A 40-year-old patient came to our outpatient department with complaints of defective near vision. The patient had no complaints of floaters, redness, or pain. The patient also gave no history of trauma. On examination, his best-corrected visual acuity was 6/6 in both eyes. Posterior segment examination of the right eye revealed a medium-sized cystic mass with brownish pigments over its surface floating in the vitreous cavity in the inferotemporal quadrant [Figure 1]a.

B-scan [Figure 1]c revealed the inferotemporal location of the cyst measuring around 4.24 × 3.88 mm without hyperdense echo within the cyst thereby ruling out a scolex. UBM [Figure 1]b of the right eye was normal and no ciliary body cysts were found.
The first documented case report of a vitreous cyst was reported by Tansley in 1899. The most important clinical dilemma is to differentiate them from acquired causes, most notably being melanoma and cysticercosis. Acquired cysts are usually creamy-white with accompanying inflammation. Few investigations such as B-scan can identify if the cyst is of a parasitic nature (presence of hyperchogenecity within the cyst suggestive of a scolex);, UBM to see whether any remnants or mass in the uveal tissue can also be done as in our case.
As the cyst was an incidental finding and the investigations were found to be normal, the patient was advised glasses for near-vision correction.
