Pseudopapilledema is defined as anomalous elevation of one or both optic discs without edema of the retinal nerve fiber layer. Papilledema, on the other hand, is a swelling of the optic disc due to increased intracranial pressure.
True disc edema must be differentiated from pseudopapilledema, where there is an elevated appearance to the nerve head without edema of the nerve fiber layer, as pseudopapilledema has drastically different clinical implications.
What is the difference between papilledema and pseudopapilledema? Pseudopapilledema means false papilledema. In pseudopapilledema, the optic disc looks elevated, but it’s not because of optic nerve swelling.
Papilledema. Bilateral* optic nerve head swelling secondary to increased intracranial pressure (always, by definition) Swollen, blurred margins with splinter hemorrhages and exudates as well as nerve fiber layer edema.
Pseudopapilledema is the term used to descibe the appearce of a swollen optic dics but does not represent true optic nerve edema. This is in contrast to papilledema...
This article reviews how to properly distinguish between pseudopapilledema, such as ONHD, and true papilledema, as well as how to use various diagnostic modalities to make the distinction.
While papilledema is disc edema secondary to increased intracranial pressure, pseudopapilledema is apparent optic disc swelling that simulates some features of papilledema but is secondary to...
Anomalous optic nerve head elevation often mimics papilledema and is therefore known as pseudopapilledema. In this chapter, we review the features that help to distinguish pseudopapilledema from papilledema and we discuss common causes of pseudopapilledema, such as optic nerve head drusen.
Papilledema is defined as pathologic swelling of the optic nerve due to increased intracranial pressure (ICP). Papilledema can signify life-threatening disorders such as brain tumors or meningitis, as well as vision-threatening disorders such as pseudotumor cerebri syndrome [1].
This article aims to discuss optic disc drusen (ODD, or pseudopapilledema) in the context of differentiating it from true papilledema. It is not an easy diagnosis to make, even for the most experienced clinicians, but some of the following salient points may be of assistance. Drusen are a normal clinical finding made up of refractive hyaline ...
