 Linezolid has been studied as an alternative to vancomycin in the treatment of febrile neutropenia in cancer patients when Gram @-@ positive infection is suspected . It is also one of few antibiotics that diffuse into the vitreous humor , and may therefore be effective in treating endophthalmitis ( inflammation of the inner linings and cavities of the eye ) caused by susceptible bacteria . Again , there is little evidence for its use in this setting , as infectious endophthalmitis is treated widely and effectively with vancomycin injected directly into the eye .
