The optic disc margins start to blur in the following order in papilledema-
1. Superior
2. Inferior
3. Nasal
4. Temporal
Blurring first occurs where the nerve fibre density is the highest.The optic disc being ovoid in shape, with taperings superiorly and inferiorly, the nerve fibre density is higher there. Hence such a sequence.
That's all!
