Retinal Detachment 1
This patient presented with a curtain like loss of part of their nasal visual field from the right eye.
The detached retina is visible as a free floating echogenic membrane separated from the globe posteriorly. It moves with eye movement and is usually evident with normal gain settings.
The retina is never detached at the site of the optic nerve.
There is usually an associated vitreous detachment. Increasing the gain settings will reveal the vitreous detachment. A thinner separated membrane, often with small web-like echogenic particles is visible in the globe, and swirls with eye movement. Vitreous detachment, unlike retinal detachment, can occur at the site of the optic nerve. In this example an associated vitreous detachment is evident as a very thin membrane just above the retinal detachment seen on the video clip.
