[PMID: 37343437 DOI: 10.1016/j.jneuroim.2023.578130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 06/09/2023] [Accepted: 06/13/2023] [Indexed: 06/23/2023]
Abstract
BACKGROUND AND OBJECTIVES To evaluate the factors determining the final clinical phenotype after an initial isolated attack of optic neuritis (ON). ON could be an isolated event or the initial presentation of a chronic neuroimmunological condition. METHODS This was a retrospective analysis of patients presenting to University Hospitals Cleveland Medical Center for an initial, isolated attack of ON. Final clinical phenotypes were idiopathic ON, multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), myelin oligodendrocyte glycoprotein associated disease (MOGAD), or secondary ON (e.g. neurosarcoidosis). Several potential predictors at the time of initial presentation were compared among the different phenotypes to determine early predictors. Categorical variables were compared using Pearson χ2 or Fisher's exact test, and continuous variables were compared using independent t-test. RESULTS Sixty-four patients met criteria (average age 41.3 ± 13.3, 78.1% females). Average time to final diagnosis was 8.3 months, and average follow-up was 47 months. The final phenotypes were MS (22, 34%), idiopathic ON (14, 22%), MOGAD (11, 17%), NMOSD (10, 16%), and secondary ON (7, 11%). White race, unilateral ON, short segment hyperintensity on orbital MRI, classical demyelination on brain MRI, and not requiring PLEX were associated with MS. Older age, poor steroid responsiveness, and requiring PLEX were associated with NMOSD. African American race, bilateral ON, papillitis on fundoscopy, long segment hyperintensity on orbital MRI, and normal brain MRI were associated with MOGAD. Normal or thinned retinal nerve fiber layer on OCT, short segment hyperintensity on orbital MRI, and normal brain MRI were associated with idiopathic ON. CONCLUSION The final clinical phenotype may be predictable at the time of initial ON presentation. This requires a careful evaluation of patient demographics, treatment response, funduscopic findings, OCT, and orbital and brain MRIs. Utilizing early predictors in clinical practice could better inform prognosis and management decisions.

Factors influencing intravenous methylprednisolone pulse therapy in Chinese patients with isolated optic neuritis associated with AQP4 antibody-seropositive neuromyelitis optica. Sci Rep 2021; 11:22229. [PMID: 34782653 PMCID: PMC8593159 DOI: 10.1038/s41598-021-01109-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 09/06/2021] [Indexed: 12/02/2022] Open
Abstract
This study investigated the factors influencing intravenous methylprednisolone pulse (IVMP) therapy for recovering visual acuity in Chinese patients with aquaporin-4 (AQP4) antibody-seropositive neuromyelitis optica-related optic neuritis (NMO-ON). This retrospective case series included 243 affected eyes of 182 patients (36 male, 146 female) diagnosed with NMO-ON in the Neuro-Ophthalmology Clinic of Beijing Tongren Hospital from September 2012 to September 2020. All patients with AQP4-antibody seropositivity had clinical manifestations of acute ON, excluding other diagnoses and received IVMP treatment at 500 mg/day or 1000 mg/day for 3 days. Primary outcome was the extent of improvement in logMAR visual acuity after IVMP treatment. The therapeutic influences of sex, age, baseline visual acuity, therapeutic intervals, and IVMP dose on acute NMO-ON were analysed. Chi-square tests, Mann–Whitney U-tests, Kruskal–Wallis tests, Spearman’s correlation coefficients, and multiple linear regression were used for statistical analysis. Age ranged between 7 and 80 years (median age, 44; interquartile range [IQR], 29–52) years. Among the 243 eyes, the median improvement in logMAR visual acuity was 0.3 (IQR, 0–0.9). Therapeutic efficacy of IVMP was significantly higher in female than in male patients (Z = 2.117, P = 0.034). The treatment effect gradually decreased with increase in age at onset (Rs = 0.157, P = 0.015), and visual improvement was significantly lower in patients aged > 50 years than in those ≤ 50 years (Z = 2.571, P = 0.010). When patients had low visual acuity at onset, improvements were more obvious (rho = − 0.317, P < 0.001); however, final visual acuity was still low (rho = 0.688, P < 0.001). Therapeutic effect was negatively correlated with therapeutic intervals (rho = 0.228, P = 0.001). Dosage of methylprednisolone (1000 mg/day or 500 mg/day) did not significantly influence treatment efficacy (Z = 0.951 P = 0.342). Therefore, IVMP therapy can improve visual acuity in the affected eyes of patients with AQP4 antibody-seropositive NMO-ON with similar effect at 500 mg/day and 1000 mg/day doses. Sex, age at onset, and therapeutic intervals may influence the efficacy of IVMP in patients with NMO-ON.

The effect of optic neuritis treatment trial (ONTT) combined corticosteroid regimen on pattern reversal visual evoked potentials: a prospective follow-up study. BMC Ophthalmol 2021; 21:324. [PMID: 34488685 PMCID: PMC8422770 DOI: 10.1186/s12886-021-02086-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Accepted: 08/27/2021] [Indexed: 11/25/2022] Open
Abstract
Background The combined corticosteroid regimen of the original Optic Neuritis Treatment Trial (ONTT) is used in many centers to treat optic neuritis. Though pattern reversal visual evoked potentials (PRVEPs) are a sensitive, standard measure of visual conduction in optic neuritis, no studies hitherto have investigated the effect of combined ONTT regimen on PRVEPs. We aimed to determine the effect of combined corticosteroid regimen of the ONTT on changes of PRVEPs in patients with first-episode optic neuritis over 3 months post-treatment. Methods This is a prospective, observational study in which 44 patients with optic neuritis were seen pre-treatment (baseline) and follow-up, at 1 month (FU1) and 3 months (FU2). Twenty-nine patients were treated with ONTT combined regimen (ONTT+ Group) while 15 were conservatively managed without corticosteroids (ONTT- Group). The median latency and amplitude values of the P100 PRVEP component and the visual acuity (i.e. LogMAR values) at pre-treatment, FU1 and FU2 were compared in the two groups using Friedman’s rank test and Wilcoxon Signed Ranks test. Results Median P100 latency improved significantly (to the normal range) as early as by 1 month after the commencement of treatment in the ONTT+ Group, and then remained significantly lower than the baseline over next 2 months. In the ONTT- Group, the median P100 latency improved more slowly over the two follow up assessments and reached the normal range by 3 months. Median visual acuity values also improved significantly at 1 and 3 months after the commencement of treatment in the ONTT+ Group but not in the ONTT- Group. Conclusion ONTT combined corticosteroid regimen improves conduction in the visual pathways of patients with first-episode optic neuritis earlier than does conservative management. We provide electrodiagnostic evidence that combined ONTT regimen–compared with conservative management–results in early remission of visual conduction abnormalities in first-episode optic neuritis.

Abstract
Vision loss can occur due to a variety of etiologies along the primary visual pathway. Understanding the anatomic organization of the visual pathway, which spans the globe to the occipital cortex, can help tailor neuroimaging to identify the cause of visual dysfunction. In this review, relevant anatomy and optimization of computed tomography and magnetic resonance imaging techniques will be described. This will be followed by a discussion of imaging findings related to pathologies at each functional anatomic level.

Abstract
Purpose To improve the treatment efficiency of optic nerve diseases by delivering therapeutic materials to the optic nerve directly. Methods We tried to optimize liposomal composition to deliver a payload to the optic nerve efficiently when it is injected intravitreally. After loading dexamethasone into this liposome, we tested the therapeutic effect of liposomes in this treatment using a murine model of ischemic optic neuropathy. Results Our optimized liposome can deliver its payload to the optic nerve more efficiently than other tested compositions. Moreover, dexamethasone-loaded liposomes had a significant therapeutic effect in a murine model of ischemic optic neuropathy. Conclusions Here, we demonstrate the optimal composition of liposomes that could efficiently deliver intravitreally injected exogenous compounds to the optic nerve. We expect that the intravitreal injection of liposomes with the suggested composition would improve the delivery efficacy of therapeutic compounds to the optic nerve.

Abstract
Many previous studies have demonstrated that the blindness patients have has functional and anatomical abnormalities in the visual and other vision-related cortex. However, changes in the brain function in late monocular blindness (MB) at rest are largely unknown. In this study, we investigated the underlying regional homogeneity (ReHo) of brain-activity abnormalities in patients with late MB and their relationship with clinical features. A total of 32 patients with MB (25 male and seven female) and 32 healthy controls (HCs) (25 male and seven female) closely matched in age, sex, and education underwent resting-state functional MRI scans. The ReHo method was used to assess local features of spontaneous brain activities. Patients with MB were distinguishable from HCs using the receiver operating characteristic curve. The relationship between the mean ReHo in brain regions and the behavioral performance was calculated using correlation analysis. Compared with HCs, patients with MB showed significantly decreased ReHo values in the right rectal gyrus, right cuneus, right anterior cingulate, and right lateral occipital cortex and increased ReHo values in the right inferior temporal gyrus, right frontal middle orbital, left posterior cingulate/precuneus, and left middle frontal gyrus. However, there was no significant relationship between the different mean ReHo values in the brain regions and the clinical features. Late MB involves abnormalities of the visual cortex and other vision-related brain regions, which may reflect brain dysfunction in these regions.

Abstract
Optic neuritis is a common inflammatory disease of the optic nerve. And the cerebral spinal fluid (CSF) in the subarachnoid space of optic nerve is thought to be homogeneous as in spine. We report a case of optic neuritis, some unexpected opaque fluid observed to flow out from the optic canal during the optic canal decompression surgery when the CSF in spine is normal. One day after the surgery, the visual acuity of the patient improved dramatically to 0.4 from 0.05. This report highlights the possible restrictive pathological changes of the CSF in the optic nerve of acute optic neuritis, which may be the reason of the dysfunction of the optic nerve.

Abstract
The use of magnetic resonance imaging (MRI) for the diagnosis of emergent life-threatening neurologic conditions and what are considered "do not miss" pathologies has dramatically increased over the past 10 years due to its increasing importance in the emergency department. Although computed tomography is likely to remain the more significantly used imaging modality due to lower cost and faster speeds, continuing technological advances in MRI have made its use more mainstream. Knowledge of specific clinical signs and symptoms as well as the technical limitations of MRI should help to guide emergency department clinicians with both the recognition and the appropriate use of emergent MRI.

Abstract
Purpose Demyelinizing neurological disease is a rare complication after treatment with tumor necrosis factor (TNF)α antagonists. We report on a case of multiple sclerosis after TNFα antagonist treatment and discuss its differential diagnosis. Methods This is an observational case study. Results A 48-year-old male was referred to Ophthalmology in January 2015 for an absolute scotoma in the superior quadrant of the visual field in his right eye. Visual acuity was 20/50 in the right eye and 20/20 in the left. Fundus examination was unremarkable bilaterally. Spectral domain optical coherence tomography revealed a normal macular retina structure. Visual field examination revealed a superior hemianopsia in the right eye. Head magnetic resonance imaging showed findings compatible with optic neuritis. The visual evoked potentials confirmed the presence of optic neuritis. The patient had been under therapy with adalimumab since January 2014, for Crohn's disease. Suspension of adalimumab was recommended, and it was substituted with tapered deltacortene, from 1 mg/kg/day. After 1 month, the scotoma was resolved completely. Conclusions TNFα antagonists can provide benefit to patients with inflammatory autoimmune diseases. However, they can also be associated with severe adverse effects. Therefore, adequate attention should be paid to neurological abnormalities in patients treated with TNFα antagonists.

Abstract
We present the results from a patient with relapsing optic neuropathy treated within the Stem Cell Ophthalmology Treatment Study (SCOTS). SCOTS is an Institutional Review Board approved clinical trial and has become the largest ophthalmology stem cell study registered at the National Institutes of Health to date (www.clinicaltrials.gov Identifier NCT 01920867). SCOTS utilizes autologous bone marrow-derived stem cells (BMSCs) for treatment of retinal and optic nerve diseases. Pre-treatment and post-treatment comprehensive eye exams of a 54 year old female patient were performed both at the Florida Study Center, USA and at The Eye Center of Columbus, USA. As a consequence of a relapsing optic neuritis, the patient's previously normal visual acuity decreased to between 20/350 and 20/400 in the right eye and to 20/70 in the left eye. Significant visual field loss developed bilaterally. The patient underwent a right eye vitrectomy with injection of BMSCs into the optic nerve of the right eyeand retrobulbar, subtenon and intravitreal injection of BMSCs in the left eye. At 15 months after SCOTS treatment, the patient's visual acuity had improved to 20/150 in the right eye and 20/20 in the left eye. Bilateral visual fields improved markedly. Both macular thickness and fast retinal nerve fiber layer thickness were maximally improved at 3 and 6 months after SCOTS treatment. The patient also reduced her mycophenylate dose from 1,500 mg per day to 500 mg per day and required no steroid pulse therapy during the 15-month follow up.

Abstract
BACKGROUND A relationship between optic neuritis and multiple sclerosis has previously been reported in non-Asian adults. We extended the investigation to Korean children. OBJECTIVES We compared the clinical features, laboratory findings, and visual outcomes of optic neuritis between prepubertal children and postpubertal adolescents and evaluated the conversion rate of optic neuritis to multiple sclerosis in Korean children. METHODS We conducted a retrospective analysis of children less than 18 years of age presenting with optic neuritis at Pusan National University Hospital between January 2002 and December 2013. Outcomes and clinical, ophthalmologic, magnetic resonance imaging, and laboratory findings were reviewed. RESULTS Twenty-six children (male:female, 1:1.2) were included. Follow-up duration was 16.3 ± 27.5 months in the prepubertal children (≤10 years, n = 13) and 8.2 ± 9.2 months in postpubertal adolescent (>10 years, n = 13) (P = 0.32). There was no significant difference between the prepubertal group and postpubertal group in clinical, ophthalmologic, magnetic resonance imaging, or laboratory findings. Of two patients (7.7%) with abnormal brain magnetic resonance images, one developed multiple sclerosis and the other developed acute disseminated encephalomyelitis. Of three patients (11.5%) with relapsing optic neuritis, two developed systemic lupus erythematosus and one developed multiple sclerosis. CONCLUSION The risk of developing multiple sclerosis after pediatric optic neuritis was low (7.7%). Abnormal brain magnetic resonance imaging and relapsing optic neuritis should alert the clinician to systemic or neurological disorders.

Abstract
BACKGROUND Optic neuritis is an important pediatric disorder causing visual impairment. Because of the absence of pediatric-specific studies, data extrapolated from the adult-based optic neuritis treatment trial are used to guide management of pediatric patients. Recent literature promotes a prolonged course of oral steroids to prevent relapses. However, there are no published data to support this view. Patients who were recently treated in our hospital received a longer course of steroids, relative to those treated several years ago. We hypothesized that a longer course of steroids results in fewer relapses and better final visual acuity. METHODS A retrospective analysis of 26 consecutive patients (age 4.5-19 years) treated for optic neuritis within the past 10 years was conducted. Patients received either a short course (2 weeks) or a prolonged course (more than 2 weeks) of steroids. Some patients were not treated. Mean follow-up was 70 weeks (3 weeks-10 years). Comparisons were made among the groups receiving 2 weeks of steroid treatment (16 of 26 patients) and greater than 2 weeks of steroid treatment (seven of 26 patients) to evaluate relapse rate, eventual visual acuity, and reported side effects. RESULTS There were no significant differences in the relapse rates, reported side effects, and final visual acuity in the two treatment groups. CONCLUSIONS In this cohort, a prolonged course of steroids was not associated with reduced relapse rate, increased side effects, or improved visual outcome. This cohort was small, but the results do not identify any reason to deviate from the common approach of optic neuritis treatment, which is 2 weeks of steroids.

Abstract
Optic neuritis is an inflammation of the optic nerve and may be related to different systemic conditions. The clinical presentation of this pathology usually includes sudden loss of visual acuity (VA) which may be unilateral or bilateral, visual field restriction, pain with eye movements, dyschromatopsia, a relative afferent pupillary defect and optic disk swelling. Optic neuritis in children has specific clinical features and a better prognosis than in adulthood. Although usually appears an underlying viral disease, the main concern for practitioners is the relationship of optic neuritis with multiple sclerosis. In addition to the classical techniques as magnetic resonance imaging (MRI), current tendencies of diagnosis for eye practitioners include new imaging devices as optical coherence tomography (OCT), useful to show a thinning of the retinal fibers layer (RFL) after the inflammatory episode. Regarding the management of these patients, short-term intravenous steroid dosages seem to be the best option to treat acute attacks characterized by a very poor bilateral VA.

Abstract
Acute optic neuritis is the most common optic neuropathy affecting young adults. Exciting developments have occurred over the past decade in understanding of optic neuritis pathophysiology, and these developments have been translated into treatment trials. In its typical form, optic neuritis presents as an inflammatory demyelinating disorder of the optic nerve, which can be associated with multiple sclerosis. Atypical forms of optic neuritis can occur, either in association with other inflammatory disorders or in isolation. Differential diagnosis includes various optic nerve and retinal disorders. Diagnostic investigations include MRI, visual evoked potentials, and CSF examination. Optical coherence tomography can show retinal axonal loss, which correlates with measures of persistent visual dysfunction. Treatment of typical forms with high-dose corticosteroids shortens the period of acute visual dysfunction but does not affect the final visual outcome. Atypical forms can necessitate prolonged immunosuppressive regimens. Optical coherence tomography and visual evoked potential measures are suitable for detection of neuroaxonal loss and myelin repair after optic neuritis. Clinical trials are underway to identify potential neuroprotective or remyelinating treatments for acutely symptomatic inflammatory demyelinating CNS lesions.

Abstract
PURPOSE OF REVIEW This review discusses evaluation and treatment of neuro-ophthalmic disorders in the pregnant patient. RECENT FINDINGS Any neuro-ophthalmic abnormality seen in nonpregnant women can be seen in pregnant women. Pregnancy-specific complications (preeclampsia and eclampsia) cause visual symptoms and can affect the entire visual axis. SUMMARY Appropriate evaluation and examination is important to preserve the health and vision of the mother and prevent complications in the fetus. Evaluation should proceed in the same way for a pregnant patient as it would for a nonpregnant patient, with few exceptions. Treatment decisions may be influenced by stage of pregnancy.
