Morning Report: Ocular Ultrasound

Here’s Dr. Brevil with today’s Morning Report!

Ocular Ultrasound

• Since the anterior and posterior chambers of the eye contain vitreous fluid, the eye is an ideal acoustic window for ultrasound imaging
• Normal Anatomy: Iris separates lens and anterior chamber

Retinal Detachment

• Atraumatic RD in 1/10,000
• Presence of unilateral floaters
• Asymptomatic cases in approximately 6% of autopsies
• Appears as hyperechoic undulating structure in posterior to lateral globe
• Can be associated with vitreous hemorrhage

Vitreous Hemorrhage

• Can present as unilateral vision loss
• Can appear differently depending on age and severity
• Echogenic material in posterior chamber

Increased ICP

• Measure 3mm posterior to the globe
• Measure the diameter x2 and take the average
• Less than 5mm is excellent in ruling out increased ICP
• Sensitivity of close to 100%, specificity of close to 63%
• NPV of close to 100%
• Might be an indication to call neurosurg to join trauma surg in the OR for an unstable patient.
