Answer: C - Illuminates entire area (nonspecific)

Diffuse slit-lamp illumination illuminates the entire area (nonspecific). To achieve this technique, the beam is opened all the way and directed onto the eye at a 45 degree angle while the microscope is directed straight ahead. This is best used to view the eyelashes, eyelids, sclera, conjunctiva, patterns of redness, iris, and pupil.
