Malaria retinopathy and cerebellitis in a 9-year-old boy in the United States.

Malarial retinopathy is characterized by retinal whitening, vessel change, and hemorrhages usually associated with a white center. We present the case of a 9-year-old boy who presented with a systemic Plasmodium falciparum infection, hemorrhagic cerebellitis and malarial retinopathy characterized by "fire flare" hemorrhages (scleral icterus with subconjunctival hemorrhages), Roth spot-like hemorrhages, and subhyaloid hemorrhage. To our knowledge, this is the first reported case of hemorrhagic cerebellitis secondary to P.

Transarterial Onyx Embolization of an Orbital Solitary Fibrous Tumor.

Solitary fibrous tumor (SFT) is an uncommon mesenchymal neoplasm sometimes found in the orbit. We report a case of an aggressive orbital SFT with enlarged feeding vessels that was successfully resected immediately after transarterial embolization with Onyx (ethylene vinyl alcohol copolymer). To our knowledge, this is the first report showing the histopathology of Onyx embolization material in an orbital SFT.

Visual hallucinations (Charles Bonnet syndrome) associated with neurosarcoidosis.

The Charles Bonnet syndrome (CBS) refers to lucid and complex visual hallucinations in cognitively normal patients with acquired vision loss. It can be associated with any type of vision loss including that related to macular degeneration, corneal disease, diabetic retinopathy, and occipital infarct. Neurosarcoidosis, a multi-systemic inflammatory granulomatous disease affecting both the central and peripheral nervous systems, is rarely associated with CBS.

Neuroimaging in ophthalmology.

In the past three decades, there have been countless advances in imaging modalities that have revolutionized evaluation, management, and treatment of neuro-ophthalmic disorders. Non-invasive approaches for early detection and monitoring of treatments have decreased morbidity and mortality. Understanding of basic methods of imaging techniques and choice of imaging modalities in cases encountered in neuro-ophthalmology clinic is critical for proper evaluation of patients.

Late-onset Leber hereditary optic neuropathy.

Background: While Leber hereditary optic neuropathy typically causes bilateral visual loss in the second through fourth decades, we highlight visual loss from Leber hereditary optic neuropathy in older patients to characterize the clinical features of this cohort.

Design: Retrospective case series.

Participants: Patients seen between January 2003 and July 2012 at Baylor College of Medicine and between April 2010 and July 2012 at The Methodist Hospital in Houston, Texas.

A pox upon your house.

Herpes zoster ophthalmicus (HZO) is a common viral infectious disorder affecting the ophthalmic division of the trigeminal nerve. A small subset of HZO patients present with the ophthalmic symptoms, but without an accompanied rash, a condition described as Herpes zoster sine herpete. Although HZO is well known to be associated with other central nervous system abnormalities, encephalitis and cerebral infarction are atypical and uncommon.

Sub-tenon atracurium injection in rabbit eyes;a histopathologic study.

Purpose: To evaluate early and late histopathologic changes following posterior sub-Tenon injection of atracurium in the rabbit eye.

Methods: This study was performed on 39 healthy white New Zealand rabbits which received sub-Tenon injection of 0.05-0.
