Increased Intracranial Pressure Without Hydrocephalus Associated With Spinal Cord Tumor: Literature Review
Zhou, Yujia MD, MS; McClelland, Collin M. MD; Lee, Michael S. MD
doi : 10.1097/WNO.0000000000001026
March 2021 - Volume 41 - Issue 1 - p 13-18
Spinal cord tumors (SCTs) may rarely cause increased intracranial pressure without hydrocephalus (IICPWH). A review of the English literature published after 1970 revealed 29 cases of IICPWH secondary to SCT. The following data were acquired: demographics, tumor characteristics, ophthalmic and neurological manifestations, and cerebral spinal fluid (CSF) features. We summarize the existing literature regarding various theories of pathophysiology, spinal imaging recommendations, and treatment modalities used in managing such patients. Patients with papilledema who also have neurological signs or symptoms of myelopathy or elevated CSF protein particularly in the setting of an atypical demographic for pseudotumor cerebri should raise a suspicion for a spinal tumor and prompt further investigation with a spinal MRI.

Visual acuity has been a significant outcome measure in clinical trials for patients suffering from neuro-ophthalmological diseases and multiple sclerosis; however, there are limited data on the comparison of various testing strategies in pediatric patients with these disorders. Clinical trials using vision as an outcome could include a variety of tools to assess the acuity, including 2-m and 4-m standardized retroilluminated charts.
Site of Origin of the Ophthalmic Artery Influences the Risk for Retinal Versus Cerebral Embolic Events
Rossin, Elizabeth J. MD, PhD; Gilbert, Aubrey L. MD, PhD; Koen, Nicholas BS; Leslie-Mazwi, Thabele M. MD; Cunnane, Mary E. MD; Rizzo, Joseph F. III MD
doi : 10.1097/WNO.0000000000000883
March 2021 - Volume 41 - Issue 1 - p 24-28
Embolic events leading to retinal ischemia or cerebral ischemia share common risk factors; however, it has been well documented that the rate of concurrent cerebral infarction is higher in patients with a history of transient ischemic attack (TIA) than in those with monocular vision loss (MVL) due to retinal ischemia. Despite the fact that emboli to the ophthalmic artery (OA) and middle cerebral artery share the internal carotid artery (ICA) as a common origin or transit for emboli, the asymmetry in their final destination has not been fully explained. We hypothesize that the anatomic location of the OA takeoff from the ICA may contribute to the differential flow of small emboli to the retinal circulation vs the cerebral circulation.
Neuro-Ophthalmologic Features and Outcomes of Thalamic Infarction: A Single-Institutional 10-Year Experience
Moon, Yeji MD; Eah, Kyu Sang MD; Lee, Eun-Jae MD, PhD; Kang, Dong-Wha MD, PhD; Kwon, Sun Uck MD, PhD; Kim, Jong Sung MD, PhD; Lim, Hyun Taek MD, PhD

The continued increase in idiopathic intracranial hypertension (IIH) prevalence has many implications for societal health care. Its potential vision-threatening consequences make ophthalmologists key players in its diagnosis and management. Newer technology such as optical coherence tomography angiography (OCT-A) enables evaluation of the branching complexity of the peripapillary capillary plexus, a region where accurate imaging via fluorescein angiography was previously limited.
Magnetic Resonance Imaging Abnormalities of the Optic Nerve Sheath and Intracranial Internal Carotid Artery in Giant Cell Arteritis
Gospe, Sidney M. III MD, PhD; Amrhein, Timothy J. MD; Malinzak, Michael D. MD, PhD; Bhatti, M. Tariq MD; Mettu, Pradeep MD; El-Dairi, Mays A. MD

Giant cell arteritis (GCA) is an important diagnostic consideration in elderly patients with vision changes. Superficial temporal artery biopsy (TAB) has long been considered the gold standard diagnostic approach for GCA, but MRI has gained interest as an alternative diagnostic modality. Although most of the literature has focused on imaging abnormalities of branches of the external carotid artery, there have been a few reports of GCA-related inflammatory involvement of the orbit and internal carotid arteries (ICAs) on MRI.
Shortened Pattern Electroretinogram Latency and Impaired Autoregulatory Dynamics to Steady-State Stimuli in Patients With Multiple Sclerosis
Jiang, Hong MD, PhD; Gameiro, Giovana R.; Hu, Huiling MD, PhD; Monsalve, Pedro F. MD; Dong, Chuanchui PhD; Hernandez, Jeffrey RN; Delgado, Silvia R. MD; Porciatti, Vittorio D. PhD; Wang, Jianhua MD, PhD

The steady-state pattern electroretinogram (PERG) is a sensitive measure of retinal ganglion cell (RGC) function that includes within-test progressive changes—adaptation—reflecting RGC autoregulatory dynamics. Comprehensive PERG assessment in patients with multiple sclerosis (MS) (with or without optic neuritis [ON]) may provide unique information about RGC dysfunction and its progression, as well as a comparison between functional loss and structural loss as measured by optical coherence tomography (OCT). The goal of this project was to measure steady-state PERG components and their associations with intraretinal layer thicknesses in MS.
The Clinical and Imaging Profile of Skew Deviation: A Study of 157 Cases
Walter, Eyal MD; Trobe, Jonathan D. MD
doi : 10.1097/WNO.0000000000000915
March 2021 - Volume 41 - Issue 1 - p 69-76
Skew deviation, a vertical misalignment of the eyes caused by a lesion in the vestibulo-ocular pathway, is a common manifestation of brainstem dysfunction, yet comprehensive information about its clinical profile is lacking. The aim of this study was to document presenting symptoms, causes, ocular alignment features, accompanying neurologic signs, pertinent brain imaging abnormalities, and measures used to relieve diplopia.
Optical Coherence Tomography Neuro-Toolbox for the Diagnosis and Management of Papilledema, Optic Disc Edema, and Pseudopapilledema
Sibony, Patrick A. MD; Kupersmith, Mark J. MD; Kardon, Randy H. MD, PhD

March 2021 - Volume 41 - Issue 1 - p 77-92
Distinguishing optic disc edema from pseudopapilledema is a common, sometimes challenging clinical problem. Advances in spectral-domain optical coherence tomography (SD-OCT) of the optic nerve head (ONH) has proven to be a cost effective, noninvasive, outpatient procedure that may help. At its core are tools that quantify the thickness of the retinal nerve fiber layer (RNFL) and ganglion cell–inner plexiform layer (GC-IPL). The SD-OCT also provides a set of tools that may be qualitatively interpreted in the same way that we read an MRI. They include the transverse axial, en face, and circular tomogram. Our goal is to describe a practical office-based set of tools using SD-OCT in the diagnosis and monitoring of papilledema, optic disc edema, and pseudopapilledema.

A woman presented with bilateral visual disturbances that had been diagnosed as visual snow. Dilated ophthalmic examination and multimodal imaging were strongly suggestive of birdshot chorioretinopathy, meriting initiation of systemic immunomodulatory therapy. Visual snow requires a thorough ophthalmologic exam to exclude other ocular diseases.

Neurovascular compression is a rare but potentially treatable cause of optic neuropathy. Although incidental contact of the cisternal optic nerve and internal carotid artery (ICA) is common, compressive optic neuropathy occurring within the orbital apex has not been comprehensively described. We report a case of intra-orbital and intracanalicular optic nerve compression due to an ectatic ICA in a patient with congenital absence of the contralateral ICA. This report describes the complementary roles of advanced neuroimaging and neuro-ophthalmologic examination in rendering the diagnosis.

A 78-year-old man suffered sudden visual loss of his right eye. Five years earlier, he had experienced vision loss of his left eye due to central retinal artery occlusion (CRAO); back then, the etiology for the CRAO was not established. Current ocular ultrasound depicted a hyperechoic spot within the optic nerve in both eyes. Echocardiography identified a calcified mass adherent to the mitral valve as the embolic source of the CRAO. This case shows the value of ocular B-mode ultrasound in demonstration and proof of the etiology for CRAO.

Inner nuclear layer (INL) microcysts have been reported in diseases affecting the optic nerve. The new ocular imaging techniques detect minimal structural alterations at the macula and correlate these findings to different etiologies with less invasive procedures. The relationship between ganglion cells distribution at the macula and chiasmal nerve fibers enables the diagnosis and location of neurological lesions by new generation optical coherence tomography (SD-OCT) imaging devices. We report the evaluation of a patient with a history of optic nerve trauma and macular INL microcysts with multicolor SD-OCT technology that shows a pattern that localizes the lesion to the left optic nerve and proximal segment of the chiasm.

A 43-year-old woman presented with a right-sided visual field defect in the right eye. The visual acuity was normal and there was a right relative afferent pupillary defect. Formal visual field testing revealed a junctional scotoma of Traquair. The fundus examination showed optic atrophy in the right eye and optical coherence tomography demonstrated unilateral band atrophy. Neuroimaging revealed a sellar and suprasellar cystic pituitary adenoma for which she underwent a transsphenoidal drainage. We demonstrate the clinical and radiographic features of the junctional scotoma of Traquair and describe the differentiating features vs the junctional scotoma.

Optical coherence tomography angiography is one of the latest noninvasive imaging modalities for visualizing the vasculature of retina and choroid. We describe its application in the diagnosis, treatment, and monitoring of a patient with peripapillary choroidal neovascular membrane in the setting of idiopathic intracranial hypertension, who responded well to a course of ranibizumab intravitreal injections.

A 3-month-old male infant appeared on multiple clinical examinations to have acutely developed bilateral retrogeniculate blindness. Electroencephalography showed focal status epilepticus confined to the left posterior cerebral hemisphere. MRI demonstrated restricted diffusion in the domain of the left posterior cerebral artery consistent with acute stroke. Notably, the restricted diffusion extended across the midline in the splenium of the corpus callosum. This splenial sign may be the imaging correlate of cerebral diaschisis, a well-described phenomenon in which patients with new brain lesions develop acutely impaired neurologic function in related but nonlesioned brain regions. Diaschisis has been posited as the explanation for the temporary bilateral blindness in adult patients suffering from unilateral occipital infarctions.

We present a case of vision loss secondary to neurosarcoidosis, which initially presented with severe bilateral vision loss, temporal headaches, and elevated erythrocyte sedimentation rate, concerning for giant cell arteritis. However, temporal artery biopsy was negative. Initial neuroimaging features were misinterpreted to represent a meningioma that did not account for his clinical presentation. Clinical course, including atypically rapid enlargement of presumed meningioma, development of skin lesions, appearance of optic nerve enhancement on MRI, and steroid response, strongly increased suspicion for sarcoidosis. Biopsy of a skin lesion demonstrated noncaseating granulomatous inflammation, consistent with sarcoidosis.

Giant cell arteritis (GCA) is a medium-to-large vessel vasculitis of the elderly. Common constitutional clinical features include headache, scalp tenderness, and jaw claudication. Severe unilateral or bilateral visual loss is the most feared ophthalmic complication of GCA. Scalp necrosis is a known ischemic complication of GCA with approximately 100 cases reported in the literature to date. We report a case of scalp pain and an erythematous cutaneous lesion in the distribution of ophthalmic division of the trigeminal nerve that mimicked herpes zoster ophthalmicus. A temporal artery biopsy was positive for GCA, and small vessel arteritis was seen at the time of simultaneous skin biopsy. To the best of our knowledge, this is the first such report in the English language ophthalmic literature.

A 31-year-old healthy Asian man presented with new headaches and blurred vision. He was found to have bilateral optic disc edema (ODE) and peripapillary subretinal fluid and was initially investigated for causes of raised intracranial pressure. After referral to neuro-ophthalmology, he received a diagnosis of Vogt–Koyanagi–Harada (VKH) disease and his symptoms, ODE, and vision improved promptly with prednisone treatment. HLA typing was performed and returned positive for the HLA-DRB1*04 subtype. Although VKH disease usually presents with granulomatous uveitis or serous retinal detachments, ODE may manifest early in the disease course. Those with ODE in VKH disease are believed to be older and female, but this case demonstrates that these findings were also seen in a young man.

A 36-year-old apparently healthy man presented with acute onset of diplopia. Examination demonstrated left sixth nerve palsy with 3 retinal hemorrhages noted in one eye. Gadolinium-enhanced high-resolution skull base MRI revealed left sixth nerve enhancement involving the cisternal segment. Complete blood count, cerebrospinal fluid analysis, bone marrow biopsy, and flow cytometry confirmed acute T-cell lymphoblastic leukemia with central nervous system involvement. This case demonstrates the value of high-resolution MRI in the evaluation of cranial nerve palsy in young adults and also emphasizes the importance of systemic work up in these cases, particularly when retinal findings are present.

An 81-year-old man with a history of metastatic melanoma presented with sudden onset of painless, binocular vertical diplopia. The clinical examination was consistent with a right fourth nerve palsy. An MRI of the head revealed a mass dorsal to the right tectum at the level of the inferior colliculus. An MRI just 4 months prior did not show a lesion in that location. An MRA of the head did not show an aneurysm. This is a rare case of an isolated fourth nerve palsy believed to be due to metastatic melanoma compressing the nerve along the dorsal midbrain.

A 42-year-old Algerian man presented for binocular oblique diplopia, hypersomnolence with drop attacks, bilateral hearing loss, and thoracic pain. He had a right thalamomesencephalic hemorrhage due to an underlying cavernous malformation treated with subtotal surgical resection. On neuro-ophthalmic examination, the patient had a left relative afferent pupillary defect and a right oculosympathetic efferent pupillary defect (i.e., Horner syndrome) in addition to other thalamomesencephalic eye and neurologic signs (right fourth nerve palsy, hearing loss, hemiparesis, and thalamic pain). Clinicians should recognize the localizing value of this unique constellation of mesencephalic afferent and efferent pupillary defects.
