Purpose:
To discuss the practical utility of ocular ultrasound in central retinal artery occlusion.
Methods:
Ocular ultrasound was obtained in four patients with central retinal artery occlusion using a 20 MHz Annular Array Probe of the ABSolu (Quantel Medical, Rockwall, TX) ultrasound machine.
Results:
The causative embolus occluding the central retinal artery was detected on ocular ultrasound imaging in four patients with central retinal artery occlusion.
Conclusion:
Ocular ultrasound, including newer generation, higher frequency ultrasound probes, aids in the detection of the "retrobulbar spot sign," a finding that seems to be related to embolic central retinal artery occlusion. This sign will orient investigations toward finding an embolic source.
