We evaluated the value of relative afferent pupil-lary defect (RAPD) as measured by swinging flash-light test in 35 cases with various optic nerve lesions including glaucoma, pituitary tumor, trauma to the optic nerve and ischemic optic neuropathy. We compared quantified RAPD with other standard indicators of visual function.

There was no significant correlation between RAPD and visual acuity. A close relationship existed between RAPD and critical flicker fusion frequency (CFF). It was generally possible to reciprocate the CFF pattern in the affected eye by placing a neutral density filter before the fellow, intact eye. While RAPD was proportional to the extent of impaired CFF or visual field, the amount of RAPD was most clearly correlated with the depth or volume of the central visual field and the foveal threshold. The latter values could be measured either by Goldmann perimeter or suprathreshold static perimeter.
