Name another fourth-generation fluoroquinolone commonly used in ophthalmology.

• A. Besifloxacin
• B. Gatifloxacin
• C. Moxifloxacin
• D. Ciprofloxacin

Answer: (C)

Fourth-generation fluoroquinolones used in the eye are valued for broad coverage, especially against Gram-positive bacteria, and for penetrating ocular tissues effectively. Moxifloxacin fits this profile well: when applied topically, it achieves therapeutic levels in the cornea and aqueous humor and is active against common ocular pathogens, including Staphylococcus species and other bacteria that cause conjunctivitis and keratitis. Its broad spectrum and good ocular penetration make it a reliable, commonly used choice in ophthalmic infections, which is why it’s the preferred pick here.
