A swine model of ocular trauma was used to determine the extent of penetration of systematically administered gentamicin and ceftazidime to the vitreous cavity of traumatized and normal eyes. ⋯ Ceftazidime achieves an intravitreal concentration 33 times the minimum inhibitory concentration of Haemophilus species and twice that of Pseudomonas species in traumatized eyes after systemic administration, a finding that lends support to its use as a prophylactic agent in the management of penetrating ocular trauma. Gentamicin does not appear to enter the traumatized eye at appreciable levels after systemic administration, and, therefore, it is not recommended for use as a prophylactic agent in the management of penetrating ocular trauma.

Case Reports
Endogenous endophthalmitis simulating retinoblastoma. The 1993 David and Mary Seslen Endowment Lecture.
Among conditions that can simulate retinoblastoma, endogenous endophthalmitis is quite rare. ⋯ Differentiation between infectious conditions and retinoblastoma can sometimes be difficult, but clues as to the diagnosis can be obtained from careful clinical examination.
