Antiphospholipid syndrome and neurofibromatosis type I: a coincidence or new association?

Arq Bras Oftalmol 2019 Mar-Apr;82(2):155-157

Department of Neuro-radiology, Sheikh Khalifa Hospital, Abu Dhabi, UAE.

Numerous studies have reported on structural vascular anomalies and ischemia associated with neurofibromatosis type 1 that are thought to stem from dysfunction of neurofibromin, the neurofibromatosis type 1 protein. Documented cases of associated antiphospholipid syndrome fulfilling the accepted diagnostic criteria are exceptionally rare, with only three cases reported in the literature. Here, we report on a patient with neurofibromatosis type 1 and a history of spontaneous abortions presenting with sudden vision loss in the right eye and swelling of the optic nerve head. Read More

Characterization of retinal microvasculature in acute non-arteritic anterior ischemic optic neuropathy using the retinal functional imager: a prospective case series.

Eye Vis (Lond) 2019 6;6. Epub 2019 Jan 6.

2Bascom Palmer Eye Institute, University of Miami, Miller School of Medicine, 900 NW 17th Street, Miami, FL 33136 USA.

Background: Non-arteritic anterior ischemic optic neuropathy (NAION) is the most common cause of acute optic neuropathy in patients over 50 years of age, and many affected individuals are left with permanent visual deficits. Despite the frequency of NAION and its often devastating effects on vision, no effective treatment has been established. Further understanding of the acute vascular effects in NAION, using advanced ophthalmic imaging techniques like the retinal function imager, may shed light on potential treatment targets. Read More

Subclinical Leber's hereditary optic neuropathy with pediatric acute spinal cord onset: more than meets the eye.

BMC Neurol 2018 Dec 27;18(1):220. Epub 2018 Dec 27.

Department of Pathophysiology and Transplantation, Dino Ferrari Centre, University of Milan, Milan, Italy.

Background: Leber's hereditary optic neuropathy (LHON) is a mitochondrial disease characterized by visual loss consequent to optic nerve atrophy. In some cases, LHON is associated with heterogeneous neurological extraocular manifestations and is referred to as "Leber plus disease"; rarely it is associated with a multiple sclerosis (MS)-like syndrome known as Harding disease, but no pediatric extraocular acute spinal onset is reported.

Case Presentation: We describe the case of a 5-year-old girl carrying the G3460A mtDNA mutation who was referred to clinical examination for bilateral upper and lower limb weakness with no sign of optic neuropathy. Read More

Department of Ophthalmology.

Purpose Of Review: To review recent advances in the management of acute ocular ischemic events, including: transient monocular vision loss, central and branch retinal artery occlusions, and nonarteritic anterior ischemic optic neuropathy.

Recent Findings: Transient monocular vision loss and acute retinal arterial occlusions require immediate diagnosis and management, with recognition of these events as transient ischemic attack or stroke equivalents, respectively. Patients should undergo an immediate stroke workup in a stroke center, similar to patients with acute cerebral ischemia. Read More

University of Toronto, Department of Ophthalmology and Vision Sciences, 801 Eglinton Ave West Suite 301, Toronto, ON, M5N 1E3, Canada.

Nonarteritic anterior ischemic optic neuropathy (NAION) is a well acknowledged rare complication of chronic hemodialysis in patients with end-stage renal disease (ESRD). We present a unique case of a patient on chronic hemodialysis who presented with an NAION in the right eye, then 3 months later developed an NAION in the left eye followed in 1 month by second NAION episode in the left eye. Every episode of NAION was accompanied by intradialytic hypotension (drop in systolic blood pressure of over 20 mmHg) where visual loss was noticed at the end of the dialysis session. Read More

Acute visual loss and optic disc edema followed by optic atrophy in two cases with deeply buried optic disc drusen: a mimicker of atypical optic neuritis.

Ocular Oftalmologia, Vitória, Brazil.

Background: Sudden visual loss and optic disc edema caused by optic neuritis (ON) is usually followed by significant visual recovery. However, little or no recovery occurs when the loss is caused by atypical ON, especially in patients with neuromyelitis optica (NMO). Optic disc drusen (ODD) is a cause of pseudo optic disc edema and may be a predisposing factor for non-arteritic anterior ischemic optic neuropathy (NAION), thereby mimicking atypical ON. Read More

Risk Factors for Fellow Eye Involvement in Nonarteritic Anterior Ischemic Optic Neuropathy.

J Neuroophthalmol 2018 Oct 8. Epub 2018 Oct 8.

Department of Ophthalmology and Vision Science, University of California, Davis, Sacramento, California.

Background: Nonarteritic anterior ischemic optic neuropathy (NAION) is the most common acute optic neuropathy in individuals older than 50 years. Demographic, ocular, and systemic risk factors for NAION have been identified, and we sought to determine which, if any, of these factors also increase risk of NAION in the fellow eye.

Methods: We performed a retrospective chart review of patients with "ischemic optic neuropathy" (based on International Classification of Disease [ICD] codes) seen at a single eye center between 2007 and 2017. Read More

A Small Molecule TrkB Neurotrophin Receptor Partial Agonist as Possible Treatment for Experimental Nonarteritic Anterior Ischemic Optic Neuropathy.

Curr Eye Res 2018 Dec 1;43(12):1489-1499. Epub 2018 Oct 1.

a Departments of Ophthalmology , Stanford University School of Medicine , Stanford , CA , USA.

Purpose: Brain-derived neurotrophic factor (BDNF) and activation of its high affinity receptor tropomyosin kinase (Trk) B promote retinal ganglion cells (RGCs) survival following injury. In this study, we tested the effects of LM22A-4, a small molecule TrkB receptor-specific partial agonist, on RGC survival in vitro and in experimental nonarteritic anterior ischemic optic neuropathy (AION), the most common acute optic neuropathy in those older than 50 years.

Methods: We assessed drug effects on immunopanned, cultured RGCs and calculated RGC survival and assessed TrkB receptor activation by mitogen-activated protein (MAP) kinase translocation. Read More

Could Platelet Indices and Neutrophil to Lymphocyte Ratio Be New Biomarkers for Differentiation of Arteritic Anterior Ischemic Neuropathy from Non-Arteritic Type?

Neuroophthalmology 2018 Oct 9;42(5):287-294. Epub 2018 Jan 9.

Ankara Ulucanlar Eye Training and Research Hospital, Ankara, Turkey.

The aim of this study was to assess the possible relationship between AAION (arteritic anterior ischemic optic neuropathy) and NAION (non-arteritic anterior ischemic optic neuropathy) with blood platelet parameters and NLR (neutrophil-to-lymphocyte ratio). The medical records of 12 patients with AAION, 33 patients with NAION, and 35 healthy subjects were examined. MPV, PDW, and PCT values showed marked elevation in AAION and NAION groups compared with control group. Read More

Optic nerve head morphology in primary open-angle glaucoma and nonarteritic anterior ischaemic optic neuropathy measured with spectral domain optical coherence tomography.

Acta Ophthalmol 2018 Dec 21;96(8):e1018-e1024. Epub 2018 Sep 21.

Department of Ophthalmology and Optometry, Medical University Vienna, Vienna, Austria.

Purpose: Optic nerve head (ONH) parameters as well as circumpapillary retinal nerve fibre layer (RNFL) thickness values measured with two different spectral domain optical coherence tomography (SD-OCT) machines (Spectralis and Cirrus OCT) have been compared between two patient groups, primary open-angle glaucoma (POAG), nonarteritic anterior ischaemic optic neuropathy (NAION) and healthy controls.

Three-Dimensional High-Resolution Black-Blood Magnetic Resonance Imaging for Detection of Arteritic Anterior Ischemic Optic Neuropathy in Patients With Giant Cell Arteritis.

Invest Radiol 2018 Nov;53(11):698-704

Radiologisches Zentrum Rosenheim, Rosenheim, Germany.

Objectives: Arteritic anterior ischemic optic neuropathy (A-AION) caused by inflammatory occlusion of the posterior ciliary arteries is the most common reason for irreversible vision loss in patients with giant cell arteritis. Atypical clinical presentation and negative funduscopy can delay systemic high-dose corticosteroid therapy to prevent impending permanent blindness and involvement of the contralateral eye.The purpose of this study was to assess the diagnostic accuracy of 3-dimensional (3D) high-resolution T1-weighted black-blood magnetic resonance imaging (T1-BB-MRI) for the detection of posterior ciliary artery involvement in patients with giant cell arteritis and funduscopic A-AION.
