In the absence of detachment of the retina, nonparasitic cystic structures in the vitreous are extremely rare. They have been reported as varying in appearance from a free-floating semitransparent body to a cyst associated with or attached to a solid structure in the posterior segment of the eyeball. A thorough search of the literature reveals three examples of bilateral cyst of the vitreous.
The first case, reported by Vennin1 in 1910, occurred in a highly myopic 22 year old soldier. The vitreous of each eye contained a floating greenish sphere, moving with movements of the eyeball and suspended from short filaments which appeared to fuse with the framework of the vitreous. The presence of these bodies produced no subjective disturbances or changes in the visual fields. The author believed them to be congenital remains of the hyaloid apparatus.
The second example, recorded by Lacarrere2 in 1929,
