On examination of the right eye fundus, we noted a grayish brown translucent oval-shaped structure in the vitreous, which was freely floating mobile and not attached to the retina [Figures 1a, b].

On further examination of the cyst, it was found to be nonlobulated, pigmented, and mobile with a smooth surface, with an attached small stalk-like tapered vitreous strand [Figures 2a, b and 3b, d].

On further examination of the cyst, it was found to be nonlobulated, pigmented, and mobile with a smooth surface, with an attached small stalk-like tapered vitreous strand [Figures 2a, b and 3b, d]. On investigating with a B scan ultrasonography, it was found to be a small, oval hypoechogenic mass with hyperreflective borders, which was not attached to any posterior surface [Figure 3c]. On spectral domain-optical coherence tomography, it was found that the posterior vitreous was intact, and the macular scan showed no abnormality [Figure 3a].
