Stage 0
Normal disc + blurring of nasal and temporal disc; no obscuration of the vessel + cup is maintained
Stage 1
C shaped blurring of nasal, superior and inferior border
Temporal margin is normal (usually)
Stage 2
Elevation of temporal margin
Stage 3
Elevation of entire disc
Obscuration of retinal vessels at disc margin
Stage 4
Complete obliteration of the cup
Obscuration of retinal vessel on the surface of the disc
Stage 5
Dome shape appearance + all vessels being obscured

i just read ur Lars Frisen Papilledema grading of papilloedema, Its very clear and simple! Very good, God bless you, Best wishes for your future!
ReplyDeleteHey... Yi Bin's here...
ReplyDeleteI think you found this from a website?
http://jnnp.bmj.com/content/45/1/13.full.pdf
This is the link to Lars' original paper... So there is some mistake... For Stage 0, the original sentence is "A normal optic disc, with blurring of the nasal and temporal disc borders by overlying nerve fibre bundles in inverse proportion to the disc diameter (that is little blurring with large discs, and
vice versa)."
In another words, if there is blurring of nasal/temporal border but small, not relatively to disc size, it still consider normal... SO, it doesnt necessary need nasal/temporal blurring for stage 0...
On the other hand, "Blurring of the upper and lower pole
areas is disregarded because of the large normal
variability."... Means if only upper or lower blurring, without significant temporal or nasal involvement, it usually normal variant....
THANKS....
Thanks you Yi Bin.. i will revise the journal again after the end posting exam... thanks for bringing this up.. i really x notice it
