2019年4月29日 · Ultrasound Differential for Painless Vision Changes. Retinal Detachment. Presentation: Acute onset of unilateral floaters and/or pinpoint flashing lights (photopsias) Can have visual loss or visual field cuts; Note: Can be caused by trauma but more commonly occurs spontaneously or secondary to systemic disease (i.e. vasculopathies)

2014年3月11日 · Retinal detachment (RD) will be visualized in normal and often low gain settings. A RD has the appearance of a thick cord that is attached to the back wall of the eye and moves with eye movement. If the RD is large, the flap will be attached firmly to the optic nerve sheath.

Retinal Detachment (RD) A retinal detachment is defined by a separation of the sensory retina from the underlying retinal pigment epithelium. This cuts off the blood supply to the rods and cones in the eye and can cause permanent vision loss.

2009年5月1日 · Understand the normal ultrasound anatomy of the eye, specifically the location of the retina. Know which probe is needed for ultrasound scans of the eye, and the method to accurately and safely perform the exam. Visualize an example of a …

One of the most important use of ocular ultrasound is to rule out a retinal detachment (RD) which may require vitreoretinal surgical intervention. Differentiation of a posterior vitreous detachment (PVD) from RD is important.

2024年2月1日 · Convection motion can be seen as movement within a lesion and typically indicates stagnant blood or cholesterol debris such as in a choroi­dal effusion or a Coats disease–related serous retinal detachment.

2018年3月19日 · Using the Ultrasound for Detection of Retinal Detachment. On ultrasound, RD appears as a hyperechoic rippled (or undulating) line/membrane in the posterior to lateral globe.

2023年7月24日 · Retinal detachment is visualized on ultrasound as a mobile hyperechoic membrane or flap, often described as having serpentine motion with eye movement. Retinal detachments are tethered to the optic nerve and ora serrata.

While posterior segment abnormalities are challenging to diagnose in an emergency room setting with history, fundoscopy, and visual field testing alone, there are clear and distinguishable features on ocular ultrasound that differentiate retinal detachment to a non-pathological eye.

Early diagnosis of Retinal Detachment (RD) can improve the rate of successful reattachment and quality of vision, especially before macular involvement. Point-of-care (POC) ocular ultrasound has been shown to be a reliable diagnostic tool for rapidly evaluating patients with suspected RD.
