Background
- Infectious of the vitreous or aqueous humour
Category | Organisms | Clinical Findings |
---|---|---|
Trauma | Bacillus, coagulase-negative staphylococci, Pseudomonas, molds | open globe, may be fulminant with Bacillus |
Surgical | ||
Post-cataract | coagulase-negative staphylococci, Staphylococcus aureus, streptococci, Gram-negative bacteria | aching pain with vision loss |
Pseudophakic (chronic post-cataract) | Cutibacterium acnes | pain, vision loss, visible plaque in lens |
Intravitral injection | coagulase-negative staphylococci, streptococci | pain and vision loss, hypopyon |
Bleb-related | streptococci, Moraxella, Haemophilus influenzae | pain and vision loss, may have redness, hypopyon |
Endogenous | ||
Bacteremia | streptococci, coagulase-negative staphylococci, Staphylococcus aureus, Bacillus | pain and vision loss, maybe fever |
Fungemia | Candida, Aspergillus species | vision loss, fluffy vitreal lesions |
Risk Factors
- Surgery or trauma
- Diabetes mellitus
- Injection drug use
Clinical Manifestations
- Blurry vision, redness, often pain
- Occasionally swollen lid
- Often has a hypopyon
Differential Diagnosis
- Occult retention of lens cortex or nucleus
- Uveitis
- Non-infectious hypopyon uveitis (Behçet disease or rifabutin)
- Posterior uveitis
- Infectious: syphilis, tuberculosis, toxoplasmosis, or toxocariasis in children)
- Non-infectious: Vogt-Koyanagi-Harada disease, collagen vascular disorders, systemic vasculitides, or idiopathic)
- Inflammatory reaction to intravitreal drug
- Blebitis
- Acute retinal necrosis
- Keratitis
- Intraocular lymphoma
Management
- Systemic and intravitreal antimicrobials directed at the pathogen
- Ensure ocular penetration (similar to CNS penetration)
- May require surgery or vitrectomy
