A case of retrobulbar neuritis which developed in association with intraarterial continuous infusion cisplatin is presented. [ncbi.nlm.nih.gov]

- Visual Impairment
Some of the symptoms of optic neuritis include: Decreased visual acuity or vision loss Eye pain and impairment of color vision (dyschromatopsia)* *Often, eye pain resolves over a few days as visual loss begins. [chop.edu]
[…] function in patients with ON is usually assessed by visual acuity, and more sensitive measures of visual impairment, such as contrast sensitivity and low-contrast letter acuity. [neurologyindia.com]
The predominant complication of optic neuritis is visual impairment, and in the worst case, blindess. In children, estimates of residual visual impairment range from 25-33% of patients undergoing all treatments. [clinicaladvisor.com]
[…] prognosis, although approximately 20% of eyes remain visually impaired. [meajo.org]
Presentation, assessment and diagnosis Usual presentation This is usually a triad of: Visual impairment (of varying severity, usually developing over a period of hours or days, and may typically be exaggerated by a hot bath or shower). [patient.info]
Workup
A complete workup including cranial imaging, lumbar puncture, and serologic evaluation in patients presenting with acute neuroretinitis is often necessary because treatments are directed toward the underlying pathogen. [lymeneteurope.org]
Evaluation of ON thus requires a brilliant clinical detail, appropriate laboratory workup and imaging. [neurologyindia.com]
Further workup may include CSF studies of cell count, glucose, protein, VDRL and electrophoresis evaluating for oligoclonal bands. [webeye.ophth.uiowa.edu]
If you see no improvement in your condition despite following these tips and remedies, visit your doctor immediately and avail a further diagnostic workup and treatment if necessary. [stylecraze.com]
See Workup for more detail. [emedicine.medscape.com]
Treatment
Prompt treatment with systemic antiviral and steroid improve the visual outcome. [ncbi.nlm.nih.gov]
History also revealed that she had taken anti-tubercular treatment for 6 months for tubercular osteomyelitis in the left knee joint at 10 years of age and was fully cured after complete treatment. [jcor.in]
The Optic Neuritis Treatment Trial (ONTT) supports the administration of intravenous methylprednisolone sodium succinate (Solumedrol, 250 mg. every 6 hours) for three days. [decisionmakerplus.net]

Prognosis The age of symptom onset (younger patients having a more favorable prognosis) and the causative mutation (patients with MT-ND6 mutations showing highest recovery rates) are factors that determine the disease outcome. [orpha.net]

A strong case can be made for "isolated" optic neuritis being a forme fruste of multiple sclerosis, based on similarities between the two in such epidemiologic factors as gender, age, geographic distributions, cerebrospinal fluid changes, histocompatibility [clinicaltrials.gov]

We postulate different pathophysiologic mechanisms of ON in our three patients: compression of optic nerve due to sphenoid mucocele in the first patient; extension of bacterial infection to the optic nerve in the second patient; and invasion of aspergillosis [link.springer.com]

Pathophysiology The pathology of ADON involves demyelination and axonal loss, probably due to an inflammatory process and a delayed hypersensitivity reaction. Recovery is due to remyelination and compensatory neuronal recruitment. [patient.info]
