Buzzing Sympathetic Nerves: A New Test to Enhance Anisocoria in Horner's Syndrome.

Front Neurol 2019 21;10:107. Epub 2019 Feb 21.

Department of Ophthalmology, University Hospital Zurich, University of Zurich, Zurich, Switzerland.

Patients with suspected Horner's syndrome having equivocal pupil dilation lag and pharmacologic testing may undergo unnecessary MR imaging and work up in the case of false positive pupil test results. Our goal was to increase the diagnostic accuracy of pupillometry by accentuating the inter-ocular asymmetry of sympathetic innervation to the iris dilator with surface electrical stimulation of the median nerve using a standard electromyography machine. We hypothesized that an accentuated difference in sympathetic response between the two eyes would facilitate the diagnosis of Horner's syndrome. Read More

A 30 s test for quantitative assessment of a relative afferent pupillary defect (RAPD): the infrared pupillary asymmetry (IPA).

J Neurol 2019 Apr 12;266(4):969-974. Epub 2019 Feb 12.

Department of Neuro-ophthalmology, Moorfields Eye Hospital, 162 City Road, London, EC1V 2PD, UK.

Background: Detection of a relative afferent pupillary defect (RAPD) by the swinging-light test can be challenging in clinical practice (dark eyes, anisocoria, dark environment).

Response anisocoria in the pupillary light and darkness reflex.

Eur J Neurosci 2018 Dec 24;48(11):3379-3388. Epub 2018 Oct 24.

Centre for Neuroscience Studies, Queen's University, Kingston, Ontario, Canada.

The pupil constricts or dilates in response to a luminance increase or decrease, and these transient pupillary responses are controlled by the parasympathetic and sympathetic pathways. Although pupillary responses of the two eyes are highly correlated, they are not always identical (referred to as anisocoria). For example, there are unequal direct and consensual pupillary constriction responses after an increase in luminance to one eye. Read More

Long-Term Follow-Up in Children with Anisocoria: Cocaine Test Results and Patient Outcome.

J Ophthalmol 2017 4;2017:7575040. Epub 2017 Dec 4.

Department of Ophthalmology, University Hospital Zurich, Frauenklinikstrasse 24, CH-8091 Zurich, Switzerland.

Background: Evaluation of anisocoria including pharmacological testing for Horner's syndrome in the pediatric population is challenging in view of potential serious underlying disease. We describe cocaine test results, outcome of systemic investigation, and long-term follow-up in children with anisocoria.

Methods: Retrospective review of medical records and phone interview of consecutive pediatric patients (<18 years old) who underwent cocaine testing from August 2007 to July 2015 at a tertiary referral centre. Read More

A Case of Synchronised Pupillary and Nasal Cycling: Evidence for a Central Autonomic Pendulum?

Neuroophthalmology 2017 Oct 8;41(5):241-246. Epub 2017 May 8.

Husie Health Centre, Department of General Practice, Skane University Hospital, Malmö, Sweden.

We previously reported that some healthy individuals show alternating anisocoria. We now describe one such individual who also exhibits a classic nasal cycle (alternating periods of nasal congestion and decongestion). We made measurements of his pupil asymmetry and nasal asymmetry at 21 different time points and found that these variables were always synchronised such that greater nasal airflow was invariably found on the same side as the larger pupil.

"Crying without tears" as an early diagnostic sign-post of triple A (Allgrove) syndrome: two case reports.

BMC Pediatr 2018 01 15;18(1). Epub 2018 Jan 15.

Department of Pediatrics, Medizinische Fakultät, Technische Universität Dresden, Dresden, Germany.

Background: Triple A syndrome (or Allgrove syndrome) is a rare autosomal recessive disorder characterized by alacrima, achalasia, adrenal insufficiency and autonomic/neurological abnormalities. The majority of cases are caused by mutations in the AAAS gene located on chromosome 12q13. However, the clinical picture as well as genetic testing may be complex since symptomatology is variable and mutations cannot be identified in all clinically diagnosed patients. Read More

Horner Syndrome: A Clinical Review.

Authors:
Timothy J Martin

ACS Chem Neurosci 2018 02 20;9(2):177-186. Epub 2017 Dec 20.

Department of Ophthalmology, Wake Forest University School of Medicine , Wiston-Salem, North Carolina 27157, United States.

Horner syndrome results from an interruption of the oculosympathetic pathway. Patients with Horner syndrome present with a slightly droopy upper lid and a smaller pupil on the affected side; less commonly, there is a deficiency of sweating over the brow or face on the affected side. This condition does not usually cause vision problems or other significant symptoms, but is important as a warning sign that the oculosympathetic pathway has been interrupted, potentially with serious and even life-threatening processes.
