[Intraocular penetration of topical norfloxacin in humans. Preliminary study]. / Pénétration intra-camérulaire de la norfloxacine locale chez l'homme. Etude préliminaire.

The aim of this bicentric study was to assess the intraocular penetration of topical Norfloxacin. Herein, are only reported the results from one center. Topically applied Norfloxacin 0.3% was given to patients who underwent cataract surgery. The first group received 5 drops between 7.55 A.M. to 8 A.M. and after each hour until cataract surgery. The second one received one drop each quarter from 7 A.M. until the surgery. Aqueous and sera samples were dosed using HPLC. In the first group, the aqueous average was 0.066 mg/l and 0.112 mg/l in the second group. Using a T test and Mann Whitney test, we could not find a significant difference between the two groups.
