Telehealth provides health care to a patient from a provider at a distant location. Before the COVID-19 pandemic, adoption of telehealth modalities was increasing slowly but steadily. During the public health emergency, rapid widespread telehealth implementation has been encouraged to promote patient and provider safety and preserve access to health care. ⋯ Telehealth is an increasingly recognized means of health care delivery. Tele-Neuro-Ophthalmology adoption is necessary for the sake of our patients, the survival of our subspecialty, and the education of our trainees and students. Telehealth does not supplant but supplements and complements in-person neuro-ophthalmologic care. Innovations in digital optical fundus photography, mobile vision testing applications, artificial intelligence, and principles of channel management will facilitate further adoption of tele-neuro-ophthalmology and bring the specialty to the leading edge of health care delivery.

Concussion, particularly in relation to sports and combat activities, is increasingly recognized as a potential cause of both short- and long-term neurologic sequelae. This review will focus on the neuro-ophthalmologic findings associated with concussion, the current tests for concussion, and the potential for visual performance measures to improve our detection and assessment of concussions. ⋯ Concusssion is associated with many neuro-ophthalmologic signs and symptoms. Visual performance measures enhance the detection and management of concussion, and future studies are under way to further incorporate vision-based testing into sideline diagnosis and long-term clinical assessments.

Review Case Reports
Primary spontaneous cerebrospinal fluid leaks and idiopathic intracranial hypertension.
Idiopathic intracranial hypertension (IIH) is increasingly recognized as a cause of spontaneous cerebrospinal fluid (CSF) leak in the otolarnygological and neurosurgical literature. The diagnosis of IIH in patients with spontaneous CSF leaks typically is made a few weeks after surgical repair of the leak when symptoms and signs of elevated intracranial pressure (ICP) appear. ⋯ CSF leak occasionally may keep IIH patients symptom-free; however, classic symptoms and signs of intracranial hypertension may develop after a CSF leak is repaired, exposing these patients to a high risk of recurrence of the leak unless an ICP-lowering intervention is performed.

Review Case Reports
Positive apraclonidine test 36 hours after acute onset of horner syndrome in dorsolateral pontomedullary stroke.
A 40-year-old man developed a Horner syndrome as part of a dorsolateral medullary brainstem infarction. Thirty-six hours after the onset of the stroke, topical instillation of 0.5% apraclonidine produced reversal of anisocoria. This is the first case in which apraclonidine testing has been applied to a patient with a Horner syndrome caused by a lesion in the first segment of the oculosympathetic pathway and the shortest reported interval between clinical manifestations of the lesion and apraclonidine-induced reversal of anisocoria. A review of all reported cases of apraclonidine testing in Horner syndrome suggests that this is a promising diagnostic adjunct that must be validated in larger studies.
