Neuroophthalmology

BACKGROUND: Neurodegeneration in multiple sclerosis (MS) affects the visual system but dynamics and pathomechanisms over several years especially in primary progressive MS (PPMS) are not fully understood. METHODS: We assessed longitudinal changes in visual function, retinal neurodegeneration using optical coherence tomography, MRI and serum NfL (sNfL) levels in a prospective PPMS cohort and matched healthy controls. We investigated the changes over time, correlations between outcomes and with loss of visual function...

Optical coherence tomography (OCT) has become the most important innovation in ophthalmology over the last 30 years and is used routinely, especially in the diagnosis of retinal and glaucomatous diseases. It is fast, non-invasive and reproducible. Since the procedures can offer such a high resolution that the individual retinal layers can be visualised and segmented, this examination technique has also found its way into neuroophthalmology. Especially the peripapillary nerve fibre layer (RNFL) and the ganglion cell layer (GCL) provide valuable diagnostic and prognostic information in cases of visual pathway disease and morphologically unexplained visual disorders...

Neuromyelitis optica spectrum disorders (NMOSD) comprise a group of autoimmune inflammatory demyelinating diseases of the central nervous system that manifest as optic neuritis and transverse myelitis. Its manifestation in the form of optic neuritis makes early diagnosis difficult because neuroimaging of the spinal cord is not a part of the routine examination algorithm for such patients. This article presents the results of a comprehensive ophthalmological examination of 4 patients (8 eyes) diagnosed with NMSOD...

Background : Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is commonly associated with early-onset stroke, migraine and vascular dementia. However, optic nerve involvement has been previously recognised. Results : We report a case of a 21-year-old female presenting with right inferior temporal scotoma, dyschromatopsia, relative pupillary afferent defect and bilateral disk oedema in the fundoscopic examination. Visual evoked potential latencies were bilaterally increased, suggesting optic neuropathy...

BACKGROUND: There is a need to improve the diagnostic process of patients suspected of papilledema. In patients with known or suspected idiopathic intracranial hypertension we validated a fundus imaging and perimetric visual field assessment system (COMPASS) performed at a headache centre in comparison to an assessment (Topcon plus OCTOPUS) at a neuroophthalmological clinic. METHODS: For intermethod assessment, blinded fundus images and perimetry from COMPASS versus Topcon plus OCTOPUS were assessed by a neuroophthalmologist...

A young woman presented with blurred vision due to anticholinergic syndrome. We highlight the importance of considering this condition in the context of multiple medications and increased anticholinergic burden. The documented pupil abnormality gives an opportunity to review the syndrome of the reverse (inverse) Argyll Robertson pupil (preserved pupil light response with loss of accommodation). We review other situations in which the reverse Argyll Robertson pupil may occur and its possible mechanism in this case...

Since the last and at the same time first statement of the German ophthalmological societies on the possibilities of reducing myopia progression in childhood and adolescence, many new details and aspects have emerged in clinical research. This second statement updates the previous document and specifies the recommendations on visual and reading behavior as well as on pharmacological and optical therapy options, which have been both refined and newly developed in the meantime.

BACKGROUND: The novel optic neuritis (ON) diagnostic criteria include intereye differences (IED) of optical coherence tomography (OCT) parameters. IED has proven valuable for ON diagnosis in multiple sclerosis but has not been evaluated in aquaporin-4 antibody seropositive neuromyelitis optica spectrum disorders (AQP4+NMOSD). We evaluated the diagnostic accuracy of intereye absolute (IEAD) and percentage difference (IEPD) in AQP4+NMOSD after unilateral ON >6 months before OCT as compared with healthy controls (HC)...

BACKGROUND: To characterise the response to treatment of inaugural optic neuritis (ON) in patients with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). METHODS: We searched the French MOGAD database for adults with inaugural ON with a detailed report of acute treatment modalities and measures of high-contrast best-corrected visual acuity (BCVA) at nadir and after 3 months. Predictors of visual outcomes were assessed by multivariable analysis...

A man in his 30s, who presented with fevers and a diffuse purpuric rash, developed sudden-onset visual loss on day 2. He was unable to perceive light in either eye. Examination by a neurologist confirmed cortical blindness, and the MRI showed subtle juxtacortical infarcts and leptomeningeal enhancement in the occipital region. Further history taken in the patient's native language revealed a history of untreated systemic lupus erythematosus. A diagnosis of central nervous system lupus was made and he was treated promptly with pulse methylprednisolone and cyclophosphamide...

Tolosa-Hunt syndrome (THS) remains a challenging diagnosis for many neurologists. Often believed to be a rare presentation, the classical presentation is known to involve cranial nerves and tissues surrounding the cavernous sinus. Traditionally, a diagnosis of THS is considered when all secondary conditions have been ruled out. Yet, newer findings have elaborated a complex pathogenetic process with some overlap from the IgG4 spectrum of disorders, with which it shares many phenotypic similarities. In this narrative review, we present an updated picture of the condition focusing on the latest developments in the pathogenesis, diagnosis, and clinical management of these two conditions and use illustrative examples to highlight the salient features of this rare presentation...

Subperiosteal orbital hemorrhage usually occurs in the setting of facial or orbital trauma. Non-traumatic subperiosteal orbital hemorrhage (NTSOH) has rarely been reported in literature. The proposed mechanism of NTSOH is the transmission of sudden increase in cranial venous pressure to the orbital veins, which are valveless. We present a case of a 37 year old right-handed woman with a past medical history significant for type 1 diabetes, end-stage renal disease, peripheral artery disease and hypertension who developed NTSOH following an elective revision of a clotted right upper extremity arteriovenous fistula...

A 67-year-old man with rheumatoid arthritis developed recurrent acute onset of stereotyped focal neurological abnormalities. Cerebral imaging showed a mass lesion in the left parieto-occipital lobe. Imaging did not show the time evolution expected in stroke and so he underwent an extensive workup, which was inconclusive. Brain biopsy identified a rheumatoid nodule causing an extensive inflammatory reaction that mimicked a mass. Following treatment with intravenous corticosteroids and rituximab infusions, his clinical condition improved...

Acute idiopathic blind spot enlargement syndrome (AIBSES) is characterized by unilateral visual field loss in the blind spot area, acute onset photopsia, and funduscopically few or no optic disc changes. AIBSES predominantly affects young adults and is often misdiagnosed as optic neuritis because of low awareness. Optical coherence tomography (OCT) has become the gold standard in diagnosing AIBSES as a disease of the outer retina. In our case series, we present three consecutive patients with AIBSES followed prospectively with and without steroid therapy...
