Non-Arteritic Anterior Ischemic Optic Neuropathy Following COVID-19 Vaccination.

Vaccines (Basel) 2022 Jun 10;10(6). Epub 2022 Jun 10.

Department of Ophthalmology, Chang Gung Memorial Hospital, Chiayi 61363, Taiwan.

People are advised to receive a vaccine booster as the Delta and Omicron variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerge, but various adverse ocular reactions after vaccination have been reported. NAION following COVID-19 vaccination appears extremely rarely. Here, we report a case of a 61-year-old female with sudden painless blurred vision developing NAION after receiving ChAdOx1 nCoV-19 (AstraZeneca) vaccination and provide an in-depth explanation of the possible mechanisms regarding the hypercoagulable state after vaccination.

Vision loss in giant cell arteritis: case-based review.

Rheumatol Int 2022 Jun 21. Epub 2022 Jun 21.

Department of Rheumatology, Patras University Hospital, University of Patras Medical School, Patras, Greece.

Prompt initiation of pulse glucocorticoid treatment is recommended in case of visual symptoms and suspected or proven giant cell arteritis (GCA). Pulse treatment in most cases prevents involvement of an initially unaffected fellow eye. We present the case of a biopsy-proven GCA in a 79-year-old man, complicated by sequential bilateral blindness. Read More

Upregulation of retinal VEGF and connexin 43 in murine nonarteritic anterior ischemic optic neuropathy (NAION) induced with 577 nm laser.

Exp Eye Res 2022 Jun 9:109139. Epub 2022 Jun 9.

Department of Ophthalmology, Stanford University School of Medicine, Stanford, CA, 94303, USA; Department of Neurology, Stanford University School of Medicine, Stanford, CA, 94304, USA. Electronic address:

Nonarteritic anterior ischemic optic neuropathy (NAION) is a common acute optic neuropathy and cause of irreversible vision loss in those older than 50 years of age. There is currently no effective treatment for NAION and yet the biological mechanisms leading to neuronal loss are not fully understood. Glial cells activation and intercommunication mediated by molecules such as gap junction protein Connexin 43 (Cx43) is thought to modulate neuronal fate in central nervous system disorders.

A peculiar case of syphilis infection: The great imitator is on the rise.

IDCases 2022 18;28:e01521. Epub 2022 May 18.

Department of Internal Medicine, Groene Hart Ziekenhuis, Gouda, The Netherlands.

The incidence of syphilis is on the rise worldwide and can pose many diagnostic and therapeutic difficulties for doctors. Given the wide variety of presenting symptoms, syphilis is also known as the great imitator, which in turn frequently leads to a pronounced diagnostic- and therapeutic delay for patients. Here we present a case report of syphilitic uveitis and papillitis accompanied by acute vision loss, a rare presentation of a tertiary syphilis infection that clinically mimicked a giant cell arteritis (GCA) or arteritic anterior ischemic optic neuropathy (AAION).

[Optical coherence tomography in the differential diagnostics of important neuro-ophthalmological disease patterns].

Nervenarzt 2022 Jun 25;93(6):629-642. Epub 2022 May 25.

Universitäts-Augenklinik, Department für Augenheilkunde, Universitätsklinikum Tübingen, Elfriede-Aulhorn-Straße 7, 72076, Tübingen, Deutschland.

There are many disease patterns that are treated jointly by neurologists and ophthalmologists, for which optical coherence tomography (OCT) is of important differential diagnostic significance. In this context neurologists are mainly confronted by two patient collectives: patients with an acute ischemic event, who present with an acute but painless monocular visual deterioration (for central retinal artery occlusion) or with a monocular visual field defect (for arterial branch occlusion or anterior ischemic optic neuropathy). The second collective is patients without ophthalmological symptoms but with conspicuous optic nerve findings (papilledema or optic disc drusen). Read More

Long term therapeutic effects of icariin-loaded PLGA microspheres in an experimental model of optic nerve ischemia via modulation of CEBP-β/G-CSF/noncanonical NF-κB axis.

Bioeng Transl Med 2022 May 7;7(2):e10289. Epub 2022 Jan 7.

Institute of Eye Research Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation Hualien Taiwan.

An ischemic insult at optic nerve (ON) is followed by detrimental neuroinflammation that results in progressive and long-lasting retinal ganglion cell (RGC) death and vision loss. Icariin was reported to be a safe and effective natural anti-inflammatory drug. Herein, we evaluated the long-term therapeutic effects of a single intravitreal injection of poly(lactide-co-glycolide) PLGA-icariin in a rat model of anterior ischemic optic neuropathy (rAION).

A Potential Role of Acute Choroidal Expansion in Nonarteritic Anterior Ischemic Optic Neuropathy.

Invest Ophthalmol Vis Sci 2022 04;63(4):23

Department of Ophthalmology, University of Alabama at Birmingham, Birmingham, Alabama, United States.

Purpose: Nonarteritic anterior ischemic optic neuropathy (NAION) has been associated with a thickened choroid at the optic nerve head (ONH). Here, we use computational modeling to better understand how choroidal expansion and choroidal geometry influence tissue deformation within the ONH relative to intraocular pressure (IOP) and intracranial pressure (ICP) effects.

Methods: Using a model of the posterior eye that included the sclera, peripapillary sclera, annular ring, pia mater, dura mater, neural tissues, Bruch's membrane, choroid, and lamina cribrosa, we examined how varying material properties of ocular tissues influenced ONH deformations under physiological and supra-physiological, or "pathological," conditions.

Sleep and eye disease: A review.

Clin Exp Ophthalmol 2022 04 16;50(3):334-344. Epub 2022 Mar 16.

Centre for Ophthalmology and Visual Science (incorporating the Lions Eye Institute), University of Western Australia, Perth, Western Australia, Australia.

There is a growing body of literature on the effects of sleep disorders, in particular obstructive sleep apnoea (OSA), on ocular health, with consistent evidence of an increased risk of floppy eyelid syndrome, non-arteritic anterior ischaemic optic neuropathy, diabetic macular oedema, and other retinal vasculature changes in individuals with OSA. However, reports on OSA's associations with glaucoma, papilloedema, diabetic retinopathy, central serous chorioretinopathy, and keratoconus have been conflicting, while links between OSA and age-related macular degeneration have only been described fairly recently. Despite numerous suggestions that OSA treatment may reduce risk of these eye diseases, well-designed studies to support these claims are lacking. Read More
