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.
