Optic neuritis (ON) is an inflammatory disorder of the opticnerve. Most cases are idiopathic or associated with MS. ON canbe associated with a variety of systemic or ocular disordersand is the most common acute optic neuropathy in adults youngerthan 46 years. Among high-risk populations for MS, the incidenceof ON is about 3 per 100,000 population per year, whereas inother areas the incidence is about 1 per 100,000 populationper year.1-13
Acute ON often presents as an isolated clinical event withoutcontributory systemic abnormalities (monosymptomatic ON). Clinicalfeatures include periocular pain, abnormal visual acuity andfields, reduced color vision, a relative afferent pupillarydefect, and abnormal visual evoked potentials. The fundus mayappear normal or demonstrate edema of the optic nerve head (papillitis).12-18MRI white matter abnormalities identical to those seen in MSare found in 50 to 70% of monosymptomatic ON cases.19-22 Thevisual deficit of ON may worsen over 1 to 2 weeks and usuallybegins improving over the next month. Lack of improvement invisual function by 30 days is unusual.23 However, most patientshave some residual visual function deficit, even if visual acuityimproves to 20/20.1-18 Differential diagnosis includes compressive,ischemic, hereditary, toxic, or other inflammatory optic neuropathies(e.g., sarcoid). These conditions usually do not exhibit thesame clinical pattern (table 1) or rate of recovery as monosymptomaticON.1-13
Table 1. Features of acute demyelinating monosymptomatic optic neuritis
Treatment of monosymptomatic ON has included oral, retrobulbar,and IV steroids, immunoglobulin, and acupuncture.23-77 Monosymptomaticacute ON is not rare and because the usefulness of oral prednisonein this disorder has recently been questioned,23,78-82 thispractice parameter was developed to provide recommendationsregarding the management of this common neurologic problem.
A literature search was conducted using Medline and Healthstarfrom 1966 to July 1, 1999. ON was cross-referenced with treatmentand therapy. Citations earlier than 1966 were searched by cross-referencingtechniques and an Index Medicus hand search. A total of 582different citations dealing with ON and some aspect of therapywere identified and reviewed. Only literature published in well-disseminatedjournals dealing specifically with MS-related or idiopathicON involving at least three patients was retained. Both retrospectiveand prospective data were reviewed. Citations were excludedwhen they simply described a small number of individual casereports or reviewed "ON" due to diseases such as sarcoid, lupus,anterior ischemic optic neuropathy, trauma, hereditary opticneuropathy, optic nerve compression, or other unrelated opticneuropathy.
Several studies were identified, the largest of which was theNational Eye Institutesponsored Optic Neuritis TreatmentTrial (ONTT).11,12,23,30-33,39,56-5961-77,83-85 The ONTT enrolled457 patients with acute ON, age 18 to 46 years, and followedthem for 6 months or longer.23 The study subsequently completed5-year follow-up on a cohort of 388 ON patients with no historyof MS.83,85
ONTT patients were randomized into three treatment groups within8 days of symptoms onset: 1) oral prednisone alone (1 mg/kgevery day) for 14 days (oral treatment group); 2) IV methylprednisolonesodium succinate 250 mg four times daily (1000 mg/day) for 3days in hospital, followed by oral prednisone (1 mg/kg everyday) for 11 days as outpatient (IV treatment group or IVMP);or 3) oral placebo for 14 days (placebo group). The prednisonearm of the study was double-masked, whereas the IVMP arm wassingle-masked. The use of a placebo IV group was not includedbecause study organizers could not justify, ethically or financially,hospitalizing patients for 3 days of sham IV therapy.65,84
The study was designed to determine speed and level of recoveryand complications of therapy. Visual acuity, visual fields,contrast sensitivity, and color vision were measured at studyentry and at seven follow-up visits during the first 6 months,at 1 year, and then annually for 5 years. MRI was performedin nearly all patients at study entry. Lumbar puncture was optionaland performed in 133 of 457 (29.1%) of the cohort.65,84 Twoof 457 patients were eventually discovered to have compressiveON.
Oral prednisone at 1 mg/kg/day (previously the most common methodof treating ON) failed to demonstrate any statistically significantimprovement in the speed or degree of visual recovery comparedto placebo.23 The IV treatment group, by contrast, had significantlyfaster visual recovery than placebo over the first 30 days (p= 0.02 and p = 0.0001 for the respective primary outcomes) but,after 6 months, there were no significant differences in visualacuity in the three treatment groups.23 After 12 months of follow-up,visual acuity in the study eye was better than 20/20 in 69%and 20/200 or worse in only 3%.86 The only predictor of a poorvisual outcome was poor visual acuity at study entry. Of 160eyes starting at 20/200 or worse, only 8 (5%) were still 20/200or worse at 6 months.12,23,67
Recurrent ON was greater in the group treated with oral prednisonealone than in the other two groups.23,61,62 Also by year 2,30% of patients in the oral treatment group experienced at leastone new attack of ON in either eye compared to 16% in the placebogroup and 13% in the IV treatment group.23,71,75 This disparityamong treatment groups continued throughout the 5-year follow-upperiod (41% recurrences in the prednisone treatment group and25% in the IV and placebo groups; p = 0.004). Also, the ONTTnoted that IVMP was associated with reduced risk of developingclinically definite MS in patients with an abnormal brain MRIat study entry and followed for 2 years compared to the twoother treatment groups.71,83,87 These relationships betweentreatment and both recurrent ON and MS remain unexplained andcontroversial.78-82,88 Herishanu et al.40 suggested that bothrecurrent ON and ON conversion to MS were greater followingthe use of IVMP compared to oral prednisone. This study, however,retrospectively evaluated a total of only 26 nonrandomized patientsreceiving no therapy, oral prednisone or IVMP, and, therefore,provides essentially Class III evidence of any such associations.
In the ONTT the therapeutic effect of the IVMP was no longersignificant by the third year of follow-up (table 3).75,83 Amongpatients with a normal MRI, the 2-year rate of MS was so lowthat a benefit from IV treatment could not be established (seetable 3). 83 The IV treatment arm of the ONTT was single masked.71,89Patients or neurologists, using a detailed and standardizedprotocol months or years after therapy, are unlikely to havebeen biased in reporting attacks of demyelination in the IVMPgroup or in any of the other treatment groups.76 All patientforms were reviewed without knowledge of the treatment arm bya neurologist experienced in MS.76
Table 3. Cumulative probability of patients with clinically definite MS after specific time intervals by treatment group83
Four other Class I and three other Class II corticosteroid treatmenttrials in ON that were relevant to this practice parameter wereidentified (see table 2).30-33,39,56-59 All were prospective,randomized, and placebo-controlled studies, although employingsample sizes considerably smaller than the ONTT. Thus, thesestudies lack the statistical power to exclude a therapeuticbenefit to steroid treatment.90 Several of these Class I studiesreport positive results. For example, Rawson et al. found thatthe speed of recovery in visual acuity was faster in patientsreceiving ACTH (40 units IM daily for 30 days; p < 0.01)compared to placebo over the first 30 days, although by 12 monthsthere was no significant difference between groups.30,31 Bowdenet al.32 similarly demonstrated that visual acuity was the sameat 12 months in patients treated with either ACTH (40 unitsIM daily for 30 days) or placebo. Kapoor et al. showed no effectof IVMP (1000 mg/d x 3 days) compared to placebo on the visualoutcome at 6 months in 66 individuals with ON lesions involvingthe optic canal.56 Sellebjerg et al. studied 60 patients59 usingeither 500 mg of oral methylprednisolone daily for 5 days witha 10-day taper or placebo. They reported that there was an increasedspeed of visual recovery in the treated group (p = 0.008) butno long-term benefit compared to placebo. There was no increasein recurrence of ON at 1 year using oral methylprednisolone;however, they noted that the number of patients was too lowto rule out an effect on subsequent disease activity.59
Three Class II studies were noted. Gould et al. found that ONtreated with a single dose of retrobulbar triamcinolone (40mg) was associated with nonsignificant increase in the speedof visual recovery but resulted in no benefit compared to placeboat 12 months.33 In 1999, Wakakura et al. evaluated 66 patientswith optic neuritis treated with either 1000 mg IVMP for 3 daysor mecobalamin (500 mg/day) and found that IVMP improved thespeed of visual recovery in the first several weeks (p <0.05) but that visual function at 12 weeks and 1 year did notdiffer between the two groups.13,58 Another oral methylprednisolonestudy has also been reported. The Tübingen study tested50 patients,39,57 14 of whom were treated patients with 100mg of oral methylprednisolone for 3 days, subsequently taperingthe dose by 20 mg every 3 days thereafter. At 4 weeks the treatedgroup had a 61% better visual outcome (nearly normal function)compared to placebo (thiamine), although this was not statisticallysignificant. By 12 months, however, no such difference was apparent.
Thirteen Class III studies were also identified (see table 2).These included reports from the early 1950s dealing with glucocorticoidtreatment of ON.24,27 All of these studies had serious methodologicflaws related to very low patient numbers,90 retrospective analysis,no randomization, or lack of placebo control.24,27-29,34,35,40-42,44,53-55In a 1988 publication, Spoor and Rockwell showed rapid recoveryof vision (some within 24 hours) in 12 patients given 1 to 2g of IVMP. This study was neither randomized nor placebo-controlled.41A study by Alejandro et al. in 1994 looked at eight patientsgiven IVMP versus eight patients treated with oral prednisoneand found no difference between groups.55 Other studies arelisted in table 2.
There are also several studies reviewing the prognostic valueof MRI and CSF in determining the relative risk of developingMS after ON.20,60,83,91 However, an in-depth analysis of thatwork is beyond the scope of this practice parameter.
Definitions for the strength of recommendations were based onthe following criteria:
Standard: A principle for patient management that reflects ahigh degree of clinical certainty (usually this requires ClassI evidence that directly addresses the clinical question, oroverwhelming Class II evidence when circumstances preclude randomizedclinical trials).
Guideline: A recommendation for patient management that reflectsmoderate clinical certainty (usually this requires Class IIevidence or a strong consensus of Class III evidence.
Practice Option: A strategy for patient management for whichthe clinical utility is uncertain (inconclusive or conflictingevidence or opinion).
Practice Advisory: A practice recommendation for emerging and/ornewly approved therapies or technologies based on evidence fromat least one Class I study. The evidence may demonstrate onlya modest statistical effect or limited (partial) clinical response,or significant costbenefit questions may exist. Substantial(or potential) disagreement among practitioners or between payersand practitioners may exist.
Acute monosymptomatic ON recommendations.
Oral prednisone in doses of 1 mg/kg/day has no demonstratedefficacy in the recovery of visual function in acute monosymptomaticON, and therefore is of no proven value in treating this disorder.Standard
Higher dose oral or parenteral methylprednisolone or ACTH mayhasten the speed and degree of recovery of visual function inpersons with acute monosymptomatic ON. There is, however, noevidence of long-term benefit for visual function. The decisionto use these medications to speed recovery but not to improveultimate visual outcome should therefore be based on other non-evidencebasedfactors such as quality of life, risk to the patient, visualfunction in the fellow eye, or other factors that the cliniciandeems appropriate. Guideline
Several management issues still lack evidence for specific recommendations:1) whether corticosteroid treatment is beneficial in patientswhose symptom duration is longer than 8 days; 2) whether largerdoses of corticosteroids are more effective than lower doses;3) what the optimal corticosteroid regimen is; 4) whether theobserved increased ON recurrence rate associated with oral prednisoneis also observed in MS attacks; and 5) whether high-dose methylprednisolonegiven periodically will improve the prognosis for patients withMS.
