Prior research has shown that EPs can accurately detect ocular pathology using POCUS. 

A recent retrospective review looked at how ultrasound image gain levels impacted the accuracy of POCUS for detection of retinal detachment, retinal hemorrhage and posterior vitreous detachment.

They included 383 ED patients who received ocular POCUS and ophthalmology consultations. 

Conclusions: The authors found that increasing the gain for ocular POCUS images allowed for increased sensitivity.

Here is an example of a vitreous hemorrhage on ocular POCUS using low gain and high gain.
