Multimodality evoked potentials and electrically elicited blink reflex in optic neuritis.

Pattern shift visual evoked potentials, brain stem auditory evoked potentials, spinal and scalp recorded somatosensory evoked potentials, and electrically elicited blink reflexes were investigated in 32 patients with isolated optic neuritis. Eleven patients were shown to have one additional lesion in the central nervous system outside the optic nerve. Therefore, cases with optic neuritis of unknown origin should be considered as possible cases of multiple sclerosis.

Acute cerebellar ataxia of childhood and optic neuritis with retrochiasmal involvement.

A case of a 4-year-old white girl affected with unilateral optic neuritis and acute cerebellar ataxia is presented. Visual evoked potentials (VEP) demonstrated prolonged latency of the right optic nerve as well as the left retrochiasmal pathways. This child had complete resolution of the cerebellar ataxia and the optic neuritis with return to normal of her VEP. This case is an example of a disease characterized by a single episode of multifocal involvement of the CNS differing from diffuse encephalomyelitis and multiple sclerosis.

Cell-mediated immunity in acute idiopathic optic neuritis and multiple sclerosis.

Lymphocyte transformation responses to phytohaemagglutinin, measles antigen and tuberculin and the absolute numbers of circulating T and SIg+ cells were determined in 16 patients with acute idiopathic optic neuritis (ON), 42 patients with multiple sclerosis (MS) and 78 healthy controls. Patients with acute ON showed impaired lymphocyte transformation responses in both autologous plasma and AB serum similar in extent to those seen in MS patients in relapse. They were not associated with a reduced total number of circulating T cells.

[On the differential diagnosis of bilateral retrobular optic neuritis (author's transl)].

Two cases of optic nerve neuritis are reported. The first had typical clinical symptoms and the other had an atypical course. In the case of the first patient an astrocytoma was found in the right frontal lobe. The aetiology of the second case was a meningioma of the tuberculum sellae. The clinical findings in our cases are discussed with regard to 58 cases in the literature. In all cases of optic neuritis with typical and atypical course a tumor of the central nervous system must always be taken into consideration.

Acute optic neuritis: a virological study in relation to multiple sclerosis.

Previous ultrastructural examination of peripheral blood lymphocytes revealed the presence of intranuclear filamentous structures in multiple sclerosis (MS) and in some optic neuritis (ON) patients. The present investigation was undertaken in the attempt to correlate the presence of such structures with the etiology of ON and MS and possibly to demonstrate the viral origin of the filaments. Suitable virological and serological techniques were used to detect and isolate infectious agents from peripheral blood samples and body excretions of 12 monosymptomatic ON patients at their first acute att…

[The visually evoked cortical potentials (VECPs) in optic neuritis (author's transl)].

The visually evoked cortical potentials (VECPs) were examined in 22 patients with optic neuritis. 1. In the acute stage, amplitude and latency time of the VECPs are impaired not only on the affected eye, but often also of the fellow eye. 2. A bilateral disturbance of the VECPs often persists in the recovery period, although psychophysical functions, including color vision remain normal. 3. It follows that in cases of unilateral optic neuritis, demyelinations without clinical evidence may occur in the optic nerve of the fellow eye.

Новый биомаркер оптической совместимости для диагностики острого оптического неврата в множестве склерозов.

ЦЕЛЬ: Ценна ли съемка ретроламинарного оптического нерва во время атаки острого оптического неврата в множественных склерозах? МЕТОДЫ: Это перспективное исследование серии наблюдений. Twenty two Пациенты, набранные в клиниках Университета Аль-Азхар и благотворительном центре < < Глазный центр > > Эль-Мустафа, Каир; с октября 2022 по февраль 2024. Пациенты были названы, так как у них развился приступ острого оптического неврита. Полные офтальмологические и неврологические обследования были проведены для всех пациентов внутри 2 недель острого оптического неврата. Изображение перипапо

OBJECTIVES: Is imaging of retrolaminar optic nerve, during attack of acute optic neuritis in multiple sclerosis valuable? METHODS: This is a prospective observational Case series study. Twenty two patients recruited from Al-Azhar University Hospitals and Charity Eye Centre (El-Mustafa Eye Centre, Cairo); from October 2022 to February 2024. The patients were…

Parapapillary choroidal microvasculature in retrobulbar optic neuritis: An optical coherence tomography angiography study.

PURPOSE: To compare superficial and deep vascular characteristics of the optic disc in retrobulbar optic neuritis using optical coherence tomography angiography (OCT-A). METHODS: Nineteen patients with unilateral non-infectious retrobulbar neuritis were included in the study. The contralateral eyes of each patient were served as controls. OCT-A scans of the optic discs were performed in a 4.5 × 4.5 mm rectangular area, while macular OCT-A scans were performed in a 6 × 6 mm rectangular area. Various parameters, including radial peripapillary capillary (RPC) density, peripapillary retinal nerve…

Optical coherence tomography in central nervous system demyelinating diseases related optic neuritis.

AIM: To compare the thickness of the peripapillary retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer (GCIPL) among patients with various forms of optic neuritis (ON) and to identify whether any particular parameters or their thinning pattern can be used to distinguish the type of ON. METHODS: This prospective study was conducted at the Department of Ophthalmology, Faculty of Medicine, Siriraj Hospital, Thailand, between January, 2015 and December, 2016. We enlisted patients over 18 years of age with history of ON and categorized patients into 4 groups: 1) aquaporin 4 an…

Optical coherence tomography is less sensitive than visual evoked potentials in optic neuritis.

OBJECTIVES: Determine the utility of optical coherence tomography (OCT) to detect clinical and subclinical remote optic neuritis (ON), its relationship to clinical characteristics of ON and visual function, and whether the retinal nerve fiber layer (RNFL) thickness functions as a surrogate marker of global disease severity. METHODS: Cross-sectional study of 65 subjects with at least 1 clinical ON episode at least 6 months prior. Measures included clinical characteristics, visual acuity (VA), contrast sensitivity (CS), OCT, and visual evoked potentials (VEP). RESULTS: Ninety-six clinically af…

A 10-Year Single-Center Study of the Clinical Characteristics of Optic Neuritis-Related NMOSD, MS, and Double Seronegative Optic Neuritis, Together with Factors Predicting Visual Outcomes.

The clinical characteristics of three types of optic neuritis (double seronegative optic neuritis; DN-ON, Neuromyelitis optica spectrum disorder-related optic neuritis; NMOSD-ON, and multiple sclerosis-related optic neuritis; MS-ON) were examined in order to identify factors that may affect good visual recovery in Thai patients. The study included patients diagnosed with three types of optic neuritis at Rajavithi Hospital between 2011 and 2020. Visual acuity at the end of 12 months was used as the treatment outcome. Multiple logistic regression analysis was used to evaluate potential predictor…

Optic Nerve Lesion Length at the Acute Phase of Optic Neuritis Is Predictive of Retinal Neuronal Loss.

BACKGROUND AND OBJECTIVES: Acute optic neuritis (ON) is a classical presenting symptom of multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSD), and anti-MOG-associated disorders. The resulting visual impairment is variable and can be severe. Clinicians are in need of predictive biomarkers to optimize the management of acute ON. In this longitudinal study (IRMANO, NCT03651662), we evaluated the ability of optic nerve lesion length measured on MRI at the acute phase of ON to predict retinal neuro-axonal loss and visual impairment at a chronic stage. METHODS: We conducted a l…
