RESUMO Foram estudados laboratorialmente casos diagnosticados clinicamente como endoftalmite, no período compreendido entre 1985 a 1993, num total de 134 casos. O fator desencadeante mais freqüente foi a intervenção cirúrgica (66,2%), seguido pelo trauma (25,4%). Dos 134 casos, 52 apresentaram cultura positiva (39%). O agente etiológico predominante foi o Staphylococcus aureus. Quanto à sensibilidade aos antibióticos, todos os microrganismos eram sensíveis à vancomicina, cefalotina, gentamicina e tobramicina.

SUMMARY We reviewed 134 cases with clinical diagnosis of endophthalmitis sent to our Microbiology Service. Cataract surgery was the main cause of endophthalmitis (66.2%), followed by trauma (25.4%). The most frequent isolated microrganism was Staphylococcus aureus. All of them were suscetible to cephalotyn, vancomicyn, gentamicyn and tobramicyn.

SUMMARY We described a 47-year-old man with a noninflammatory bilateral corneal ectasia. Superior thinning was present between 11 and 2 hours, with a localized steep area coincident to the thinning. An edge of apparently non-affected cornea was observed adjacent to the limbus. No deposits, stress lines or deep neovascularization was observed. This case does not match classic descriptions such as keratoconus or pellucid marginal degeneration. Differential diagnosis among noninflammatory ectasia are discussed, focusing in the same-pathology theory.
