Selection of an orbital imaging technique requires a thorough understanding of pertinent anatomy applied to relevant clinical history and detailed ophthalmic examination. The clinical finding should direct the clinician to the imaging study that provides maximum information and narrows diagnostic considerations for the individual patient. Clinical examples are provided to illustrate the rationale in ordering magnetic resonance images, computed tomography, ocular ultrasound, and color Doppler arteriography of orbital processes.

With the emergence of Candida as a major nosocomial pathogen, the authors investigated the prevalence of ocular lesions in patients with candidemia and evaluated risk factors for eye involvement.
Methods: This study is a prospective, multicentered, observational design.
Purpose And Patients And Methods: We performed a prospective clinical study of 200 consecutive patients with Pseudomonas aeruginosa bacteremias to analyze in vitro susceptibility and synergistic testing of antibiotics the patients received and clinical parameters to assess their relationship to survival.
Results: No significant correlation between in vitro susceptibility testing (minimal inhibitory concentrations/minimal bactericidal concentrations) and outcome could be demonstrated. Similarly, improved outcome could not be demonstrated for patients receiving antibiotic combinations that were synergistic in vitro (either time-kill or checker-board) versus those combinations that were not.
