Nocardia infection of the eye is uncommon. A case of choroidal abscess due to Nocardia farcinica infection is presented, and the literature is reviewed. ⋯ Nocardiosis is a multisystem disease that has high mortality and ocular morbidity rates. The eyes of immunocompromised patients should be examined frequently as early detection and administration of the proper antibiotics may reduce the risk of this life-threatening infection.

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.

This report evaluates the clinical characteristics of surfing-related ocular trauma to learn the nature of such injuries and propose possible preventive measures. ⋯ Surfing-related ocular trauma presenting to the retinal specialist typically leaves the patient with a permanent visual disability. Important factors contributing to these high-velocity injuries include the sharply pointed nose of the surfboard and the leash keeping the surfer in close proximity to the board following a fall. A simple modification in surfboard design such as blunting the sharp nose of the surfboard, or appropriate protective guards fitted over the surfboard nose, should lessen the severity of such injuries.
