floatersSemitransparent, shadowy bodies seen in the field of vision, usually remote from the point of observation, and moving rapidly with eye movement. For centuries, floaters have been called ‘muscae volitantes’ because of their resemblance to flitting flies. Most floaters are shadows of developmental remnants in the jelly-like VITREOUS HUMOUR of the eye and are harmless. Sudden onset of very conspicuous dark floaters, especially if accompanied by flashes of light (phosphenes) suggest an incipient RETINAL DETACHMENT.

Translucent specks that float across the visual field, due to small objects floating in the vitreous humor.
