*Floaters* are deposits of various size, shape, consistency, refractive
index, and motility within the eye’s vitreous humour, which is
normally transparent.^[1]^[2] At a young age, the vitreous is transparent,
but as one ages, imperfections gradually develop. The common type of
floater, which is present in most people’s eyes, is due to
degenerative changes of the vitreous humour. The perception of floaters is
known as /myodesopsia/,^[3] or less commonly as /myodaeopsia/,
/myiodeopsia/, /myiodesopsia/.^[1] They are also called /Muscae volitantes/
(Latin: "flying flies"), or /mouches volantes/ (from the French). Floaters
are visible because of the shadows they cast on the retina^[4] or
refraction of the light that passes through them, and can appear alone or
together with several others in one’s visual field. They may appear as
spots, threads, or fragments of cobwebs, which float slowly before the
observer’s eyes.^[2] Since these objects exist within the eye itself,
they are not optical illusions but are entoptic phenomena.
