SD-OCT to distinguish papilledema from pseudopapilledema.

CASES REPORT: Two patients presented with headache and bilateral papillary edema. Patient 1 was found to have a papilledema (P) with intracranial pressure of 32cmH2O. Patient 2 was found to have a migraine with a pseudopapilledema (PP) (optic nerve head drusen). SD-OCT was used to image the optic disc, subretinal hyporeflective space (SHS), and alpha-angle (Aα).

DISCUSSION: Optic disc SD-OCT may be useful for differentiating disc morphology in P and PP. The area of the SHS and the Aα were higher in the P patient than in the patient with PP.
