AcQUISITION
Place a tegaderm patch over the closed eyelid
Apply large amounts of gel over closed eyelid
Place the probe gently on the gel, without making direct contact with the patient’s eyelid. The indicator is pointed towards the patient’s right
Fan gently through the entire eye
Identify your landmarks
Anterior chamber: anechoic in the near field
Lens: hyperechoic curved line in the near field
Vitreous humor: anechoic fluid filled space
Retina: hyperechoic line
Optic nerve: hypoechoic in the far field
Ask the patient to move their eye left and right - this may allow for pathologic debris to move through the vitreous fluid
Rotate the probe 90 degrees so that the probe is pointing towards the patient’s head and repeat!
