An approach to diagnosis of orbital disease

In spite of advances in investigative technology as applied to orbital disease, clinical judgement remains the most important tool in diagnosis. A model for a clinical approach to the diagnosis or orbital disease is presented in this paper. Defining the location of and the dynamic alteration induced by the disease sets the stage for investigation. The location of the disease is determined by changes induced in the position of orbital structures. Characterizing the dynamic alteration involves assessing evidence of temporal change and signs of the disease process--inflammation, a mass effect or infiltration. Synthesis of the information gained will improve clinical judgement.
