Point of care ultrasound in the emergency department (ED) is increasinglybeing used to diagnose time-sensitive, vision-threatening conditions. We present acase of a 64-year-old female who presented to the ED with a three-day history ofworsening left eye floaters. Point of care ocular ultrasound demonstrated aposterior chamber containing many echogenic opacities of varying size withoutacoustic shadowing. Movement of the eye resulted in significant after-movement ofthese opacities, giving the classic “washing machine” appearance seen withvitreous hemorrhage (VH). Based on these ultrasound findings, the patient wasdiagnosed with a VH and was referred to ophthalmology. The consultingophthalmologist ultimately diagnosed the patient with asteroid hyalosis withoutVH. Asteroid hyalosis is a benign condition of the vitreous resulting in calciumphosphate and lipid deposits that can mimic more serious VH on point of careultrasound. Knowledge of this mimic is helpful for communication with specialistsand for awareness of the potential for misdiagnosis with ocularultrasound.
