Secondary Stroke Prevention and Management for the Neuro-Ophthalmologist
Conclusions: The optimal treatment to prevent stroke recurrence is determined by the etiology of stroke. After stroke workup, patients will typically be placed on proper medical therapy for the appropriate duration in addition to counseling on lifestyle modifications to reduce the risk of recurrent strokes. For complex patients, it is reasonable for providers to consider patient referral to stroke specialists for further aid in selection of appropriate medical therapy.

New Standards of Care in Ischemic Stroke
Conclusions: Endovascular therapy is now standard of care for eligible patients with anterior large vessel occlusions. Prolonged cardiac monitoring is recommended for patients with cryptogenic stroke. The novel anticoagulants are an alternative to warfarin in patients with AF.

Updates in the Management of Cryptogenic Stroke and Patent Foramen Ovale
Conclusions: Stroke management is based on evaluation of individual patient-risk factors. Evaluation and treatment is ideally directed by a vascular neurologist to ensure optimal secondary prevention, especially in cases where an underlying etiology is not identified on initial workup.

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...

Risk of Acute Ischemic Stroke in Patients With Monocular Vision Loss of Vascular Etiology
Conclusions: Patients with MVL of vascular etiology such as TMVL, CRAO, or BRAO may have up to 19.5% risk of concurrent ischemic stroke, even when there are no other neurologic deficits. These strokes were detected acutely with brain MRI using DWI but were missed on CT.

Stroke Rate, Subtype, and Cardiovascular Risk Factors in Nonarteritic Anterior Ischemic Optic Neuropathy: A Population-Based Study
Conclusions: NAION does not confer an increased risk of symptomatic stroke beyond the risk posed by age and existing vascular risk factors.

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.

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...

Optic Neuropathy and Stroke Secondary to Invasive Aspergillus in an Immunocompetent Patient
We describe a unique case of disseminated central nervous system aspergillosis, initially presenting as an optic neuropathy, with subsequent stroke in multiple vascular territories.

Idiopathic Intracranial Hypertension Progressing to Venous Sinus Thrombosis, Subarachnoid Hemorrhage, and Stroke
We describe a young woman with typical IIH who underwent lumbar puncture and was treated with a short course of high-dose corticosteroids followed by acetazolamide. She subsequently developed CVST, subarachnoid hemorrhage, and stroke. Risk factors that may have resulted in CVST are discussed.

Patterns of Cortical Visual Field Defects From Embolic Stroke Explained by the Anastomotic Organization of Vascular Microlobules
Abstract: The cerebral cortex is supplied by vascular microlobules, each comprised of a half dozen penetrating arterioles that surround a central draining venule. The surface arterioles that feed the penetrating arterioles are interconnected via an extensively anastomotic plexus. Embolic occlusion of a small surface arteriole rarely produces a local infarct, because collateral blood flow is available through the vascular reticulum. Collateral flow also protects against infarct after occlusion of a single penetrating arteriole. Cortical infarction requires blockage of a major arterial trunk, with arrest of blood flow to a...

Splenial Restricted Diffusion as MRI Correlate of Diaschisis in a Blind Infant With Unilateral Posterior Cerebral Artery Stroke
Abstract: 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 acutel...
