Stage 2

Elevation of temporal margin


Stage 3

  2. Hey... Yi Bin's here...
    I 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....
