Endogenous endophthalmitis is a very rare but potentially devastating intraocular inflammation resulting from hematogenous dissemination into the eye from a remote focus of infection. We present a case of a 49-year-old Vietnamese gentleman with underlying hypertension and ischemic heart disease who presented with sudden onset bilateral eye blurring of vision for five days associated with fever, chills, and rigors. He started to have a chesty cough with right-sided pleuritic chest pain for three days as well as shortness of breath, which developed one day prior to admission...

BACKGROUND: Artificial intelligence (AI) is increasingly a part of daily life and offers great possibilities to enrich health care. Imaging applications of AI have been mostly developed by large, well-funded companies and currently are inaccessible to the comparatively small market of point-of-care ultrasound (POCUS) programs. Given this absence of commercial solutions, we sought to create and test a do-it-yourself (DIY) deep learning algorithm to classify ultrasound images to enhance the quality assurance work-flow for POCUS programs...

Dear Editor, An 83-year-old woman developed yellow-brownish infiltrates, nodules, and tumors mimicking xanthomas, mostly involving the periorbital and chest area within three months (Figure 1). She had no abnormalities in serum cholesterol or triglycerides levels. A detailed laboratory analysis revealed the presence of mild monoclonal gammopathy with a presence of immunoglobulin G (IgG) kappa light chains; however, according to hematologist consultation, it did not require medical intervention. Imaging assessment and ultrasound examination did not show any specific involvement of internal organs...

A 10-year-old German Warmblood gelding was referred to the Equine Department of the Vetsuisse Faculty, University of Zurich, Switzerland, for an iris mass OD, lethargy, intermittent fever, and coughing. Ophthalmic examination revealed a 7 × 9 mm raised, fleshy, whitish to pinkish, vascularized iris mass at the 2 o`clock position OD. Fundic examination showed multifocal round, brown to black, slightly raised lesions with indistinct margins and a surrounding hyperreflective zone OU. Physical examination revealed a temperature of 39...

PURPOSE: To compare dynamic autoregulation in the middle cerebral artery (MCA) and the ophthalmic artery (OA) after a step decrease in systemic blood pressure. METHODS: Eighteen healthy male young subjects were studied. Ultrasound parameters and systemic blood pressures were recorded in each subject before, during, and after a step decrease in blood pressure. Continuous blood pressure recordings were made with a finger plethysmograph system, and flow velocities in the MCA and the OA were continuously measured with Doppler ultrasound...
