Optical coherence tomography

• In papilledema, the Bruch's membrane is commonly deflected inward, in contrast to eyes with optic neuritis and nonarteritic anterior ischemic optic neuropathy.

• The peripapillery Bruch's membrane angulation is presumed to be caused by elevated pressure in the subarachnoid space, does not correlate with the amount of retinal nerve fiber level swelling, and resolves as papilledema subsides.
