Overview
Classification/Staging
According to the Frisen staging, there are 6 stages of IIH based on the ophthalmoscopic signs:
stage 0
Optic disc is normal but nasal and temporal disc borders are blurred.
stage 1
Increased blurring of the nasal border of optic disc but normal temporal margins.
stage 2
Changes are increase in proportion to stage 1 with elevation of nasal nerve head and temporal border blurring.
stage 3
Changes are increase in proportion to stage 2 with elevation of both nasal and temporal disc border and increased diameter of nerve head.
stage 4
Changes are increase in proportion to stage 3 with nerve head elevation and decreased nerve cup.
stage 5
Increased anterior expansion of nerve head which becomes smooth with dome-shaped appearance.[1]
