Postoperative endophthalmitis often progresses to significant visual impairment. This paper describes an outbreak of Ochrobactrum anthropi endophthalmitis following cataract surgery, and propose a new sterilization protocol to minimize the risk of further cases. Medical records of patients with O. anthropi endophthalmitis or with suggestive clinical findings during the outbreak were reviewed. Seven cases of O. anthropi pseudophakic endophthalmitis were confirmed between 24 July and 10 November 2010. The most probable cause of the outbreak of Ochrobactrum anthropi endophthalmitis was contamination of the tubing of the phaco-emulsification machine. Following introduction of a new sterilization protocol, no further cases occurred in over 1000 subsequent procedures.
SOV was significantly reduced in orbits with congestive GO or with myogenic fibrotic GO, but not in orbits with fibrotic lipogenic orbitopathy. SOV congestion may be a contributing pathogenic factor in both congestive and fibrotic myogenic Graves' orbitopathy.
Mesenchymal chondrosarcoma is a rare malignant tumor of the orbit capable of mimicking several other lesions. Early diagnosis requires a high level of suspicion, particularly with regard to internally calcified lesions. The treatment of choice is complete surgical resection, or, when the tumor is not resectable or residual mass is present after surgery, chemotherapy and radiotherapy. Prognosis for patients with orbital mesenchymal chondrosarcoma is tentative at best, in part because of the rarity of the lesion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
