When dealing with eye infection antibiotics, medications used to treat bacterial infections of the ocular surface and internal eye structures. Also known as ocular antibiotics, they are prescribed to clear conjunctivitis, inflammation of the conjunctiva usually caused by bacteria or viruses, keratitis, infection of the cornea that can threaten vision if not treated promptly, and other bacterial eye infections. Eye infection antibiotics come in two main delivery forms: topical antibiotic drops, liquid solutions applied directly to the eye surface or ointments, and systemic antibiotics, oral or injectable drugs that reach the eye through the bloodstream. The choice depends on the location and severity of the infection, the organism involved, and patient factors like age or allergies. For mild bacterial conjunctivitis, a short course of topical drops such as azithromycin or fluorometholone‑combined formulations often clears the infection within a few days. In deeper or resistant keratitis, clinicians may add systemic fluoroquinolones or even fortified topical preparations to achieve higher drug concentrations.
The selection process follows a few practical steps. First, identify the type of infection: surface (conjunctivitis) versus deeper (keratitis). Next, consider the likely pathogen—Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, or Haemophilus influenzae—because each responds best to specific drug classes. Third, assess drug properties: spectrum of activity, ability to penetrate the cornea, dosing frequency, and side‑effect profile. For example, macrolides like azithromycin offer convenient once‑daily dosing and are gentle on the ocular surface, making them popular for children. Fluoroquinolones such as ciprofloxacin provide broad coverage, especially against Pseudomonas, but they may cause irritation in sensitive eyes. When a bacterial culture is available, targeted therapy reduces the risk of resistance, a growing concern highlighted by recent studies on ocular antibiotic stewardship. In cases where the infection spreads beyond the eye, systemic antibiotics become essential; they reach intra‑ocular tissues that topical drops cannot, ensuring the infection is fully eradicated.
