Abstract
We discuss a perplexing case of a 51-year-old female with a history of asthma and morbid obesity, presenting with acute bilateral vision loss of unknown etiology. The patient's clinical course was marked by a constellation of symptoms, including blurry vision, eyeball pain, photophobia, headache, nausea, and dizziness, prompting a multidisciplinary approach for diagnostic evaluation. Despite a comprehensive workup and a temporal artery biopsy ruling out large vessel arteritis, the etiology of vision loss remained elusive until myelin oligodendrocyte glycoprotein (MOG) antibody testing returned positive, implicating myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). High-dose corticosteroid therapy was initiated. However, the patient had worsening visual symptoms and was started on plasmapheresis and subsequent administration of Rituximab to prevent relapses, along with a long-term steroid taper regimen. This case underscores the diagnostic challenge of optic neuritis, particularly in MOGAD. It emphasizes the importance of a thorough evaluation and multidisciplinary collaboration.

Abstract
PURPOSE To report clinical features and follow-up of a case with subretinal hypopyon due to syphilis infection. CASE PRESENTATION We present a case of syphilis admitted with optic neuritis and treated with intravenous pulse steroids without antibiotics. The patient was referred to the uvea clinic in the follow-up because of decreased vision and the onset of multiple retinitis foci. We determined subretinal hypopyon in the left eye and a positive TPHA test. A significant regression was observed in retinitis and hypopyon with antibiotic therapy. CONCLUSION Before starting a steroid treatment, infective etiologies should be considered in patients with optic neuritis. Treating with a high dosage of steroids without antibiotics in syphilis would worsen the clinical features and prognosis.

Neuroophthalmology 2023; 47:136-144. [PMID: 37398505 PMCID: PMC10312022 DOI: 10.1080/01658107.2023.2176891] [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: 10/04/2022] [Revised: 12/12/2022] [Accepted: 01/30/2023] [Indexed: 02/18/2023] Open
Abstract
Multiple sclerosis (MS) is an autoimmune demyelinating disease that often initially presents with optic neuritis (ON). Little is known about the demographic factors and familial histories that may be associated with the development of MS after a diagnosis of ON. We utilised a nationwide database to characterise specific potential drivers of MS following ON as well as analyse barriers to healthcare access and utilisation. The All of Us database was queried for all patients who were diagnosed with ON and for all patients diagnosed with MS after an initial diagnosis of ON. Demographic factors, family histories, and survey data were analysed. Multivariable logistic regression was performed to analyse the potential association between these variables of interest with the development of MS following a diagnosis of ON. Out of 369,297 self-enrolled patients, 1,152 were identified to have a diagnosis of ON, while 152 of these patients were diagnosed with MS after ON. ON patients with a family history of obesity were more likely to develop MS (obesity odd ratio: 2.46; p < .01). Over 60% of racial minority ON patients reported concern about affording healthcare compared with 45% of White ON patients (p < .01). We have identified a possible risk factor of developing MS after an initial diagnosis of ON as well as alarming discrepancies in healthcare access and utilisation for minority patients. These findings bring attention to clinical and socioeconomic risk factors for patients that could enable earlier diagnosis and treatment of MS to improve outcomes, particularly in racial minorities.

Abstract
BACKGROUND Optic neuritis (ON) is the most common optic neuropathy in young adults. MRI is reported to have a high sensitivity for ON. Higher signal strengths of MRI may enhance resolution and lead to better detection of ON. We sought to compare the sensitivity of 3.0 Tesla (T) MRI to that of 1.5 T MRI in detecting acute demyelinating ON. METHODS A retrospective chart review was performed on patients with a clinical diagnosis of optic neuritis at Mayo Clinic Health System from January 2010 to April 2020. Among 1,850 patients identified, 126 patients met the eligibility criteria. Exclusion criteria comprised questionable or alternative diagnosis, diagnosis of ON before the study period, eye examinations performed elsewhere, or absence of fat-saturated head and orbits MRIs performed locally within 30 days of symptom onset. Gadolinium contrast enhancement, T2 hyperintensity, and the radiologic diagnosis of ON were recorded by a neuro-radiologist who was masked to the clinical history and the magnet strength of the MRI. RESULTS Fifty-three patients (42.1%) had 3.0 T MRI, and 73 patients (57.9%) had 1.5 T MRI. Overall, 88.9% (112/126) of patients were determined to have a positive MRI for ON. The radiographic sensitivity for ON was higher in the 3.0 T group compared with the 1.5 T group (98.1% vs 82.2%, respectively [P = 0.004]). The frequency of gadolinium enhancement was found to be greater in the 3 T group compared with the 1.5 T group (98.1% vs 76.7%, respectively [P < 0.001]). T2 hyperintensity was also more often seen in the 3.0 T group compared with the 1.5 T group (88.7% vs 68.5%, respectively [P = 0.01]). CONCLUSIONS 3.0 T MRI is more sensitive than 1.5 T MRI in detecting ON. This finding suggests that 3.0 T MRI is a preferred imaging modality for the confirmation of ON.

Abstract
Antibodies to myelin-oligodendrocyte glycoprotein (anti-MOG-IgG) is a specific biomarker that has been detected in peripheral blood from children with acute multiple encephalomyelitis (ADEM) as well as in adults with aquaporin-4 (AQP4), associated with seronegative opticoneuromyelitis spectrum disease (NMOSD), brainstem encephalitis, longitudinally disseminated transverse myelitis, and optic neuritis. Most experts now consider MOG-IgG-associated disorder (MOG-AD) an independent disease immunopathogenetically distinct from classical multiple sclerosis (MS) and aquaporin-4 (AQP4)-IgG-positive optomyelitis. Isolated, bilateral, and less frequently unilateral OH, with simultaneous or sequential involvement of the eyes, is the most frequent clinical manifestation of MOG-AD. Because of the significant overlap in the clinical and radiological picture, MOG-AD is often misdiagnosed as MS. Timely diagnosis is critical to ensure appropriate treatment. This article describes a clinical case of anti-MOG-IgG encephalomyelitis with late-onset ON initially diagnosed as MS.

Abstract
Background Kikuchi-Fujimoto disease (KFD) is a necrotizing lymphadenitis, and presents fever of unknown origin and cervical lymphadenopathy. Ocular complications are unusual in KFD. Here we report a case of sub internal limiting membrane (ILM) hemorrhage followed by bilateral optic disc hemorrhage in KFD. Case presentation A 16-year-old Japanese man perceived a sudden decrease of right vision 3 days after onset of fever with unknown origin and left cervical lymphadenopathy. At presentation, visual acuity (VA) of right eye was 0.05 in decimal chart (1.30: converted to logarithm of minimum angle of resolution: logMAR). Fundus photograph showed extensive sub-ILM hemorrhage in right eye, and optic disc hemorrhages in both eyes. Fluorescein angiography presented hypo- and hyperfluorescences in optic disc of right eye, and hyperfluorescence in the disc of left eye. To make a definitive diagnosis, cervical lymph node biopsy was performed, and KFD was diagnosed pathologically. Thereafter, fever, headache and the cervical lymphadenopathy disappeared spontaneously. The sub-ILM hemorrhage was drained into the vitreous cavity by neodymium:yttrium-aluminum-garnet laser (Nd: YAG) hyaloidotomy. VA recovered to 1.5 (− 0.18: logMAR VA) in right eye. Conclusion Sub-ILM hemorrhage and optic disc hemorrhage are a KFD-related ocular complication.

Antioxidants (Basel) 2021; 10:antiox10091466. [PMID: 34573098 PMCID: PMC8470542 DOI: 10.3390/antiox10091466] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 09/09/2021] [Accepted: 09/13/2021] [Indexed: 12/19/2022] Open
Abstract
Nonarteritic anterior ischemic optic neuropathy (NAION) is one of the most common acute optic neuropathies that affect the over 55-year-old population. NAION causes the loss of visual function, and it has no safe and effective therapy. Bardoxolone methyl (methyl 2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oate; CDDO-Me; RTA 402) is a semisynthetic triterpenoid with effects against antioxidative stress and inflammation in neurodegeneration and kidney disease that activates the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Moreover, RTA 402 is an FDA-approved compound for the treatment of solid tumors, lymphoid malignancies, melanoma, and chronic kidney disease. Omaveloxolone (RTA 408) is an activator of Nrf2 and an inhibitor of NFκB, possessing antioxidative and anti-inflammatory activities in mitochondrial bioenergetics. RTA 408 is also under clinical investigation for Friedreich ataxia (FA). In this study, a rodent anterior ischemic optic neuropathy (rAION) model induced by photothrombosis was used to examine the therapeutic effects of RTA 402 and RTA 408. Treatment with RTA402 results in antiapoptotic, antioxidative stress, anti-inflammatory, and myelin-preserving effects on retinal ganglion cell (RGC) survival and visual function via regulation of NQO1 and HO-1, reduced IL-6 and Iba1 expression in macrophages, and promoted microglial expression of TGF-β and Ym1 + 2 in the retina and optic nerve. However, these effects were not observed after RTA 408 treatment. Our results provide explicit evidence that RTA 402 modulates the Nrf2 and NFκB signaling pathways to protect RGCs from apoptosis and maintain the visual function in an rAION model. These findings indicate that RTA 402 may a potential therapeutic agent for ischemic optic neuropathy.

Abstract
SIGNIFICANCE Neuroretinitis classically presents with sudden vision loss, disc edema, and macular star formation. However, the classical triad may not always be seen, especially in the case of a pre-existing macular disorder. A thorough clinical examination may still clinch the appropriate diagnosis and prevent unwarranted treatment. PURPOSE This study aimed to report a case of neuroretinitis in an adult woman with pre-existing type 2 macular telangiectasia where the classical pattern of exudation could not be seen. CASE REPORT A 48-year-old woman, type 2 diabetic and hypertensive, presented with sudden painless blurring of vision in the right eye for the past 1 week. Macula in both eyes had loss of transparency and intraretinal crystalline deposits and pigments. The right eye had hyperemic edematous disc with peripapillary retinal hemorrhages and hard exudates. Color vision was grossly abnormal, and a centrocecal scotoma was noted on visual field analysis in the right eye. After a normal systemic evaluation, a diagnosis of right eye neuroretinitis and coexistent bilateral type 2 macular telangiectasia (nonproliferative type) was made. Unilateral painless visual loss, severe dyschromatopsia, and peripapillary hard exudates pointed to the correct diagnosis of neuroretinitis. Observation was advised, and visual acuity improved spontaneously. The disc edema resolved with consequent optic atrophy. CONCLUSIONS Absence of the classical "macular star" appearance does not refute the diagnosis of neuroretinitis when pre-existing maculopathy is present.

Abstract
Early differentiation of neuromyelitis optica spectrum disorder (NMO-SD) from multiple sclerosis (MS) is of paramount importance as NMO-SD (especially relapsing variant) has more severe morbidity than MS. We describe a case of an adolescent girl who presented with repeated episodes of optic neuritis over a period of 4 years with normal brain MRI scans. She was treated initially as relapsing remitting MS, before showing clinical evidence of transverse myelitis (TM), and eventually being diagnosed as NMO-SD. Pulse intravenous methyl prednisolone along with immunosuppressive therapy led to remission of her disease. However, delay in diagnosis as NMO-SD led to visual disability in the left eye. Therefore, in young patients with recurrent optic neuritis and normal brain MRI, it may be prudent to get spinal MRI done to look for TM, even when asymptomatic. In addition, we should keep a low threshold for requesting aquaporin-4 antibody testing in these patients.

Abstract
Introduction: In this study, we attempt to determine the diagnostic performance of shear wave elastography of the optic nerve and adjacent fat tissue in patients with optic neuritis. Methods: The study included a patient group consisting of 72 eyes of 36 patients who were diagnosed with unilateral optic neuritis, and an age-matched control group of 36 eyes of 18 healthy subjects. The patient group consisted of 25 multiple sclerosis patients and 11 recurrent isolated optic neuritis patients. The mean shear wave elastography values of the optic nerves and intraorbital fat tissue adjacent optic nerves were recorded using m/s and kPa as units. ROC curve analysis was performed, and the diagnostic accuracy of shear wave elastography values was determined. Results: The mean shear wave elastography values of the optic nerves with neuritis (2.49 ± 0.41 m/s and 17.56 ± 4.42 kPa) were significantly higher than the values of the contralateral normal optic nerves (1.71 ± 0.32 m/s and 9.02 ± 2.34 kPa) (p = 0.006 and p = 0.004, respectively) in the optic neuritis group. The mean shear wave elastography values of intraorbital fat tissue adjacent optic nerves with neuritis (1.87 ± 0.32 m/s and 9.65 ± 1.12 kPa) were significantly higher than the values of the contralateral normal side (1.47 ± 0.27 m/s and 6.78 ± 1.14 kPa) (p = 0.025 and p = 0.022, respectively) in the optic neuritis group. ROC curve analysis showed a high diagnostic accuracy for determining optic neuritis with shear wave elastography values of the optic nerves (AUC 0.955 [95% CI, 0.933–0.978] in m/s and AUC 0.967 [95% CI, 0.940–0.985] in kPa). Conclusions: Shear wave elastography may be an important alternative diagnostic tool in the diagnosis of optic neuritis.

Abstract
Purpose To compare the structure and function of the retina and the optic nerve in patients with a history of multiple sclerosis (MS)-related demyelinating retrobulbar optic neuritis treated and not treated with systemic steroid therapy. Patients and Methods Thirty-two eyes of 32 MS patients with a past single episode of MS-related demyelinating retrobulbar ON were divided into 2 groups: S(+) consisting of 16 patients treated with intravenous methylprednisolone at a dose of 1g/day for 3 days during the acute stage of ON and S(-) consisting of 16 patients who did not receive any treatment. The following examinations were performed: distance best-corrected visual acuity (DBCVA) (Snellen), slit-lamp examination of the anterior and posterior segment of the eye (90D Volk lens), visual field analysis (Carl Zeiss Humphrey 750 Visual Field Analyzer, 24-2, W-W), macular thickness in the foveal (RT1) and parafoveal region (RT2), as well as peripapillary retinal nerve fiber layer thickness (RNFL) in the temporal, superior, nasal and inferior quadrants (Carl Zeiss Cirrus HD-OCT), assessment of the bioelectrical function of the visual pathway with an emphasis on the optic nerve - pattern visual evoked potentials (PVEP) and of macular ganglion cells and cone photoreceptors - pattern electroretinogram (PERG) (Roland Consult). Results No statistically significant differences were observed between the investigated groups in terms of DBCVA, mean deviation of visual field macular (RT1, RT2) and RNFL thickness in the temporal, superior, nasal and inferior quadrants, as well as of the bioelectrical function (PVEP, PERG). Conclusion The application of steroid therapy should be considered on an individual basis and not as a routine treatment for each patient.

Abstract
Background: Glaucoma is characterized by chronic progressive optic neuropathy with corresponding visual field changes, with or without raised intraocular pressure (IOP). When diagnosing glaucoma or monitoring its progression, the examiner has to rely on the appearance of the optic disc, characteristic retinal nerve fiber layer defects, and corresponding visual field defects. However, similar changes and symptoms may be observed in several other disorders of the optic nerve and retina that may mimic glaucoma, often leading to misdiagnosis. Methods and result: The consequences of misdiagnosis not only result in improper treatment that may impact vision but also would negatively affect the overall health, psychological well-being of the patient, and may have considerable economic implications.Conclusion: The current review describes various conditions that mimic glaucoma and the features that help differentiate these conditions from glaucoma.

Park SH, Park CY, Shin YJ, Jeong KS, Kim NH. Low Contrast Visual Acuity Might Help to Detect Previous Optic Neuritis. Front Neurol 2020; 11:602193.

Abstract
Optic neuritis (ON) has been considered to be an important factor in the diagnosis of multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD), making ON detection increasingly critical for early diagnosis. Furthermore, subclinical ONs presenting no distinct decrease in visual acuity can be missed. Low contrast visual acuity (LC-VA) is known to be able to capture visual loss not seen in conventional high-contrast visual acuity (HC-VA) in MS. Therefore, to increase the sensitivity of ON detection, we investigated the advantage of LC-VA over conventional HC-VA. One hundred and eight patients with demyelinating disease (35 MS, 73 NMOSD) with ON at least 3 months prior and 35 controls underwent neuro-ophthalmic evaluation, including best-corrected conventional high contrast visual acuity (HC-VA) and 2.5% and 1.25% low contrast visual acuity (LC-VA). Receiver operating characteristic (ROC) curve analysis and the area under the curve (AUC) of various visual functions were used to determine the most relevant visual function test for the detection of optic nerve involvement. Additionally, the optimal cutoff point was obtained from the Youden index (J-index) as the points with the best sensitivity-specificity balance. When distinguishing ON from non-ON, the area under the ROC curve (AUC) was highest for the 2.5% LC-VA (0.835, P < 0.001; sensitivity 71.5%, specificity 88.6%), while it was 0.710 (P < 0.001) for the HC-VA and 0.770 (P < 0.001) for the 1.25% LC-VA. In discriminating between controls and ON, the AUC was also highest for the 2.5% LC-VA 0.754 (P < 0.001; sensitivity 71.5%, specificity 78.5%), while it was 0.719 (P < 0.001) for HC-VA and 0.688 (P < 0.001) for 1.25% LC-VA. In eyes with a history of ON (n = 137), the HC-VA and 2.5% LC-VA were abnormal in 64.2 and 71.5%, respectively (P < 0.001), with their combination detecting abnormalities in approximately 85.4% (P < 0.001). The 2.5% LC-VA was superior to HC-VA in detecting ON when distinguishing ON from non-ON or control. The 2.5% LC-VA might be a useful, feasible, and rapid method to detect ON. Furthermore, combining 2.5% LC-VA with conventional HC-VA would be better for detecting optic nerve involvements.

Abstract
BACKGROUND The etiology of the inflammatory ON is multifactorial. Much attention is paid to the inflammatory and immune processes that are likely to contribute to the demyelination and MS development. IL-6, VEGFA, and TIMP-3 genes are thought to be involved in the inflammatory processes and manifestation of CNS demyelination, so we aimed to determine the relationship between VEGFA rs1413711, TIMP-3 rs9621532, IL-6 rs1800796 gene polymorphisms and ON, and ON with MS. MATERIALS AND METHODS Patients with ON, ON with MS, and a random sample of healthy population were enrolled. The genotyping of VEGFA rs1413711, TIMP-3 rs9621532, and IL-6 rs1800796 polymorphisms was carried out using the real-time polymerase chain reaction method. RESULTS T/C and C/C genotypes of VEGFA rs1413711 were associated with about threefold increased odds of developing ON in the dominant and codominant models. Each allele C at VEGFA rs1413711 was associated with 1.7-fold increased odds of ON development. IL-6 rs1800796 allele C was more frequent in the ON with MS group compared to the control: 17.6% vs. 7.5%, respectively (p = .040). No statistically significant associations were found between TIMP-3 rs9621532 and the ON development. CONCLUSION: VEGFA rs1413711 is associated with the ON development.

Abstract
PURPOSE Report a case of concurrent unilateral optic neuritis and central retinal artery occlusion as the presenting signs of syphilis. METHODS A case report of a 22-year-old man with progressive unilateral vision loss. RESULTS With no known previous history of syphilis, genital lesions, or other extraocular manifestations, the patient presented with pain with eye movements and decreased color vision. His vision dramatically worsened after a course of oral steroids. Examination was remarkable for severe right optic disk edema with a macular cherry-red spot and mild posterior uveitis. Magnetic resonance imaging of the orbits with contrast revealed enhancement and enlargement of the distal right optic nerve. Fluorescein angiography demonstrated delayed filling of the right central retinal artery, suggestive of impending central retinal artery occlusion. Syphilis serologies were positive from the serum, and cerebrospinal fluid Venereal Disease Research Laboratory test was reactive, consistent with neurosyphilis. Oral steroids were discontinued and vision improved with 2 weeks of intravenous penicillin. CONCLUSION This unusual case highlights one of the possible initial presentations of syphilis: unilateral optic neuritis and central retinal artery vasculitis with mild posterior uveitis. The worsening of vision after administration of oral steroids also highlights a potential complication of oral steroid use in the absence of a known etiology of vision loss. A thorough history and examination may be helpful in identifying risk factors for infectious causes, including syphilis, and should prompt additional evaluation.

Abstract
Chickenpox may lead to several neurological complications. Optic neuritis is one of the complications which has rarely been described, especially in immunocompetent individuals. We report a case of an 11-year-old immunocompetent girl who presented with sudden onset bilateral vision loss three weeks after varicella eruption. Ophthalmic examination revealed bilateral optic disc edema. Diagnosis of bilateral optic neuritis secondary to varicella was established based upon the preceding medical history, supported with clinical and radiological findings.

Abstract
Demyelination is the most common cause of optic neuritis. Typical optic neuritis needs intravenous steroids followed by tapering dose oral steroids. Atypical optic neuritis entails clinical manifestations that deviate from the classic pattern of features. Atypical ON can have devastating visual results if not treated in a timely fashion. Thus, it is critical that cases of atypical optic neuritis are recognized early to initiate proper treatment and preserve vision. Our case presented as an atypical case of optic neuritis. The patient had painless onset and was not responding to steroids, but presentation in the other eye and systemic administration of antivirals helped in management of this case.

Abstract
A 39-year-old Caucasian man presented with headaches and retro-orbital pain but normal vision. Bilateral optic nerve swelling was found on funduscopy though optic nerve function and computed perimetry were normal and there was no relative afferent pupillary defect. CT venogram and MRI were unremarkable. Cerebrospinal fluid (CSF) opening pressure was normal on lumbar puncture and Treponema pallidum antibodies and T. pallidum particle agglutination test were positive on CSF analysis. He tested negative for HIV. Symptoms rapidly resolved with 2 weeks of intravenous benzylpenicillin. At 1 month follow-up, the right optic nerve swelling had reduced while the left optic nerve swelling had increased; his vision remained unaffected and he was symptom free and continued to have no objective evidence of optic nerve dysfunction.

Abstract
BACKGROUND Optic neuritis (ON) is the most common cause of acute unilateral visual loss in young adults and frequently occurs as the presenting symptom of multiple sclerosis (MS). Recently, we reported activation of peripheral blood CD19 + B-cells in the early stage of ON. In the current study we aimed to identify peripheral blood B-cell molecular markers associated with ON severity and visual outcome. METHODS Expression of B-cell related biomarkers were analysed in patients with the first clinical presentation of acute unilateral ON. Logarithm of the Minimum Angle of Resolution (LogMAR). visual acuity, Optical Coherence Tomography (OCT) imaging, Expanded Disability Status Scale (EDSS) visual score and visual evoked responses were evaluated at onset and visual acuity and EDSS visual score were repeated at 6 months post-ON. RESULTS Thirty patients with acute unilateral ON, 77% female, mean age 33 ± 2.0 years, were enroled in the study. Expression of CD19, CD79A and CD20 B-cell markers significantly correlated with LogMAR visual acuity of the affected eye (r = 0.44, p = 0.01, r = 0.37, p = 0.01 and r = 0.36, p = 0.04, respectively). The marker levels were elevated between 1.5 and 2.2-folds in the group with worse visual acuity (LogMAR>1.0) at onset (CD79A:×1.5, p = 0.013; CD19:×2.25, p = 0.007; CD20:×1.5, p = 0.015) and not correlated with 6 month visual outcome. CONCLUSIONS Among patient with a first event of acute ON, expression of B-cell biomarkers correlated with the severity of the disease. These results could add information on the role of B-cell dysfunction in the early stages of ON.

Abstract
BACKGROUND/OBJECTIVES No guidelines exist for the investigation of treatable causes of chronic optic neuropathy, including sarcoidosis, lupus, and syphilis. The purpose of this study was to determine the diagnostic yield of screening blood work (ACE (Angiotensin Converting Enzyme) for sarcoidosis, Antinuclear Antibodies (ANA) for lupus, CMIA (chemiluminescence microparticle enzyme immunoassay) for syphilis) and contrast-enhanced MRI brain and orbits in atypical unilateral chronic optic neuropathy. SUBJECTS/METHODS Retrospective review from February 2012 to June 2018 at a neuro-ophthalmology practice. Six hundred and eighty-three consecutive charts with optic neuropathy were reviewed. Inclusion criteria were unilateral chronic optic neuropathy and a work-up including contrast-enhanced MRI brain and orbits, CBC, ESR, CRP, ANA, CMIA, and ACE. Exclusion criteria were optic nerve swelling in either eye on initial assessment or an established cause of optic neuropathy. The main outcome measure was diagnostic yield. RESULTS Fifty-seven patients were included. One patient had elevated ACE, seven had positive ANA titers, and three had positive CMIA. Zero patients were diagnosed with sarcoidosis, one patient was diagnosed with lupus-related optic neuropathy, and one patient was diagnosed with syphilitic optic neuropathy. The diagnostic yield of ACE was 0%, ANA was 1.75%, and CMIA was 1.75%. MRI revealed planum sphenoidale meningioma causing compressive optic neuropathy in one patient, giving it a diagnostic yield of 1.82%. CONCLUSION Routine screening blood work (ACE, ANA, CMIA) and MRI brain and orbits for chronic idiopathic unilateral optic neuropathy has low diagnostic yield, especially if clinical suspicion for syphilis, lupus, and sarcoidosis is low. MRI should still be performed in all cases in order to rule out compressive lesions.

Abstract
Misdiagnosis of multiple sclerosis (MS) (the incorrect assignment of a diagnosis of MS) remains a problem in contemporary clinical practice. Studies indicate that misdiagnosed patients are often exposed to prolonged unnecessary health care risks and morbidity. The recently published 2017 revision of the McDonald criteria for the diagnosis of MS provides an opportunity to consider the effect of these revisions on the problem of MS misdiagnosis. The 2017 McDonald criteria include several new recommendations to reduce potential for misdiagnoses. The criteria should be used for the types of patients in which validation studies were performed, specifically those patients who present with typical demyelinating syndromes. MRI lesion characteristics were defined for which McDonald criteria would be expected to perform with accuracy. However, 2017 revisions, which now include assessment for cortical lesions, and the inclusion of symptomatic lesions and positive oligoclonal bands for the fulfillment of diagnostic criteria, may have the potential to lead to misdiagnosis of MS if not applied appropriately. While the 2017 McDonald criteria integrate issues relating to MS misdiagnosis and incorporate specific recommendations for its prevention more prominently than prior criteria, the interpretation of clinical and radiologic assessments upon which these criteria depend will continue to allow misdiagnoses. In patients with atypical clinical presentations, the revised McDonald criteria may not be readily applied. In those situations, further evaluation or monitoring rather than immediate diagnosis of MS is prudent.

Abstract
The etiologies of optic neuropathy include inflammation, ischemia, toxic and metabolic injury, genetic disease, and trauma. There is little controversy over the practice of using steroids in the treatment of optic neuritis--it is well established that intravenous steroid treatment can speed visual recovery but does not alter final visual function. However, there is controversy surrounding the acceptable routes of administration, dosage, and course of treatment. Additionally, the typical patient with optic neuritis is young and otherwise healthy, and thus is likely to tolerate steroids well. In ischemic and traumatic causes of optic neuropathies, the initial injury is not inflammatory, but damage may be compounded by secondary injury due to resultant inflammation and swelling in the confined space of the optic canal. Steroids have been considered as a means of minimizing inflammation and swelling, and thus minimizing the secondary injury that results. However, the use of steroids in traumatic and ischemic optic neuropathies is highly controversial-the evidence for the efficacy of treatment with steroids is insufficient to show that there is significant benefit. Additionally, patients with these conditions are more likely to have comorbidities that make them vulnerable to significant adverse events with the use of steroids. In this article, we attempt to analyze the current state of the literature regarding the use of steroids in the treatment of optic neuropathies, specifically optic neuritis, nonarteritic anterior ischemic optic neuropathy, and traumatic optic neuropathy.

[PMID: 30344260 PMCID: PMC6037261 DOI: 10.3390/medicina54020029] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2018] [Revised: 05/02/2018] [Accepted: 05/04/2018] [Indexed: 11/25/2022]
Abstract
Background and objective: Optic neuritis (ON) is characterized by painful, usually monocular vision loss with decreased visual acuity and defects of the visual field and color vision. The etiology and pathophysiology of ON is not completely clear. It is thought that a matrix metalloproteinase 2 (MMP-2) gene plays an essential role in this autoimmune inflammatory disease. The aim of this study was to determine the relationship between the MMP-2 (-1306 C/T)rs243865 gene polymorphism and ON, and that of ON with multiple sclerosis. Materials and methods: Patients with ON/ON and multiple sclerosis and a control group of healthy individuals were enrolled in this study. The genotyping test of the MMP-2 (-1306 C/T) was carried out using a real-time polymerase chain reaction (PCR) method. Results: Analysis revealed that T allele at the MMP-2 (-1306 C/T) was less frequent in the ON group compared to the control group (14.5% vs. 23.3%, p = 0.031), and was associated with decreased likelihood of ON development (OR = 0.566; 95% CI: 0.333-0.962; p = 0.036). No significant associations were revealed while comparing the subgroups of ON patients with and without multiple sclerosis. Conclusion: The MMP-2 (-1306 C/T) gene polymorphism was found to be associated with ON development.

Abstract
Purpose: Most cases of optic neuritis are idiopathic or are associated with multiple sclerosis. We present a case in which a young female developed post-infectious left optic neuritis following herpes simplex encephalitis (HSE). Case Report: A 24-year-old female presented with a severe headache, fever, and malaise of a one-week duration. Viral encephalitis was diagnosed and treated; intravenous acyclovir (750 mg every 8 h) was administered for 14 days. The patient improved clinically and was prescribed oral valacyclovir (1,000 mg, three times daily) for an additional 3 months as an outpatient. The patient presented again four weeks after the initial admission with left periocular pain and other typical manifestations of optic neuritis. We diagnosed post-infectious left optic neuritis following viral encephalitis. Corticosteroid therapy with 250 mg intravenous methylprednisolone every 6 hours was initiated and the patient showed rapid significant recovery. Conclusion: This case report highlights the patient's clinical course and includes a brief history of the systemic effects of HSE, as well as the pathophysiology, management, and differential diagnosis of post-encephalitic optic neuritis. We suggest that clinicians should routinely perform an ophthalmologic examination during the follow-up visits of such patients.

Abstract
Background The aetiology and pathophysiology of optic neuritis (ON) is not absolutely clear but genetic and inflammatory factors may be also involved in its development. The aim of the present study was to determine the influence of single nucleotide polymorphism (SNP) of CYP4F2 (rs1558139) and serum levels of IL-17A on ON development. Materials and Methods Forty patients with ON and 164 control subjects were evaluated. Patients were divided by gender, also ON patients were divided into two subgroups: ON with and without multiple sclerosis (MS). CYP4F2 rs1558139 was genotyped using real-time PCR. Serum IL-17A levels were measured using ELISA IL-17A kits. Results We found that A/A genotype of CYP4F2 rs1558139 was statistically significantly more frequent in men with ON and MS than in women: 57.1% versus 0%, p = 0.009. Also, allele A was statistically significantly more frequent in men with ON and MS than in women: 71.4% versus 37.5%, p = 0.044. Serum levels of IL-17A were higher in ON group than in control group: (median, IQR): 20.55 pg/ml, 30.66 pg/ml versus 8.97 pg/ml, 6.24 pg/ml, p < 0.001. Conclusion The higher IL-17A levels were found to be associated with ON, while allele A at rs1558139 was associated only with ON with MS in male patients.

Abstract
OBJECTIVE To characterize ocular and neurologic findings, causes, and treatment outcomes of dogs with optic neuritis. PROCEDURE Medical records from dogs with a diagnosis of optic neuritis at North Carolina State University, College of Veterinary Medicine, Veterinary Hospital between 1983 and 2016 were reviewed. RESULTS Ninety-six cases (20 unilateral, 76 bilateral), comprised of 38 males and 58 females with a mean age of 6.1 ± 3.0 years (range 0.5-13), were identified. Seventy-four cases were presented for vision loss, and 42 had other concurrent neurologic abnormalities. Funduscopic findings included optic nerve head elevation (n = 92), peripapillary retinal edema or separation (n = 37), retinal hemorrhage or dilation of retinal vasculature (n = 23), and multiple inflammatory foci in the peripapillary region (n = 13). Retrobulbar optic neuritis was diagnosed in four cases. The final diagnoses included the following: multifocal meningoencephalitis of unknown etiology (MUE, n = 35), isolated optic neuritis (I-ON, n = 42), neoplasia (n = 10), microbial infection (n = 6), orbital inflammation (n = 2), and suspected ivermectin toxicosis (n = 1). Dogs with I-ON were more commonly male, and medium-to-large breed, when compared to dogs with MUE. Follow-up was available in 72 cases, 50 of which remained blind, 10 had partial visual improvement, and 12 were assessed as having normal vision in the affected eye(s). CONCLUSION Optic neuritis was most commonly associated with multifocal MUE or was isolated as the sole neurologic finding, with a similar incidence between the two groups. Findings suggest that a clinical syndrome of isolated optic neuritis, distinct from multifocal MUE, occurs in dogs.

Abstract
Introduction We compared white-black (WB), white-red (WR), and black-red (BR) checkerboard stimulated visual evoked potentials (VEPs) in multiple sclerosis (MS) patients and aimed to evaluate if redcolored VEP is more sensitive than WB VEP for the diagnosis of optic neuritis (ON). Methods Twenty-nine MS patients (21 females [72.4%]) and 35 healthy control subjects (24 females [68.6%]) were included in the study. Neurological and ophthalmological examinations were conducted for all subjects and VEP and optical coherence tomography (OCT) investigations were performed. Results A significant difference was found between MS patients and the control group for WB, WR, BR stimulated VEP P100 latencies and retinal nerve fiber length (RNFL) and ganglion cell complex (GCC) thicknesses, but there was no difference for WB, WR, and rb stimulated VEP amplitude values between the groups. There was no significant pathological difference between the eyes with an ON history in MS and eyes without an ON history in MS and control subjects after WB, WR, and BR stimulation (p=). Conclusions The WB checkerboard stimulated VEP is an ample test for routine use; further studies are necessary regarding the utility of rb stimulated VEP in detecting subclinical ON.

Retinal layer segmentation in multiple sclerosis: a systematic review and meta-analysis. Lancet Neurol 2017; 16:797-812. [PMID: 28920886 DOI: 10.1016/s1474-4422(17)30278-8] [Citation(s) in RCA: 355] [Impact Index Per Article: 50.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2016] [Revised: 03/13/2017] [Accepted: 08/03/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND Structural retinal imaging biomarkers are important for early recognition and monitoring of inflammation and neurodegeneration in multiple sclerosis. With the introduction of spectral domain optical coherence tomography (SD-OCT), supervised automated segmentation of individual retinal layers is possible. We aimed to investigate which retinal layers show atrophy associated with neurodegeneration in multiple sclerosis when measured with SD-OCT. METHODS In this systematic review and meta-analysis, we searched for studies in which SD-OCT was used to look at the retina in people with multiple sclerosis with or without optic neuritis in PubMed, Web of Science, and Google Scholar between Nov 22, 1991, and April 19, 2016. Data were taken from cross-sectional cohorts and from one timepoint from longitudinal studies (at least 3 months after onset in studies of optic neuritis). We classified data on eyes into healthy controls, multiple-sclerosis-associated optic neuritis (MSON), and multiple sclerosis without optic neuritis (MSNON). We assessed thickness of the retinal layers and we rated individual layer segmentation performance by random effects meta-analysis for MSON eyes versus control eyes, MSNON eyes versus control eyes, and MSNON eyes versus MSON eyes. We excluded relevant sources of bias by funnel plots. FINDINGS Of 25 497 records identified, 110 articles were eligible and 40 reported data (in total 5776 eyes from patients with multiple sclerosis [1667 MSON eyes and 4109 MSNON eyes] and 1697 eyes from healthy controls) that met published OCT quality control criteria and were suitable for meta-analysis. Compared with control eyes, the peripapillary retinal nerve fibre layer (RNFL) showed thinning in MSON eyes (mean difference -20·10 μm, 95% CI -22·76 to -17·44; p<0·0001) and in MSNON eyes (-7·41 μm, -8·98 to -5·83; p<0·0001). The macula showed RNFL thinning of -6·18 μm (-8·07 to -4·28; p<0·0001) in MSON eyes and -2·15 μm (-3·15 to -1·15; p<0·0001) in MSNON eyes compared with control eyes. Atrophy of the macular ganglion cell layer and inner plexiform layer (GCIPL) was -16·42 μm (-19·23 to -13·60; p<0·0001) for MSON eyes and -6·31 μm (-7·75 to -4·87; p<0·0001) for MSNON eyes compared with control eyes. A small degree of inner nuclear layer (INL) thickening occurred in MSON eyes compared with control eyes (0·77 μm, 0·25 to 1·28; p=0·003). We found no statistical difference in the thickness of the combined outer nuclear layer and outer plexiform layer when we compared MSNON or MSON eyes with control eyes, but we found a small degree of thickening of the combined layer when we compared MSON eyes with MSNON eyes (1·21 μm, 0·24 to 2·19; p=0·01). INTERPRETATION The largest and most robust differences between the eyes of people with multiple sclerosis and control eyes were found in the peripapillary RNFL and macular GCIPL. Inflammatory disease activity might be captured by the INL. Because of the consistency, robustness, and large effect size, we recommend inclusion of the peripapillary RNFL and macular GCIPL for diagnosis, monitoring, and research. FUNDING None.

Abstract
The ability of novel mitochondrial uncoupler prodrug of 2,4-dinitrophenol (DNP), MP201, to prevent neuronal damage and preserve visual function in an experimental autoimmune encephalomyelitis (EAE) model of optic neuritis was evaluated. Optic nerve inflammation, demyelination, and axonal loss are prominent features of optic neuritis, an inflammatory optic neuropathy often associated with the central nervous system demyelinating disease multiple sclerosis. Currently, optic neuritis is frequently treated with high-dose corticosteroids, but treatment fails to prevent permanent neuronal damage and associated vision changes that occur as optic neuritis resolves, thus suggesting that additional therapies are required. MP201 administered orally, once per day, attenuated visual dysfunction, preserved retinal ganglion cells (RGCs), and reduced RGC axonal loss and demyelination in the optic nerves of EAE mice, with limited effects on inflammation. The prominent mild mitochondrial uncoupling properties of MP201, with slow elimination of DNP, may contribute to the neuroprotective effect by modulating the entire mitochondria's physiology directly. Results suggest that MP201 is a potential novel treatment for optic neuritis.

Abstract
PURPOSE In the present study, we attempted to determine whether ultrasonic elastography (USE) evaluation can be used in a diagnosis of optic neuritis (ON). MATERIALS AND METHODS Thirteen patients who each had one normal eye and one eye with a diagnosis of ON were included in the study. Ultrasonography (US) and USE examinations were performed on the affected and non-affected eyes of all participants. Optic nerve and adjacent fat tissue regions at the same depth were selected, and USE measurements were obtained. The optic nerve diameter was measured in both normal and affected eyes. RESULTS The mean USE values for the optic nerve were 2.58 ± 0.50 m/s in ON eyes and 1.91 ± 0.39 m/s in normal eyes (p = 0.001). The mean USE values for the optic-nerve adjacent tissue were 2.26 ± 0.45 m/s in ON eyes and 1.77 ± 0.22 m/s in normal eyes (p = 0.001). The mean optic-nerve diameter was 3.80 ± 1.09 mm in ON eyes and 3.28 ± 0.98 mm in normal eyes (p = 0.005). CONCLUSIONS USE may be considered an accessible, safe technique for the detection of significant optic-nerve tissue stiffness in ON and may be used an adjunctive tool for confirming this diagnosis.

Abstract
OBJECTIVE The aim of this study was to analyse retinal nerve fibre layer (RNFL), pattern-reversal visual evoked potentials (pVEPs) and relative afferent pupillary defect (RAPD) changes in multiple sclerosis (MS) patients with the consideration of past optic neuritis (ON). METHODS Ophthalmological, neurological, OCT, RNFL and pVEP studies were conducted in 59 MS patients. RAPD tests were performed in 47 of them. Control group consisted of 28 healthy volunteers. RESULTS Abnormal RNFL was found in 59% of cases of eyes with ON and 28% of eyes without ON. In eyes with ON, significantly lower RNFL values were indicated in the temporal and lower quadrants. Elongation of pVEP latency was found in 83% of eyes with ON and 60% of eyes without ON. The average value of pVEP latency was larger and the amplitude was lower in the subgroup of eyes with RNFL at the borderline or below the norm. RAPD was observed only in eyes with ON and with RNFL thinning. No association was found between the RAPD and pVEP parameters. CONCLUSIONS VEPs were more frequently abnormal than RNFL in MS patients. RNFL damage in eyes without ON may indicate neurodegenerations in CNS of MS patients; it can also be the consequence of subclinical ON. SIGNIFICANCE An analysis of RNFL and VEP can be useful for evaluating the optic nerve in MS patients.

Abstract
Aim: To analyze the clinical signs of multiple sclerosis (MS) and show that optic neuritis is one of the first event, which indicates the development of disease. Patients and methods: The study involved 89 cases in which it confirmed MS at the time of the March 2009–2011. Since ophthalmological parameters were analyzed visual acuity (VA), visual field (VF), and retinal nerve fibre layer (RNFL) thickness of peripapillary rim by optic coherent tomography (OCT). Results: Ten(10) patients had ON as the first clinical manifestation of the disease which was statistically significant (X2 =9,7 p=0,01) compared to the manifestation of other clinical signs of disease. In VF, centrocecal scotomas were predominant in 50% of the subjects; the RNFL thinning of the neuroretinal rim was verified in all patients, most often in the upper quadrant. A month after pulse corticosteroid therapy, visual acuity in all patients with ON ranged from 0.6 to 1.0. Conclusion: ON is one of the first MS clinical manifestation. In VF, the most common disturbances are in the centrocecal area. The RNFL thinning was verified in all patients with OCT.

Abstract
Encephalitis has been included in the causes of optic neuritis, but post encephalitic optic neuritis has been rarely reported. Majority of the cases of optic neuritis are either idiopathic or associated with multiple sclerosis, especially in western countries. This is very important in the Asian population where the incidence and prevalence of multiple sclerosis is not as high as in the Western countries. Although post infectious optic neuritis is more common in children, it can also be found in adults and is usually seen one to three weeks after a symptomatic infective prodrome. Here, we present a case of a 48 year-old-male who developed optic neuritis following viral encephalitis. His first presentation was with severe headache of two weeks duration. Viral encephalitis was diagnosed and treated. The patient presented again three weeks later with right eye pain and other features typical of optic neuritis. Corticosteroid therapy facilitated prompt recovery. Optic neuritis is an uncommon manifestation of encephalitis. It is important that both doctors and patients remain aware of post infectious cause of optic neuritis, which would enable a timely diagnosis and treatment of this reversible cause of vision loss.

Preventive effect of vitamin D3 supplementation on conversion of optic neuritis to clinically definite multiple sclerosis: a double blind, randomized, placebo-controlled pilot clinical trial.

Abstract
Multiple sclerosis (MS) presents with optic neuritis (ON) in 20 % of cases and 50 % of ON patients develop MS within 15 years. In this study, we evaluated the preventive effects of vitamin D3 administration on the conversion of ON to MS (primary outcome) and on the MRI lesions (secondary outcome) of ON patients with low serum 25 (OH) D levels. Thirty ON patients (15 in each of 2 groups, aged 20-40 years) with serum 25 (OH) D levels of less than 30 ng/ml were enrolled in a double blind, randomized, parallel-group trial. The treatment group (cases) received 50,000 IU of vitamin D3 weekly for 12 months and the control group (controls) received a placebo weekly for 12 months. Finally, the subsequent relapse rate and changes in MRI plaques were compared between the two groups. Risk reduction was 68.4 % for the primary outcome in the treatment group (relative risk = 0.316, p = 0.007). After 12 months, patients in the treatment group had a significantly lower incidence rate of cortical, juxtacortical, corpus callosal, new T2, new gadolinium-enhancing lesions and black holes. The mean number of total plaques showed a marginally significant decrease in the group receiving vitamin D3 supplementation as compared with the placebo group (p = 0.092). Administration of vitamin D3 supplements to ON patients with low serum vitamin 25 (OH) D levels may delay the onset of a second clinical attack and the subsequent conversion to MS.

Abstract
The aim of this review is to summarize the latest information about optic neuritis, its differential diagnosis and management. Optic Neuritis (ON) is defined as inflammation of the optic nerve, which is mostly idiopathic. However it can be associated with variable causes (demyelinating lesions, autoimmune disorders, infectious and inflammatory conditions). Out of these, multiple sclerosis (MS) is the most common cause of demyelinating ON. ON occurs due to inflammatory processes which lead to activation of T-cells that can cross the blood brain barrier and cause hypersensitivity reaction to neuronal structures. For unknown reasons, ON mostly occurs in adult women and people who live in high latitude. The clinical diagnosis of ON consists of the classic triad of visual loss, periocular pain and dyschromatopsia which requires careful ophthalmic, neurologic and systemic examinations to distinguish between typical and atypical ON. ON in neuromyelitis optica (NMO) is initially misdiagnosed as ON in MS or other conditions such as Anterior Ischemic Optic Neuropathy (AION) and Leber’s disease. Therefore, differential diagnosis is necessary to make a proper treatment plan. According to Optic Neuritis Treatment Trial (ONTT) the first line of treatment is intravenous methylprednisolone with faster recovery and less chance of recurrence of ON and conversion to MS. However oral prednisolone alone is contraindicated due to increased risk of a second episode. Controlled High-Risk Subjects Avonex® Multiple Sclerosis Prevention Study “CHAMPS”, Betaferon in Newly Emerging Multiple Sclerosis for Initial Treatment “BENEFIT” and Early Treatment of MS study “ETOMS” have reported that treatment with interferon β-1a,b results in reduced risk of MS and MRI characteristics of ON. Contrast sensitivity, color vision and visual field are the parameters which remain impaired mostly even after good recovery of visual acuity.
