Long-Term Disability Outcomes for Patients With Ischemic Stroke Presenting With Visual Deficits
Background: Ischemic strokes in both the anterior and posterior circulation can lead to visual deficits, which can affect functional ability. Thrombolytic therapies are often withheld to patients with visual deficits because of either being missed on initial evaluation or because of the misconception that their deficits are not as severe or as disabling. Alternatively, delays in patient arrival for emergent evaluation lead to missed opportunities for acute stroke treatment. This retrospective study aims to explore the differences in perceived long-term disability for patients with stroke who present with visual deficit...

Accuracy of Visual Fields in Localizing MRI Lesions in Posterior Cerebral Artery Infarction
Conclusion: In this study of PCA ischemic stroke, VFDs limited to 1 hemifield were accurate in locating the side and quadrant of the MRI visual cortex lesions. However, the quadrantic VFDs sometimes failed to predict that the lesions involved both the superior and inferior quadrants on the same side, largely because those lesions had subtle imaging features that defied accurate radiologic assessment or were out of the reach of the visual field test protocol.

New-onset Oscillopsia in a Patient With a History of Pontine Stroke
Abstract: A 69-year-old man with a history of pontine hemorrhage 2 years ago noticed binocular vertical diplopia after the stroke. On examination, there was a small-angle incomitant left hyperdeviation that did not fit the 3-step test for fourth nerve palsy and incyclotorsion of the higher eye. On motility testing, there was an obvious pendular nystagmus. Resting tremor of the right hand was noticed on neurological examination. Examination of the oropharynx revealed rhythmic oscillations of the soft palate synchronous with the eye oscillations and hand tremor. These findings established a diagnosis of oculopalatal myoc...

Bedside Assessment of Vergence in Stroke Patients
Conclusions: There is only a limited localizing value of vergence deficits in stroke. Parietal lobe infarctions are more frequently associated with insufficient binocular and monocular vergence. Midbrain strokes were too few to draw final conclusions. However the most robust factor to emerge from our data is age. Older subjects show poor slow binocular as well as slow and fast monocular vergence. Extended white matter lesions are also correlated with deficient vergence ability suggesting a role for subcortical wide range connections in maintaining an intact vergence circuitry.

Referral Patterns of Central Retinal Artery Occlusion to an Academic Center Affiliated With a Stroke Center
Background: Central retinal artery occlusion (CRAO) is a medical emergency, and patients who present acutely should be immediately referred to the nearest stroke center. We evaluated practice patterns for CRAO management at one academic center over the last decade. Methods: This was a retrospective study on all adult patients diagnosed with a CRAO seen at one tertiary hospital and outpatient clinic affiliated with a comprehensive stroke center (“our institution”) from 2010 to 2020. Our electronic medical records were searched for CRAO diagnoses, and patient medical records were reviewed. The exclusion criter...

The Frequency of Carotid Intraplaque Hemorrhage on Vessel Wall Imaging in Patients With Retinal Artery Occlusion: A Cross-Sectional Prevalence Study
Conclusions: Carotid IPH is independently associated with RAO. The use of plaque imaging in the evaluation of patients with acute RAO is therefore supported.

Dorsal Midbrain Syndrome: Clinical and Imaging Features in 75 Cases
Conclusions: This large series expands on the clinical profile of DMS. Neoplasms and strokes were the most common causes. Obstructive hydrocephalus alone, identified as a major cause in the largest previously published series, was uncommon. At least 3 neuro-ophthalmic signs were present in nearly all patients, with upgaze deficit as predominant. Unlike an earlier report, this study found no correlation between brain imaging and clinical signs. Neuro-ophthalmic signs persisted even after neoplasms were successfully treated and improved only slightly after stroke. Telephone interviews with patients revealed that diplopia...

Afferent and Efferent Neuro-Ophthalmic Complications of Coronavirus Disease 19
Conclusions: The literature on COVID-associated neuro-ophthalmic disease continues to grow. Afferent neuro-ophthalmic complications associated with COVID-19 include optic neuritis, papillophlebitis, papilledema, visual disturbance associated with posterior reversible encephalopathy syndrome, and vision loss caused by stroke. Efferent neuro-ophthalmic complications associated with COVID-19 include cranial neuropathies, Miller Fisher syndrome, Adie's pupils, ocular myasthenia gravis, nystagmus and eye movement disorders. Proposed mechanisms of neurologic disease include immunologic upregulation, vasodilation and vascular...

SARS-CoV-2 Impairs Vision
Conclusions: This mini review shows that impaired vision may be the initial manifestation of COVID-19, that all sections of the visual tract may be affected and causative for visual impairment in COVID-19 patients, and that SARS-CoV-2 manifests along the visual tract with ischemia, focal infection, and immunological reactions.

New Focus on Endovascular Therapy for Ischemic Stroke
Conclusions: Recent studies underscore the conclusion that timely reperfusion in acute ischemic stroke is the most effective available treatment and that there are a growing number of new scenarios and patients for which interventions maybe applied.

Neuro-Ophthalmologic Features and Outcomes of Thalamic Infarction: A Single-Institutional 10-Year Experience
Conclusions: Thalamic infarction, especially in paramedian territory, can cause a wide variety of neuro-ophthalmologic manifestations, including vertical gaze palsy, skew deviation, and third nerve palsy. Although most oculomotor abnormalities resolve spontaneously within a few months, some may persist for years when the deficits remain unimproved for more than 3 months after stroke.

The Clinical and Imaging Profile of Skew Deviation: A Study of 157 Cases
Conclusions: The amplitude of misalignment in skew deviation varies widely but is generally 5 PD or less. When misalignment is 3 PD or less, patients report blurred vision rather than diplopia. Skew deviation is usually accompanied by other neurologic signs reflecting brainstem dysfunction. Yet there is a small subgroup in which vertical misalignment is an isolated sign, and there are no supporting brain imaging abnormalities. The main cause of skew deviation is ischemic stroke, which affects not only the brainstem but also the thalamus. Diplopia from skew deviation frequently persists, in which case prism spectacles m...
