Neuroprotective effects of low-dose G-CSF plus meloxicam in a rat model of anterior ischemic optic neuropathy.

Sci Rep 2020 Jun 25;10(1):10351. Epub 2020 Jun 25.

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

Non-arteritic anterior ischemic optic neuropathy (NAION) causes a sudden loss of vision and lacks effective treatment. Granulocyte colony-stimulating factor (G-CSF) provides neuroprotection against the experimental optic nerve injuries but also induce leukocytosis upon typical administration. We found synergetic neuroprotective effects of meloxicam and low dose G-CSF without leukocytosis in a rat model of anterior ischemic optic neuropathy (rAION). Read More

Optical coherence tomography angiography in nonarteritic anterior ischemic optic neuropathy due to optic nerve head drusen.

Neurol Sci 2020 Jun 1. Epub 2020 Jun 1.

Department of Neurosciences, Reproductive Sciences and Dentistry, University of Naples Federico II, Naples, Italy.

Optic nerve head drusen (ONHD) are typically benign hyaline and calcified concretions located within the optic nerve. Initially asymptomatic, they can increase slowly in size and number over time, and they can cause mechanical stress at the axons of the optic nerve and progressively lead to a loss of the visual field and papillary vascular changes. Here, we reported a rare case of a young patient with bilateral ONHD complicated by a nonarteritic anterior ischemic optic neuropathy (NAION) in the right eye. Read More

Serviço de Reumatologia e Doenças Ósseas Metabólicas, Hospital de Santa Maria, CHULN, Centro Académico de Medicina de Lisboa, Lisbon, Portugal.

Giant cell arteritis (GCA) is a granulomatous vasculitis involving large- and middle-sized arteries, with a predilection for cranial arteries. In this paper, we aim to describe a case of a biopsy- and ultrasound-proven GCA, presenting with anterior ischemic optic neuropathy (AION) and normal CRP and ESR at diagnosis and during follow-up, and to review the literature on GCA cases with low inflammatory markers, with a particular focus on the presence of eye involvement. Both CRP and ESR are important in the diagnosis of GCA; occurrence of this disease with normal acute phase reactants is unusual but does not rule out the diagnosis. Read More

Optic disc drusen: a systematic review : Up-to-date and future perspective.

Int Ophthalmol 2020 May 7. Epub 2020 May 7.

Department of Biomedical Science, Humanitas University, 20090, Pieve Emanuele, Milano, Italy.

Background: Optic disc drusen (ODD) are acellular deposits in the prelaminar optic nerve head. The most accredited theory is that they are secondary to abnormalities in axonal metabolism and degeneration, but the pathogenesis is not clear to date.

Clinical Manifestation: Although ODD are often considered a benign condition, the great majority of patients with ODD show visual field defects and are at higher risk for developing anterior ischemic optic neuropathy. Read More

Prevalence of Optic Disc Drusen in Young Patients With Nonarteritic Anterior Ischemic Optic Neuropathy: A 10-Year Retrospective Study.

J Neuroophthalmol 2020 Apr 30. Epub 2020 Apr 30.

Department of Clinical Neurological Sciences (Neurology) (JAF), Western University, London, Canada; Department of Ophthalmology (JAF), Western University, London, Canada; and Department of Ophthalmology (LLR, LM, SH), Rigshospitalet, University of Copenhagen, Glostrup, Denmark.

Background: Nonarteritic anterior ischemic optic neuropathy (NAION) in young patients (age ≤50) accounts for a minority of all cases of NAION and is more highly associated with crowding of the optic nerves and bilateral involvement than NAION in older patients. Optic disc drusen (ODD) are likewise associated with crowded optic nerves and are located in the prelaminar optic nerve head where they could contribute to NAION pathogenesis. The purpose of this study was to determine the prevalence of ODD in the eyes of young NAION patients using modern imaging methods and to compare it to the baseline 1. Read More

Shock-induced anterior ischemic optic neuropathy (SIAION) is a known type of optic neuropathy in patients who experienced shock related to different etiologies such as anemia and severe intradialytic hypotension like in our patient. Nonarteritic anterior ischemic optic neuropathy (NAION) is the most common acute unilateral known type of optic neuropathy in older patients with vasculopathic risk factors such as hypertension, diabetes mellitus, and obstructive sleep apnea. Although SIAION and NAION are similar optic neuropathies due to ischemia and, in particular, hypotension, they may have different pathogenic mechanisms (e. Read More

Automatic detection of rare pathologies in fundus photographs using few-shot learning.

Med Image Anal 2020 04 28;61:101660. Epub 2020 Jan 28.

Univ Bretagne Occidentale, Brest, F-29200, France; Inserm, UMR 1101, Brest, F-29200, France; Service d'Ophtalmologie, CHRU Brest, Brest, F-29200, France.

In the last decades, large datasets of fundus photographs have been collected in diabetic retinopathy (DR) screening networks. Through deep learning, these datasets were used to train automatic detectors for DR and a few other frequent pathologies, with the goal to automate screening. One challenge limits the adoption of such systems so far: automatic detectors ignore rare conditions that ophthalmologists currently detect, such as papilledema or anterior ischemic optic neuropathy.

Optic Disc Drusen Associated Anterior Ischemic Optic Neuropathy: Prevalence of Comorbidities and Vascular Risk Factors.

J Neuroophthalmol 2020 Jan 16. Epub 2020 Jan 16.

Department of Ophthalmology, Rigshospitalet, University of Copenhagen, Glostrup, Denmark.

Background: Nonarteritic anterior ischemic optic neuropathy (NA-AION) associated with optic disc drusen (ODD) is termed ODD-AION, where NA-AION with no evidence of ODD is simply termed NA-AION. Patients with ODD-AION have been found to be younger than those with NA-AION but with similar vascular risk factors. This study compares the known risk factors for NA-AION between a group with ODD-AION and a similarly aged group with NA-AION. Read More
