This study was designed to determine the effects of trauma and infection on vitreous ciprofloxacin levels after intravitreal injection of ciprofloxacin in rabbits. ⋯ Infection appears to decrease the clearance of ciprofloxacin. Therapeutic drug levels in traumatized-infected eyes were maintained up to 48 hours. Assuming that the animal model used may have a predictive value for the drug elimination in traumatized-infected human eyes, we suggest that local administration of ciprofloxacin every 2 days may be relevant from the therapeutic perspective.

Comparative Study
Primary intraocular lens implantation during pars plana vitrectomy and intraretinal foreign body removal.
To evaluate visual and surgical outcomes as well as complication rates after cataract extraction and primary intraocular lens (IOL) implantation during pars plana vitrectomy for removal of foreign bodies embedded or impacting in the retina. ⋯ Primary IOL implantation after combined cataract and vitreoretinal surgery is a safe and attractive option, reducing the need for two separate operations in selected patients with penetrating ocular injury and retained intraocular foreign bodies. The main advantage is more rapid visual rehabilitation with a single operation, reducing costs and patient discomfort.
