The Effect of Biomicroscope Illumination System on Grading Anterior Chamber Inflammation

Ability to count beads and perhaps the ability to count inflammatory cells in an inflamed eye depend on a number of factors, including the level of illumination and width of the slit-beam. This study demonstrated that the brighter the illumination and the wider the beam, the more beads were observed. This illustrates the importance of standardizing biomicroscopy, particularly where consecutive observations are used to make clinical decisions and in cases of multicenter clinical trials where clinical data are evaluated across different facilities.
