High-pass resolution perimetry in neuro-ophthalmology. Clinical impressions.

Abstract

High-pass resolution perimetry is a new technique for visual field testing that determines extrafoveal resolution thresholds. The authors used this method in a neuro-ophthalmology clinic and compared it with other visual field tests. The main advantages of the technique were the short test time and the strong preference by patients for this technique over conventional automated perimetry. The sensitivity and specificity of the test seemed to be as good as or better than conventional perimetry. A minor disadvantage was its slightly less precise spatial definition of field defects. In this report, the authors present their experiences with this new perimetric technique.
