Floaters

Floaters are small spots, threads, or cobweb-like shapes that drift across your field of vision. Most are caused by harmless changes in the vitreous gel of the eye, but a sudden increase in floaters can signal a serious problem.

Quick Facts

  • ICD-10: H43.3

Causes

  • Age-related vitreous shrinkage and posterior vitreous detachment
  • Nearsightedness (myopia)
  • Recent eye surgery or trauma
  • Inflammation inside the eye
  • Bleeding into the vitreous (diabetic eye disease)
