ABSTRACT [Download PDF] [Read Full Text]
Papilledema is due to the increase of intracranial pressure, which leads to the disorder of axoplasmic flow of nerve fibers, optic disc edema and elevation.Pseudopapilledema is mostly due to congenital morphological abnormality of the optic disc, such as optic disc drusen, optic disc tilt and so on.Fundus photography shows unclear optic disc boundaries.It is difficult to distinguish papilledema from pseudopapilledema.Spectral-domain optical coherence tomography (SD-OCT) provides a noninvasive and easy imaging method to obtain high-resolution images that can improve diagnostic accuracy through quantitative indexes such as peripheral nerve fiber layer thickness, optic disc volume and total retinal thickness, or qualitative index such as shape and displacement around the optic disc, retinal fold, and so on.This paper mainly discusses the application value of SD-OCT in differentiating papilledema from pseudopapilledema.
