[The Bebié curve (cumulative defect curve) for differentiating local and diffuse visual field defects]

Damage to the visual field can be diffuse as well as local. In the absence of local defects, diffuse damage can easily be recognized with the help of the visual field indices. In the presence of scotomas, diffuse damage in the remaining part of the visual field which is better or "normal" is more difficult to recognize and quantify. Bebié et al. have published a new method of assessing the visual field in relation to normal values. They present the results with a cumulative defect curve, a method which we have called the "Bebié curve". This method allows an easy recognition of diffuse as well as local damage. In our study we evaluate the clinical application of the Bebíe curve in different diseases and for the follow-up of the visual field.
