(3) Obtain the Transverse View:

Place the probe lightly on the gel covering the patient’s eye with the probe indicator pointed towards the patient’s right to obtain a transverse view.

(4) Identify the Following Structures

•Eyelid
•Anterior Chamber
•Lens
•Iris
•Vitreous Body
•Retina
•Optic Nerve
•*Make sure to tilt/fan through the entire eye

(5) Obtain TheSagittal View

Next, turn the probe 90° clockwise so the indicator points superiorly towards the patient’s head to obtain a sagittal view. Identify the same structures you found in the transverse view.

(6) Assess extraocular Movements

Evaluate for extraocular movements. This is important when patients have severe periorbital edema from facial trauma.

(7) Obtain Optic Nerve Sheath Diameter (ONSD)

Measure 3 mm (.3cm) posterior to where the optic nerve sheath attaches to the retina. This is the location where you will use to measure your optic nerve sheath diameter.

(9) There are three types of Retinal Detachments:

Rhegmatogenous, Traction, and Exudative.

(10) Retinal Detachment: The defining characteristic is that a retinal detachment is tethered to the optic nerve and moves with the optic nerve.

(11) Posterior Vitreous Detachment looks like a thin, hyperechoic membrane lifted off the posterior surface of the globe that is NOT tethered to the optic nerve.

(14) Central Retinal Artery Occlusion: is a rare finding and color Doppler mode can be used to diagnose it with ocular ultrasound. You may find diminished or absent flow of the central retinal artery.

(17) Lens Dislocation: you will see the lens as a bi-convex structure with hyperechoic borders floating posteriorly in the vitreous body.
