SUBACUTE RETROBULBAR OPTIC NEUROPATHY
Abstract:
Optic neuritis are neuro-ophtalmic disorders of multiple causes: demyelinating, inflammatory infectious, toxic evolving towards the decrease of visual acuity, recoverable in 75% of patients, central scotoma, impaired chromatic sense on the red/green axis, painful optic neuropathy associated in some patients with residual neurological signs. Optic neuritis affects the optic nerve behind the lamina cribrosa of the papilla until the crossing of the optic nerve in the chiasm. MRI is important in the positive diagnosis of MS. OCT may be useful in the positive diagnosis of optic neuropathy. The risk of developing multiple sclerosis in subacute optic neuritis increases up to 60% at the age of 40. Optic neuritis is: acute in methyl alcohol poisoning, subacute in demyelinating disorders, NRB associated with inflammatory and vasculitis, chronic in tobacco-alcohol intoxication.
