A 54-year-old woman with type 2 diabetes mellitus presented to the ophthalmology clinic for a routine dilated fundus examination. Slit-lamp examination of the left eye revealed multiple sparkling, white, globular, refractile, dotlike opacities in the vitreous cavity. The opacities moved with ocular movement and returned to their original position after movement stopped. The vitreous of the right eye appeared normal. The visual acuity was 20/20 in each eye, and the fundus in each eye was normal.
