Validity of optical coherence tomography angiography in the differential diagnosis of papilledema and pseudopapilledema.

Significant differences were found for flux index in the nasal sector (p = 0.034).

Mean vascular flux index had an AUC of 0.683 (95% CI, 0.518-0.848), with 76.9% sensitivity and 58.8% specificity, with a cut-off of 0.461.

Mean perfusion had an AUC of 0.665 (95% CI 0.492-0.838), with 53.8% sensitivity and 76.5% specificity, with a cut-off of 44.25%.
