Overview
Bacterial endophthalmitis means bacterial infection inside the eye, involving the vitreous and/or aqueous humors. Most cases of endophthalmitis are exogenous, and organisms are introduced into the eye via trauma, surgery, or an infected cornea. Endogenous endophthalmitis occurs when the eye is seeded via the bloodstream. Patients usually have symptoms from their underlying systemic infection, but sometimes present only with eye symptom
Historical Perspective
Classification
Bacterial endophthalmitis may be classified based on who Infectious agents generally gain access to the posterior segment of the eye into 2 subtypes: exogenous and endogenies.
Based on who Infectious agents generally gain access to the posterior segment of the eye, bacterial endophthalmitis may be classified into:
- Exogenous bacterial endophthalmitis
- Postoperative bacterial endophthalmitis (consequence of intraocular surgery)
- Posttraumatic bacterial endophthalmitis (following a penetrating injury of the globe)
- Endogenous bacterial endophthalmitis (hematogenous spread of bacteria to the eye from a distant anatomical site)
