BACKGROUND: Ocular emergencies account for 2-3% of all emergency department (ED) visits. Sonographic evaluation of the eye offers a very useful diagnostic tool in the ED. In the ED setting, ocular ultrasound could identify a retinal detachment, or a massive vitreous hemorrhage, and the training for emergency medicine practitioners is quite easy. CASE REPORT: An 84-year-old woman presented to our ED with a painless acute vision loss in her right eye. Immediate bedside emergency ocular ultrasound was performed, and it showed a retrobulbar hyperechoic material, suggestive of an embolus within the central retinal artery...

Bedside sonographic measurement of optic nerve sheath diameter can aid in the diagnosis of elevated intracranial pressure in the emergency department. This case report describes a 21-year-old female presenting with 4 months of mild headache and 2 weeks of recurrent, transient binocular vision loss. Though limited by patient discomfort, fundoscopic examination suggested the presence of blurred optic disc margins. Bedside ocular ultrasound (BOUS) revealed wide optic nerve sheath diameters and bulging optic discs bilaterally...

INTRODUCTION: Elevated intracranial pressure (ICP) is a major and potentially lethal disorder in patients admitted to the emergency department (ED). Several methods are being used to investigate for elevated ICP. Here we assessed and compared the diagnostic accuracy of two existing tools of ophthalmoscopy and optic nerve ultrasonography in detection of elevated ICP. METHODS: 131 participants with probable elevation of ICP referred to the emergency department of Al-Zahra Hospital, Isfahan, Iran, from 2012 to 2014, were enrolled...

Ocular injuries are common in the emergency department, and they are the most frequent cause of noncongenital monocular blindness in children and adults. This review provides evidence-based recommendations for the diagnosis, treatment, and disposition of patients with all types of ocular trauma, including pain management, the use of antibiotics, cycloplegics, steroids, antifibrinolytics, and patching. Bedside ocular ultrasound has profoundly expanded diagnostic capability, particularly for the multiply injured patient, and routine management and disposition of patients with corneal abrasions has evolved significantly as well...

Bilateral retinal detachments are a rare complication of preeclampsia. We present a case report of a patient with an unknown pregnancy who presented with acute bilateral vision loss and elevated blood pressure. Point-of-care ocular ultrasound revealed bilateral retinal detachments. She was diagnosed with severe preeclampsia and taken for an urgent caesarean section with the delivery of a 26-week-old infant.

Diagnosis and measuring the level of increase in intracranial pressure (ICP) is critical, especially for the management of trauma patients in the emergency department and intensive care unit. However, measurements are operator-dependent as in all of the sonographic diagnoses. The aim of this study is to assess the operator variations in the measurement of optic nerve sheath diameter (ONSD). There were four emergency medicine specialists involved in the study. Each had at least 1 year of experience of ultrasound scans and performed at least 25 prior ocular scans examining the ONSD...

UNLABELLED: CNS Tuberculosis can manifest as meningitis, arachnoiditis and a tuberculoma. The rupture of a tubercle into the subarachnoid space leads to Tuberculosis Meningitis (TBME); the resulting hypersensitivity reaction can lead to an elevation of the intracranial pressure and hydrocephalus. While bedside optic nerve sheath diameter (ONSD) ultrasonography (USG) can be a sensitive screening test for elevated intracranial pressure in adult head injury, little is known regarding ONSD measurements in Tuberculosis Meningitis...

Point-of-care ocular ultrasound has been used to detect papilledema. In previous studies, investigators have evaluated only optic nerve sheath diameter as a screen for increased intracranial pressure. In this series of 4 children, we demonstrate 2 additional optic nerve abnormalities using point-of-care ocular ultrasound: optic disc elevation and the crescent sign. Assessing the optic nerve for each of these 3 findings may assist the examiner in detecting papilledema.

INTRODUCTION: Point-of-care ocular ultrasound (US) is a valuable tool for the evaluation of traumatic ocular injuries. Conventionally, any maneuver that may increase intraocular pressure (IOP) is relatively contraindicated in the setting of globe rupture. Some authors have cautioned against the use of US in these scenarios because of a theoretical concern that an US examination may cause or exacerbate the extrusion of intraocular contents. This study set out to investigate whether ocular US affects IOP...

BACKGROUND: Ocular trauma and acute loss of vision are high-yield patient presentations that may benefit from the use of bedside ultrasound to aid in the diagnosis of a variety of vision-threatening problems. CASE REPORT: We present a case of bilateral lens dislocation in which the diagnosis of lens dislocation was missed on initial computed tomography of the orbits but detected on bedside ultrasound. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Point-of-care ultrasound can rapidly identify ocular pathology and expedite specialist consultation, and if necessary, transfer to a specialty center for further management...

Increased anterior chamber pressure also known as intraocular pressure can result from conditions such as glaucoma and trauma. The pressure in the anterior chamber is measured using tonometer. Measurement of the intraocular pressure is essential, as it requires immediate medical attention to alleviate pain and to avoid temporary or permanent damage to intraocular structures. Bedside ocular ultrasound (US) has gained popularity in recent years. It has been used to assess intracranial pressure via optic nerve sheath diameter (ONSD) and evaluate retinal detachment, vitreous hemorrhage, or pupillary reflex in a trauma patient...

Idiopathic intracranial hypertension (IIH), also referred to as pseudotumor cerebri, is a condition of raised intracranial pressure (ICP) with unknown etiology. Sonographic measurement of optic nerve sheath diameter (ONSD) has been shown to be a reliable, noninvasive method to characterize elevated ICP in a variety of settings. However, little is known about the immediate response of ONSD to an acute reduction in ICP after lumbar puncture. We describe a case of an emergency department patient with IIH in whom we identified real-time change in ONSD correlated with a decrease in cerebrospinal fluid pressure after a therapeutic lumbar puncture...

INTRODUCTION: Intraocular hemorrhage in patients suffering from aneurysmal subarachnoid hemorrhage is known as Terson's syndrome and is an underestimated but common pathology. We therefore designed a prospective single-blinded study to evaluate the validity of ocular ultrasound compared to the gold standard indirect funduscopy in the diagnosis of Terson's syndrome. MATERIAL AND METHODS: Fifty-two patients (104 eyes in total) suffering from aneurysmal subarachnoid hemorrhage were enrolled in this study...

OBJECTIVE: The purpose of this study was to determine if patients with nontraumatic causes of elevated intracranial pressure (ICP) could be identified by ultrasound measurement of optic nerve sheath diameter (ONSD). It was hypothesized that an ONSD greater than or equal to 5 mm would identify patients with elevated ICP. METHOD: This was a prospective observational trial comparing ONSD with ICP measured by opening pressure manometry on lumbar puncture (LP). The cohort consisted of a convenience sample of adult patients presenting to the emergency department, requiring LP...
