Traumatic Posterior Vitreous Detachment with Chorioretinal Scar and Weiss Ring
Traumatic Posterior Vitreous Detachment with Chorioretinal Scar and Weiss Ring
In the fundus photo a (traumatic) posterior vitreous detachment (PVD) found one year later in a young man with a chorioretinal scar dark adjacent to the PVD. There is a Weiss ring present in this patient shaped in an oval configuration, which occurs when the vitreous is detached from the optic nerve.
Blunt trauma to eye can cause a post vitreous detachment and the scar as presented in this case. Blunt trauma can also cause a retinal detachment and retina tears.
The most critical concern with blunt trauma to the eye is the possibility for retinal detachment.
