Purpose To report the time course of choroidal blood flow (CBF) in a commotio retinae case using laser speckle flowgraphy (LSFG). Observations A 58-year-old Japanese man with complaints of worsening left visual acuity after blunt eye trauma was diagnosed with commotio retinae. A funduscopic examination showed macular opacity, and LSFG results demonstrated CBF impairment in the affected eye.Op...

PURPOSE To report on the anatomical and functional changes to the macula in nine patients suffering from commotio retinae not accompanied by any other types of traumatic retinopathy. METHODS Nine injured eyes with commotio retinae were evaluated soon after ocular trauma with ophthalmic examination, including Spectral-domain optical coherence tomography (SD-OCT). In 12 eyes of 6 patients, Hump...

Sudden cardiac death (SCD) in a young athlete is rare, but catastrophic. Exercise acts as a risk factor for SCD in people with cardiovascular disease. A diversity of cardiovascular disorders including hypertrophic cardiomyopathy, congenital coronary anomalies, arrhythmogenic right ventricular dysplasia, dilated cardiomyopathy, aortic rupture due to Marfan syndrome, myocarditis, valvular disease...

ABSTRACT: When an athlete suffers a sudden cardiac death, particularly while participating in a sport being viewed by thousands of spectators, it is a rare and catastrophic event that generates a great deal of discussion among the general public and medical community. Many cardiovascular conditions can predispose an athlete to such an event. The most common causes of sudden cardiac death in ath...

Regional mechanical and electrophysiological changes accompany most ventricular arrhythmias and, it has been suggested, by mechanoelectric feedback. We hypothesized that an intervention producing regional mechanical dispersion was associated with regional, proarrhythmic electrical dispersion and studied the regional mechanoelectric feedback in the right ventricle (RV) of anesthetized lambs. Ten...

Sudden cardiac death (SCD) in young athletes is a tragic event with devastating effects on the family, athletic team, and the local community. Unfortunately sudden cardiac arrest (SCA) due to ventricular fibrillation (VF) is often the first manifestation of underlying cardiovascular disorders and is associated with high mortality. Sudden death in sport is rare and is usually due to congenital o...

Acute traumatic maculopathy included a spectrum of disorders following blunt ocular trauma, such as pigment epitheliopathy, commotio retina, and choroidal rupture.
