RESUMO
This study determined the rate of anterior chamber aerobic bacterial contamination in 103 eyes that had uncomplicated posterior chamber phacoemulsification. Anterior chamber fluid was aspirated on completion of surgery. Cultures of sterile balanced salt solution served as a control. Of 103 anterior chamber cultures, 4 (3.9%) showed contamination; however, 3 of 103 control cultures (2.9%) also grew micro-organisms. These findings suggest a very low rate of aerobic bacterial contamination after uncomplicated phacoemulsification and underscore the importance of control cultures when determining contamination rates.

A 30-year-old obese patient with a rapidly progressing chiasmal syndrome presented with acute bitemporal hemianopia, severe bilateral amblyopia, mental confusion, and lethargy. X-ray films of the skull showed a normal sella turcica and computed tomography scan as well as angiography revealed a vascular mass within the chiasmatic cistern. At operation, via left subfrontal approach, an intrachiasmal hematoma was evacuated and biopsies of the hematoma cavity revealed a cavernous hemangioma. Visual symptoms improved markedly postoperatively. This rare association of chiasmal apoplexy and intrachiasmal cavernoma is discussed.
