Purpose: To describe a unilateral ocular paraneoplastic syndrome in pineal germinoma. Observations: A 24-year-old male presented with diplopia, excessive thirst, and frequent urination. Cranial MRI showed a mass in pineal gland. Dorsal midbrain syndrome signs were present. Examination showed optic disc edema and segmental retinal periphlebitis in right and normal fundus in left eye. Rheumatologic work-up was negative. Brain biopsy confirmed pineal germinoma. Retinal findings were attributed to paraneoplastic syndrome...

On Earth, tissue weight generates compressive forces that press on body structures and act on the walls of vessels throughout the body. In microgravity tissues no longer have any weight and tissue compressive forces are lost, suggesting individuals who weigh more may show greater effects from microgravity exposure. One unique effect of long-duration microgravity exposure is the spaceflight-associated neuro-ocular syndrome (SANS) which can present with globe flattening, choroidal folds, optic disc edema, and a hyperopic visual shift...

BACKGROUND: POEMS syndrome is a plasma cell disorder, which clinically manifests from paraneoplastic syndrome: polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma cell disorder, and skin changes. The most common ocular manifestation is optic disc swelling, whereas other ocular manifestations; cystoid macular edema, serous macular detachment, venous sinus thrombosis, infiltrative orbitopathy, uveitis, neovascularization of the disc, peripapillary choroidal neovascularization and optic disc drusen, had also been reported...

PURPOSE: To examine the role of oral steroid therapy in the treatment of nondiabetic cases of acute nonarteritic anterior ischemic optic neuropathy (NAAION). DESIGN: Randomized double-blind clinical trial. PARTICIPANTS: Thirty-eight patients with acute nondiabetic NAAION divided into 2 arms of 19 patients each. One arm constituted the cases and the other constituted the controls. METHODS: Cases received oral steroid therapy and were designated the steroid group, whereas controls received placebo and were designated the nonsteroid group...

BACKGROUND: Diabetic macular edema (DME) is one of the severe complication of diabetic retinopathy causing severe vision loss and leads to blindness in severe cases if left untreated. OBJECTIVE: To grade the severity of DME in retinal images. METHODS: Firstly, the macular is localized using its anatomical features and the information of the macula location with respect to the optic disc. Secondly, a novel method for the exudates detection is proposed...

Pediatric uveitis differs from adult-onset uveitis and is a topic of special interest because of its diagnostic and therapeutic challenges. Children with uveitis are often asymptomatic and the uveitis is often chronic, persistent, recurrent, and resistant to conventional treatment. Anterior uveitis is the most common type of uveitis in children; the prevalence of intermediate, posterior, and panuveitis varies geographically and among ethnic groups. Regarding etiology, most cases of pediatric uveitis are idiopathic but can be due to systemic inflammatory disorders, infections, or a manifestation of masquerade syndrome...

PURPOSE: To describe a case of microsporidial stromal keratitis with endophthalmitis in an immunocompetent patient. METHODS: Case reportResults: A 58-year-old HIV-negative man presented with stromal keratitis in his right eye. The patient demonstrated subsequent vitritis, multifocal retinitis and arteritis, and macular edema with recurrent vitreous hemorrhage after therapeutic keratoplasty. Numerous microsporidial spores were detected in corneal tissues by modified trichrome stain...

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...

BACKGROUND: Chorioretinitis is an unusual form of varicella zoster virus (VZV)-associated uveitis, and no report has described VZV-associated chorioretinitis using serial optical coherence tomography (OCT) images obtained during the course of resolution. CASE PRESENTATION: A 61-year-old woman presented with acute, unilateral vision loss in her right eye. Her visual acuity was count fingers in the right eye and 16/20 in the left eye, and she exhibited skin vesicles on her right forehead...
