BACKGROUND: Sarcoidosis, a multisystem, granulomatous disorder, sometimes manifests with a neuro-ophthalmic subtype. The latter can pose a diagnostic challenge, especially when ocular symptoms appear before systemic involvement, as the clinical picture then can be non-specific and systemic laboratory and standard imaging investigations can be negative. FINDINGS: A 71-year-old woman presented with a 4-month history of sudden-onset visual loss in the left eye. Slit lamp examination revealed anterior chamber cells, iris, and angle neovascularization...

We report a case of an 18-year-old woman with systemic antibiotic anaphylaxis who presented anasarca and bilateral visual loss two weeks after the intravenous use of pazufloxacin. Ancillary fundus tests revealed bilateral cotton-wool spots, Purtscher flecken, edema, and retinal arteriolar occlusion around the optic disc. After pulse corticosteroid, administration of anti-anaphylactic agent, and general support therapy for one month, the patient showed a favorable change, with the symptoms lessened or free systemically, except the continuous aggravation of fundus ischemic change...

We evaluated thirteen eyes of twelve patients diagnosed clinically and serologically with Toxocara optic neuropathy. Eleven patients had unilateral involvement and one patient had bilateral optic neuropathy. Eight patients (66.7%) had a possible infection source to Toxocara. Six patients (50%) had painless acute optic neuropathy. Ten eyes had asymmetric, sectorial optic disc edema with peripapillary infiltration and three eyes had diffuse optic disc edema. Eosinophilia was noted in five patients (41.7%) and optic nerve enhancement was observed in eight of eleven eyes (72...

BACKGROUND: Optic neuritis in children is an uncommon disorder which usually occurs after a viral illness or vaccination and, less frequently, occurs as a manifestation of a demyelinating disorder. Pediatric optic neuritis usually is bilateral and presents with optic disc edema, recovers rapidly with steroid therapy, and generally has low conversion rate to multiple sclerosis or neuromyelitis optica spectrum disorder. We report the clinical features and treatment outcomes of pediatric optic neuritis in Indian population, for which little data are available...

Interesting novel and somewhat perplexing physiologic and pathologic neuro-ocular findings have been documented in astronauts during and after long duration space flight (LDSF). These findings collectively have been termed the "space flight-associated neuro-ocular syndrome" (SANS). The National Aeronautics and Space Administration (NASA) in the United States has meticulously and prospectively documented the clinical, ultrasound, optical coherence tomography imaging, and radiographic findings of SANS including unilateral and bilateral optic disc edema, globe flattening, choroidal and retinal folds, hyperopic refractive error shifts, and nerve fiber layer infarcts (i...

OBJECTIVE Tumor-related edema of the optic tract (EOT) corresponds to a preferential posterior distribution of peritumoral edema along the white matter tract of the visual system. To date, the consequences of EOT have never been evaluated specifically in the pediatric population. In this study, the authors attempted to identify clinical and radiological features associated with the development of EOT and the specific influence of this edema on visual function. METHODS A retrospective review was performed of data collected from patients younger than 18 years who underwent surgery for a tumor in the sellar region at the authors' institution between January 2005 and January 2016...

Importance: Autoantibodies to aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) are recently established biomarkers of autoimmune optic neuritis whose frequency and accompanying phenotype, especially for MOG-IgG, are still being characterized. The Optic Neuritis Treatment Trial (ONTT) was a well-known randomized clinical trial in optic neuritis; therefore, knowledge of the serostatus and accompanying phenotype of these patients would be useful to determine the frequency of these antibodies in patients presenting with typical monocular optic neuritis and their outcomes...

Optic disc edema may be caused by a number of conditions. A commonly ignored but important aspect is the presence of "infiltration" of disc; that may closely mimic disc edema. Disc edema, optic nerve dysfunction and a normal appearing disc in any combination may occur in infiltrative optic neuropathies. Identifying disc infiltration can aid in diagnosis of many sinister pathologies even in the absence of other specific clinical features. We describe two patients presenting with optic nerve dysfunction and infiltrated disc appearance, which on investigations were found to have underlying malignancies thereby underscoring the importance of detecting infiltrative optic neurpathies...

Differentiating optic disc edema (ODE) from pseudo optic disc edema (PODE) continues to pose a diagnostic dilemma. Current report highlights the role of multicolor imaging (MC) in differentiating ODE from PODE. Composite multicolor images of the disc in ODE show greenish hyperreflectance that extends beyond the optic disc margins with irregular blurry margins and obscured disc vasculature whereas PODE shows a greenish hyperreflectance with clear and distinct margins and well delineated disc vasculature. MC imaging adds to the present armamentarium of imaging modalities obviating needless neurological evaluation mandatory in a case of true disc edema...

Idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) is a rare syndrome affecting the retinal and optic disc vasculature. Diffuse retinal ischemia, macular edema, and neovascularization may lead to bilateral vision loss. The authors report a case of a 36-year-old woman presenting with branch retinal artery occlusion (BRAO) in her right eye who was subsequently diagnosed with IRVAN syndrome. She was treated with panretinal photocoagulation for peripheral retinal ischemia and pars plana vitrectomy for vitreous hemorrhage...

BACKGROUND: Making an accurate diagnosis of optic disc drusen (ODD) is important as part of the work-up for possible life-threatening optic disc edema. It also is important to follow the slowly progressive visual field defects many patients with ODD experience. The introduction of enhanced depth imaging optical coherence tomography (EDI-OCT) has improved the visualization of more deeply buried ODD. There is, however, no consensus regarding the diagnosis of ODD using OCT. The purpose of this study was to develop a consensus recommendation for diagnosing ODD using OCT...
