocularultrasound versus SD-OCT in early papilledema differentiation.

Background
Differentiating early papilledema from pseudopapilledema remains a considerable diagnostic challenge in neuro-ophthalmology due the risks surrounding unnecessary neuroimaging or under-treatment of elevated ICP.
Results
SD-OCT (a scan checking eye nerve layers) caught more papilledema cases than ultrasound
SD-OCT sensitivity
86.7%
Ultrasonography sensit
81.7%
More results
Therefore, it is of interest to study of ocular ultrasonography and SD-OCT was carried out in 60 patients with elevation of the optic disc from September 2022 to February 2024.

Conclusion
The two modalities complement each other - SD-OCT provides quantification and allows differentiation whereas ultrasonography can show anatomical biomarkers, together allowing the early detection of intracranial hypertension as well as avoiding invasive investigations in cases of pseudopapilledema.
