• Stage 0 is a normal optic disc. 
• Stage 1 papilledema is a C-shaped halo of disc edema with preservation of the temporal disc. 
• Stage 2 papilledema is a circumferential halo of edema on the optic disc.  
• Stage 3 papilledema is elevation of the optic disc with partial obscuration of one of more segments of the blood vessels at the disc margin. 
• Stage 4 papilledema is characterized by almost complete obscuration of major blood vessels on the optic disc. 
• Stage 5 papilledema is partial or total obscuration of all blood vessels on the surface of the optic disc.

Each stage is further categorized into AB, ABC or ABCD level
