'Poké Ball' (a device used to capture Pokémons in a game) symbol comprises red and white semicircles with a central button [Figure 1]a., Identical appearance was seen in right eye of a 29-year-old man, wherein hyperoleon in anterior chamber (AC) displaced large silicone oil bubble centrally [Figure 1]b and [Figure 1]c. This oil bubble had migrated in AC before six months, following vitrectomy for retinal detachment associated with irido-lenticulo-retinochoroidal coloboma. Silicone oil bubble in AC resists emulsification compared to same in posterior segment probably due to difference in inertia and shear stress. This may have contributed to 'Poké Ball' appearance.
