Introduction

  • Not a true inflammation of the vitrea as vitreous is avascular. Always indicates inflammatory mediator in vitreous from retro choroiditis or intermediate uveitis/pan planitis.
  • Cause: extension from suppurative chorioretinitis, endophthalmitis, penetrating injury.
  • Treatment: topical and systemic anti-inflammatory drugs, antibiotics.

Pathogenesis

Pathophysiology

  • As the adult vitreous has no intrinsic vasculature or nerve supply, it can only react in limited ways to injury. The vitreous is 99% water and 1% hyaluronine decidual collagen.
Vitritis
  • Anterior uveitis.
  • Chorioretinitis.
  • Retinal detachment.
  • Trauma, eg gun pellets.
  • Intraocular neoplasia.
  • Persistence of fetal vasculature.
  • Collie Eye Anomaly Collie eye anomaly.
  • Systemic hypertension.
  • Infection, blastomycosis, brucellosis, histoplasmosis.
  • Floaters of hemorrhagic or other exudate origin in the vitreous (especially if diffuse or bilateral), result from uveitis, chorioretinitis, of optic perforating, vitrogenic or blunt trauma, to vitral detachment, or to intraocular neoplasia.
