1. Knowledge of slit lamp illumination techniques along with solid concepts of 
the disease processes can allow an understanding of the visible morphologic 
structures seen in the disease process during examination with the 
biomicroscope. 2. Inflammation can be defined as the interaction between a 
stimulus and a host, frequently resulting in some degree of structural change 
within the host. 3. The cellular responses include a predictably sequential 
order of events. The four cardinal signs of inflammation are redness, swelling, 
heat, and pain, phenomena explained at the cellular level.
