Answer

The most important structure to examine is the anterior chamber, as follows:

  • Examine the anterior chamber using a vertically and horizontally short beam.
  • Normally, the aqueous humor in the anterior chamber is optically clear.
  • In uveitis, an increase in the protein content of the aqueous causes an effect upon examination known as flare, which is similar to that produced by a moving projector beam in a dark smoky room.
  • White or red blood cells may be observed; layering of white blood cells in the anterior chamber is called hypopyon.
