Editing Floater (section)

=== Other common causes ===
Patients with [[retinal tear]]s may experience floaters if [[red blood cell]]s are released from leaky blood vessels, and those with [[uveitis]] or vitritis, as in [[toxoplasmosis]], may experience multiple floaters and decreased vision due to the accumulation of [[white blood cell]]s in the vitreous humour.<ref>{{cite web|url=http://www.optometry.co.uk/uploads/articles/640c1a5b606a7d89320511ca29ccc288_kabat20010323.pdf|title=A clinician's guide to flashes and floaters|author=Alan G.

Other causes for floaters include [[cystoid macular edema]] and [[asteroid hyalosis]]. The latter is an anomaly of the vitreous humour, whereby [[calcium]] clumps attach themselves to the collagen network. The bodies that are formed in this way move slightly with eye movement, but then return to their fixed position.{{citation needed|date=August 2017}}
