The pseudocyst (yellow arrow) can be a signal that the retinal detachment is chronic. The ultrasound helps to clearly define the fluid filled cavity. It is thought that these are formed by schisis cavities in the outer plexiform layer. If closure of the primary break is not possible, or if the pseudocyst extends to the ora serrata, internal drainage may be recommended during retinal detachment repair.
