[PMID: 30042794 DOI: 10.1080/01658107.2017.1381853] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2017] [Revised: 09/12/2017] [Accepted: 09/16/2017] [Indexed: 10/18/2022] Open
Abstract
Ecchordosis physaliphora (EP) is a rare non-malignant mass that originates from remains of the notochord and is typically asymptomatic. A 42-year-old man presented with sudden onset of painless horizontal diplopia and his neurological exam showed sixth cranial nerve palsy. Magnetic resonance imaging (MRI) identified a non-enhanced retroclival mass (EP) with increased signal intensity on T2 and decreased signal intensity on T1-weighted sequences. He was treated with methylprednisolone, completely recovered in four weeks and has remained symptom free. Conservative management should be attempted before surgery in all cases since symptoms can resolve spontaneously and EP could be an incidental finding.

Capturing saccades in multiple sclerosis with a digitized test of rapid number naming. J Neurol 2017; 264:989-998. [PMID: 28389741 DOI: 10.1007/s00415-017-8484-1] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2017] [Revised: 04/01/2017] [Accepted: 04/03/2017] [Indexed: 01/25/2023]
Abstract
The King-Devick (K-D) test of rapid number naming is a visual performance measure that captures saccadic eye movements. Patients with multiple sclerosis (MS) have slowed K-D test times associated with neurologic disability and reduced quality of life. We assessed eye movements during the K-D test to identify characteristics associated with slowed times. Participants performed a computerized K-D test with video-oculography. The 25-Item National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25) and its 10-Item Neuro-Ophthalmic Supplement measured vision-specific quality of life (VSQOL). Among 25 participants with MS (age 37 ± 10 years, range 20-59) and 42 controls (age 33 ± 9 years, range 19-54), MS was associated with significantly longer (worse) K-D times (58.2 ± 19.8 vs. 43.8 ± 8.6 s, P = 0.001, linear regression models, accounting for age). In MS, test times were slower among patients with higher (worse) Expanded Disability Status Scale scores (P = 0.01). Average inter-saccadic intervals (ISI) were significantly longer in MS participants compared to controls (362 ± 103 vs. 286 ± 50 ms, P = 0.001), and were highly associated with prolonged K-D times in MS (P = 0.006). MS participants generated greater numbers of saccades (P = 0.007). VSQOL scores were reduced in MS patients with longer (worse) K-D times (P = 0.04-0.001) and longer ISI (P = 0.002-0.001). Patients with MS have slowed K-D times that may be attributable to prolonged ISI and greater numbers of saccades. The K-D test and its requisite eye movements capture VSQOL and make rapid number naming a strong candidate efferent visual performance measure in MS.

Abstract
PURPOSE OF REVIEW To review the various efferent visual system disorders associated with multiple sclerosis (MS). RECENT FINDINGS Studies have supported the use of internuclear ophthalmoplegia, a model to study effects of fatigue and heat in MS patients. SUMMARY There are a host of efferent ocular manifestations that can present throughout the course of MS. These may manifest as blurred vision, potentially misleading both the patient and clinician to suspect an afferent visual deficit. Other efferent symptoms include diplopia, oscillopsia, and vertigo. The efferent system can be divided into broad categories: supranuclear, internuclear, nuclear, and gaze-holding systems. This review will briefly touch on the anatomy as well as the signs and symptoms associated with MS-related dysfunction involving these systems.

Abstract
PURPOSE OF REVIEW Radiologic imaging is indispensible for the diagnosis and management of many neuro-ophthalmologic conditions. Advances in the radioimaging of neuro-ophthalmologic disorders may evolve from the clinical or the radiological side, meaning there is a constant stream of new information for the clinician. RECENT FINDINGS Functional MRI, diffusion tensor MRI, magnetization transfer imaging, and magnetic resonance spectroscopy are examples of nonstandard radiographic techniques, which have expanded the knowledge of neuro-ophthalmologic conditions. Studies using conventional MRI have also led to advances in understanding optic neuropathies, the ocular motor system, pseudotumor cerebri, posterior reversible encephalopathy syndrome and migraine. SUMMARY This article discusses recent radiologic advances relevant to neuro-ophthalmology.
