The pathogenesis of optic disc edema (ODE) in raised intracranial pressure is discussed in the light of recent observations on the subject. The findings indicate that ODE is a mechanical phenomenon. The raised cerebrospinal fluid pressure (CSFP) in the sheath of the optic nerve produces axoplasmic flow stasis in the optic nerve head. This results in swelling of the axons, which manifests as early ODE and secondarily produces the well-known optic disc and retinal vascular changes associated with… CONTINUE READING
