Spectral-domain (SD-) optical coherence tomography (OCT) can reliably measure axonal (peripapillary retinal nerve fiber layer [pRNFL]) and neuronal (macular ganglion cell + inner plexiform layer [GCIPL]) thinning in the retina. Measurements from 2 commonly used SD-OCT devices are often pooled together in multiple sclerosis (MS) studies and clinical trials despite software and segmentation algorithm differences; however, individual pRNFL and GCIPL thickness measurements are not interchangeable between devices. In some circumstances, such as in the absence of a consistent OCT segmentation algorithm across platforms, a conversion equation to transform measurements between devices may be useful to facilitate pooling of data.

doi : 10.1097/WNO.0000000000001630
To determine whether patients with biopsy-confirmed optic nerve glioma differ in clinical features and outcomes from those diagnosed by neuroradiologic imaging alone. Methods: Retrospective comparative analysis. Pilocytic astrocytomas (PAs) and gliomas of the optic nerve were identified through ICD-O codes in the Surveillance, Epidemiology, and End Results (SEER) cancer registry from 1975 through 2017.
Optic Disc Drusen in Patients With Ocular Hypertension: A Case Series and Review of the Literature.
Kohli, Darrell MD; Chen, John J. MD, PhD; Bhatti, M. Tariq MD; Moore-Weiss, Jodi M. OD; Roddy, Gavin W. MD, PhD
doi : 10.1097/WNO.0000000000001647
The identification of glaucomatous optic neuropathy in the setting of optic disc drusen (ODD) is a challenge, and the decision of whether to offer treatment in the form of intraocular pressure (IOP) reduction is controversial. Here, we present a series of patients with coexisting ocular hypertension and ODD to evaluate clinical features, treatment options, and progression of optic neuropathy. In addition, a review of the literature on ODD with elevated IOP is provided.

Kruger, Joshua M. MD, PhD; Almer, Zina MD; Almog, Yehoshua MD; Aloni, Eyal MD; Bachar-Zipori, Anat MD; Bialer, Omer MD; Ben-Bassat Mizrachi, Iris MD; Horowitz, Josepha MD; Huna-Baron, Ruth MD; Ivanir, Yair MD; Jabaly-Habib, Haneen MD; Klein, Ainat MD; Krasnitz, Irena MD; Leiba, Hana MD; Maharshak, Idit MD; Marcus, Mira MD; Ostashinsky, Michal MD; Paul, Michael MD; Rappoport, Daniel MD; Stiebel-Kalish, Hadas MD; Rath, Eitan Z. MD; Tam, Guy MD; Walter, Eyal MD; Johnson, Chris A. PhD
doi : 10.1097/WNO.0000000000001622
A multitude of terms have been used to describe automated visual field abnormalities. To date, there is no universally accepted system of definitions or guidelines. Variability among clinicians creates the risk of miscommunication and the compromise of patient care. The purposes of this study were to 1) assess the degree of consistency among a group of neuro-ophthalmologists in the description of visual field abnormalities and 2) to create a consensus statement with standardized terminology and definitions.

Brady, Taylor MD; Vegunta, Sravanthi MD; Crum, Alison V. MD; Marx, Douglas MD; Patel, Bhupendra C. K. MD; Seay, Meagan D. DO; Schmidt, Richard H. MD, PhD; Warner, Judith E. A. MD; Digre, Kathleen B. MD; Katz, Bradley J. MD, PhD
doi : 10.1097/WNO.0000000000001594
This study evaluates the effectiveness of a multidisciplinary protocol for management of patients with papilledema and vision loss secondary to increased intracranial pressure. Methods: Retrospective record review of all adult patients who presented with vision-threatening papilledema (VTPE) and were treated under this protocol. Patients are admitted for lumbar drain placement and diuretics and followed daily to determine if they may be managed medically or require surgery (optic nerve sheath fenestration [ONSF] and/or cerebrospinal fluid [CSF] shunting). Results: Nineteen patients were included.
Comparison of the Range of Lumbar Cerebrospinal Fluid Pressure in Adults With Normal Cerebrospinal Fluid Pressure and in Idiopathic Intracranial Hypertension.
Bateman, David E. MD, FRCP; Wingrove, Barbara MS
doi : 10.1097/WNO.0000000000001578
Lumbar puncture CSF pressure measurements in a large group of adults (116) having lumbar puncture (LP) for diagnostic reasons with no clinical indication of raised intracranial pressure were used to establish the normal range of CSF pressure.
Can Lumbar Puncture Be Safely Deferred in Patients With Mild Presumed Idiopathic Intracranial Hypertension?.
Vosoughi, Amir R. BSc; Margolin, Edward A. MD; Micieli, Jonathan A. MD, CM
doi : 10.1097/WNO.0000000000001411
Lumbar puncture (LP) is considered an essential component of the diagnosis of idiopathic intracranial hypertension (IIH) and ruling out IIH mimics, such as meningeal inflammation and neoplastic disease. Such mimics are unlikely in patients who are systemically well and fit the clinical demographic of IIH. It is important to take into account the risks of performing a LP as patients commonly experience mild adverse effects and infrequently more serious ones including psychological distress.
Early Retinal Microcirculation in Nonfunctioning Pituitary Adenomas Without Visual Field Defects Using Optical Coherence Tomography Angiography.
Chou, Yuyu MD; Wang, Xuqian MD; Wang, Ye PhD; Gan, Linyang MD; Xing, Bing MD; You, Hui MD; Ma, Jin PhD; Zhong, Yong PhD
doi : 10.1097/WNO.0000000000001562
For patients with nonfunctioning pituitary adenoma (NFPA) without manifesting visual acuity impairment or visual field defect (VFD), more sensitive and objective assessment methods will allow earlier detection before irreversible damage to the visual system. This study aimed to evaluate retinal vessel densities (VDs) alterations in these patients using optical coherence tomography angiography and to determine its diagnostic abilities.
Long-Term Disability Outcomes for Patients With Ischemic Stroke Presenting With Visual Deficits.
Johnson, Natalie; Nisar, Tariq MPH; Criswell, Amber BA, CCRC; McCane, David BA, CCRC; Lee, Jason RN, BNS, SCRN; Chiu, David MD; Gadhia, Rajan MD
doi : 10.1097/WNO.0000000000001624
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.
Sharp Edge Eye Syndrome: A Case Report and Survey of Self-Identified Individuals.
Reynolds, Merrick S. MS; Katz, Bradley J. MD, PhD; Digre, Kathleen B. MD; Brintz, Ben J. PhD; Olson, Lenora M. PhD; Warner, Judith E. A. MD
doi : 10.1097/WNO.0000000000001650
Sharp edge eye syndrome (SEES), sometimes known as visual looming syndrome, is a condition in which the patient experiences ocular pain or discomfort when viewing or mentally picturing sharp objects and edges. Patients may present for medical care because they perceive the condition to represent an ophthalmic problem or a sign of a more serious underlying condition. An individual case report of SEES is included to aid in illustrating syndrome characteristics.

Retinal Input to the Primate Lateral Geniculate Nucleus Revealed by Injection of a Different Label Into Each Eye.
Spahr, Zachary R. BA; Economides, John R. PhD; Horton, Jonathan C. MD, PhD
doi : 10.1097/WNO.0000000000001472
AB The primate lateral geniculate nucleus has long been a favorite structure among anatomists because of its striking lamination. It has been shown that each lamina receives input from a different eye using various single label techniques but never by double labeling. Here, we illustrate the organization of retinal inputs to the lateral geniculate nucleus by injection of cholera toxin-B conjugated to Alexa Fluor-488 into the right eye and cholera toxin-B conjugated to Alexa Fluor-594 into the left eye.
