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.
Presentation of one case of extraocular muscle enlargement caused by cysticercosis, its clinical, diagnostic and treatment aspects, and review of the literature on this theme. A female 38-year-old patient with extraocular muscle enlargement and a small cystic lesion at the superior rectus muscle insertion was treated with oral prednisone for almost one year, with a non-specific inflammation of right orbit diagnosis. There were important ocular motility restriction and pain. Computerized tomography disclosed a superior rectus muscle thickening with a small cystic and apparently empty lesion at the muscle's insertion. Excisional biopsy and histopathological study confirmed the clinical suspicion of cysticercosis. There was partial resolution of the restricted motility. Extraocular muscle cysticercosis is the most common site of this disease when involving the orbit. Oral albendazole and prednisone are efficient, but a long history of disease can lead to important residual ocular motility restriction.

The orbital mass lesions were treated mostly by an expert ophthalmologist. When other specialties were included, there was a modest increase in secondary tumor incidence when the final result was compared with previous studies on this subject. Our findings indicate that the creation of a trustworthy register of all orbital space-occupying lesions in Brazilian specialized services is necessary. The multidisciplinary character of the orbital mass lesions is corroborated by this review.
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.
