Whitish bands composed of medullated nerve fibres radiating out from the optic disc are of no pathological significance and must not be confused with papilloedema.

在视盘周围呈放，由有髓鞘神经纤维所组成白色条物，是无病意义，不要与乳头水相混淆。

Seven of 15 patients had mild papilloedema, five had fully papilloedema, and the optic discs in other three cases were normal.

5例完全视乳头水,4例(5只眼)有视乳头边缘或附近视网膜前小片出血。
