Purpose: To compare findings by frequency doubling perimetry (FDP) and by Humphrey visual field analyzer (HFA) in patients with compressive lesions in the chiasmal area. FDP findings are supposed to reflect the magnocellular projection in the retinal ganglion cells.

Cases and Methods: We evaluated 14 patients with hemianopia secondary to compressive chiasmal lesions and 20 normal persons. All the cases were examined by HFA central 30-2 and by FDP c-20 threshold tests. We compared the measuring time, MD, PSD, and hemianopic ratio between the two methods.

Results: The measuring time averaged 4.6 min for FDP and 14.4 min for HFA. There were significant correlations between the two methods regarding MD, PSD, and hemianopic ratio. Changes in hemianopic ratio before and after surgery were the same in 16 patients (80%) by FHA and FDP.

Conclusion: FDP was useful in detecting chiasmal compressive lesion with hemianopia.
