Blunt Ocular Trauma

We present a case of a patient who underwent ultrasound evaluation for potential blunt ocular trauma. She was found to have multiple, freely mobile, scintillating hyperechoic opacities within the vitreous that was diagnosed as asteroid hyalosis, a rare but benign condition easily confused with vitreous hemorrhage, retinal detachment, lens dislocation, or foreign body on ocular ultrasound.

Abstract Point of care ultrasound in the emergency department (ED) is increasingly being used to diagnose time-sensitive, vision-threatening conditions. We present a case of a 64-year-old female who presented to the ED with a three-day history of worsening left eye floaters. Point of care ocular ultrasound demonstrated a posterior chamber containing many echogenic opacities of varying size without acoustic shadowing. Movement of the eye resulted in significant after-movement of these opacities, giving the classic “washing machine” appearance seen with vitreous hemorrhage (VH). Based on these ultrasound findings, the patient was diagnosed with a VH and was referred to ophthalmology. The consulting ophthalmologist ultimately diagnosed the patient with asteroid hyalosis without VH. Asteroid hyalosis is a benign condition of the vitreous resulting in calcium phosphate and lipid deposits that can mimic more serious VH on point of care ultrasound. Knowledge of this mimic is helpful for communication with specialists and for awareness of the potential for misdiagnosis with ocular ultrasound.

ABSTRACT Point-of-care ultrasound (POCUS) has become an essential part of the evaluation of vision loss among emergency physicians in the emergency department (ED). It is frequently used to evaluate for vitreous hemorrhage, foreign bodies, retinal detachment, optic neuritis and posterior vitreous detachment; however, it can also be used to evaluate for a central retinal artery occlusion (CRAO). A POCUS can reveal a hyperechoic density in the optic nerve sheath just proximal to the retinal surface, and this is referred to as a retrobulbar ‘spot sign’ (RBSS). We present the case of an 88-year-old male that presented to our community ED with a painless loss of vision to his right eye. A POCUS revealed an RBSS of the central retinal artery and he was subsequently diagnosed with a CRAO. At his 1-month follow-up, he has regained light perception and 15% of his vision, however, remains with significant visual impairment.

Insight Into

Background: Lung Ultrasound Evaluation (LUS) is usefully applied in the Emergency Department (ED) to patients with suspected or confirmed COVID-19. Diaphragmatic Ultrasound (DUS) may provide additional insight into ventilatory function. This proof-of-concept study aimed to evaluate the feasibility of LUS and DUS in a third level ED during the COVID-19 pandemic. Methods: Adult patients presenting with COVID-19 symptoms were eligible. After the physical examination, both LUS and DUS (i.e., diaphragmatic motion and thickness) were performed. All patients were followed after 30 days to determine their need for ventilation, admission, and/or a new ED evaluation after discharge. The diagnostic accuracies of diaphragm measurements in assessing the risk of the 30-day outcome were calculated as well as the measurements’ usefulness. Bland–Altman plots were used for comparing bedside and off-line diaphragm measurements. Results: 118 patients were enrolled. Median thickness and motion were 1.7 mm (iqr 0.4) and 1.8 cm (iqr 0.7), respectively, with a mean difference of 0.009 mm (95% CI −0.037–0.056 mm) and −0.051 cm (95% CI −0.108–0.006 cm), respectively. The 30-day outcome was associated with an increase in thickness (OR 5.84, 95% CI 0.96–35.4), and a lower motion (OR 0.49, 95% CI 0.2–1.21). Conclusion: DUS seemed to be feasible and reliable in the ED in a population of patients presenting with symptoms related to COVID-19 infection.

Objectives: This study aimed to use gastric point of care ultrasound (POCUS) to estimate the prevalence of an “empty stomach” among patients undergoing procedural sedation and analgesia (PSA) in the emergency department (ED) after observing the requisite fasting time at home. Methods: A prospective observational study was conducted with children with facial lacerations who made a scheduled revisit to the ED after completion of the recommended fasting time. Their stomach contents were assessed with a sagittal view of the gastric antrum by POCUS in the right lateral decubitus position. The characteristics of gastric contents were described as empty, solid, and liquid with an estimated gastric volume. “Empty stomach” was defined as a collapsed gastric antrum or calculated a gastric fluid volume of less than or equal to 1.25 mL/kg on POCUS. Results: Gastric POCUS was performed in 125 patients, and the final analysis included 122 patients. For 95 patients who had followed the recommended fasting time, the median fasting time was 7 hours for solids and 6 hours for liquids, and 78 (82%) patients had an empty stomach. Conversely, seven of 27 patients (26%) who did not have an adequate fasting time had an empty stomach. The optimal cut-off value of fasting time to predict an empty stomach was 6.5 hours based on a receiver operating characteristic (ROC) analysis (sensitivity = 0.767, specificity = 0.811). Conclusions: Most scheduled revisiting children had an “empty stomach” at the time of sedation after the recommended fasting. However, providers should be aware that one in five children still had stomach residue, although they had more than 6 hours of fasting.
