Bacterial keratitis

Bacterial keratitis is an acute, potentially sight-threatening infection of the corneal tissue caused by pathogenic bacteria, most commonly species such as *Staphylococcus aureus*, *Streptococcus pneumoniae*, or *Pseudomonas aeruginosa* It primarily affects the ocular system, occurring most frequently in individuals with predisposing risk factors such as contact lens wear, corneal trauma, or compromised ocular surface defenses Hallmarks of the condition include rapid onset of severe eye pain, co...

It primarily affects the ocular system, occurring most frequently in individuals with predisposing risk factors such as contact lens wear, corneal trauma, or compromised ocular surface defenses

Pathophysiologically, disruption of the corneal epithelial barrier allows bacterial adherence, invasion, and induction of an intense inflammatory response, leading to corneal ulceration, stromal infiltration, and tissue necrosis

Hallmarks of the condition include rapid onset of severe eye pain, conjunctival injection, photophobia, mucopurulent discharge, decreased visual acuity, and, in advanced presentations, hypopyon or corneal perforation
