A UNIQUE CASE OF ACUTE MACULAR NEURORETINOPATHY ASSOCIATED WITH COTTON WOOL SPOTS AND INTRARETINAL FLUID.

Purpose: To discuss the clinical findings in a unique case of acute macular neuroretinopathy with a focus on the pathophysiology of this rare entity.

Methods: The patient's clinical course was documented with color fundus photography and spectral domain ocular coherence tomography registered to infrared reflectance imaging. The visual field was assessed using the Amsler grid testing and Humphrey visual field 24-2.

Chordoma of the anterior cranial fossa and ethmoids with orbital involvement.

Purpose: To report a case of orbital chordoma, emphasizing the clinical, operative, and histopathologic findings, and to review similar English-language reports.

Methods: This is a single case report with histopathologic correlation. Search of the English-language literature and review of referenced citations was performed.

Intravitreal bevacizumab for the treatment of choroidal neovascularization secondary to pseudotumor cerebri.

Background: In pseudotumor cerebri (PTC), elevated intracranial pressure (ICP) results in papilledema and, rarely, choroidal neovascularization (CNV). Pseudotumor cerebri-induced CNV often regresses following medical or surgical ICP reduction, but additional treatments, such as photocoagulation, photodynamic therapy, peri-ocular steroid injections and/or subretinal surgery, may be necessary. Anti-angiogenic intravitreal injections have been shown to cause regression of both CNV and optic nerve edema.

Evaluation of a new water treatment for point-of-use household applications to remove microorganisms and arsenic from drinking water.

Contamination of drinking water by microorganisms and arsenic represents a major human health hazard in many parts of the world. An estimated 3.4 million deaths a year are attributable to waterborne diseases.

Bilateral optic nerve sheath enhancement from giant cell arteritis.

An 83-year-old man presented with acute bilateral visual loss to no light perception (NLP) OD and 20/50 OS. His fundus examination showed moderate bilateral pallid disc edema. A sedimentation rate was 60 mm/h.

Chlorination of model drinking water biofilm: implications for growth and organic carbon removal.

The influence of chlorine on biofilm in low organic carbon environments typical of drinking water or industrial process water was examined by comparing biomass and kinetic parameters for biofilm growth in a chlorinated reactor to those in a non-chlorinated control. Mixed-population heterotrophic biofilms were developed in rotating annular reactors under low concentration, carbon-limited conditions (< 2 mg/L as carbon) using three substrate groups (amino acids, carbohydrates and humic substances). Reactors were operated in parallel under identical conditions with the exception that chlorine was added to one reactor at a dose sufficient to maintain a free chlorine residual of 0.
