Penetration of ciprofloxacin into aqueous humor.

Ciprofloxacin is a potentially useful antibiotic in eye infection. A pilot study was performed on 25 patients undergoing routine cataract surgery to assess the penetration of the drug into aqueous humor after oral administration. The mean peak level of 0.56 mg/l achieved in aqueous is above the MIC for most gram negative organisms, including Pseudomonas aeruginosa.
