Visualization of the Posterior Precortical Vitreous Pocket In Vivo With Triamcinolone

Arch Ophthalmol. 2006;124(11):1663. doi:10.1001/archopht.124.11.1663

The premacular bursa, a liquefied area of vitreous anterior to the macula, was first described by Worst1after he observed a complex system of vitreous cisterns and communicating tracts by staining the vitreous with india ink post mortem. Kishi and Shimizu2described a similar structure in fluorescein-stained autopsy eyes, which they termed the posterior precortical vitreous pocket (PPVP). However, some anatomists believed the vitreous to be amorphous in the living eye and rejected the observations of Worst as ex vivo fixation artifact.1The PPVP appears to be visualized with ultrasonography,3but direct in vivo observation of this structure is lacking in the literature.
