FIG 1. A, Axial CT scan without contrast demonstrates attenuated fluid collection within the posterior vitreous cavity (asterisk) and smaller deposits in the ora serrata region (arrowheads) forming a fluid-fluid level with the native vitreous humor. PFO can also be seen within the anterior chamber (white arrow).

B, Axial CT with bone algorithm and bone windows demonstrates a retinal detachment (black arrows) and the two components of the collection, the one anterior to the detached retina and the second within the subretinal space extending to the ora serrata. PFO is also seen within the anterior chamber (white arrows).

C, Coronal CT reformat with bone windows demonstrates the corrugated surface of the PFO collection corresponding to the PFO bubbles seen intraoperatively.
