Bacterial corneal ulcer infection

A bacterial corneal ulcer infection, also known as bacterial keratitis, is an acute, vision-threatening ocular condition characterized by an epithelial defect with underlying stromal inflammation, necrosis, and suppurative infiltration caused by pathogenic bacteria Pathophysiologically, disruption of the protective corneal epithelium allows bacterial invasion—frequently involving species such as *Pseudomonas aeruginosa*, *Staphylococcus aureus*, or *Streptococcus pneumoniae*—triggering rapid hos...

It primarily affects the anterior segment of the eye, with heightened prevalence among contact lens wearers, individuals with ocular trauma, and patients with underlying corneal disease or systemic immunosuppression

Pathophysiologically, disruption of the protective corneal epithelium allows bacterial invasion—frequently involving species such as *Pseudomonas aeruginosa*, *Staphylococcus aureus*, or *Streptococcus pneumoniae*—triggering rapid host leukocyte recruitment and enzymatic stromal melting

Defining clinical features include severe ocular pain, conjunctival injection, photophobia, decreased visual acuity, and visible stromal infiltrates, which carry substantial risk for permanent corneal scarring, perforation, and endophthalmitis if not promptly treated
