Comparison of new psychophysics and perimetry with electrophysiological techniques in the diagnosis of glaucoma.
Many accounts show that the pattern electroretinogram is a sensitive index of glaucomatous visual damage, and can demonstrate losses before field defects are apparent.  If the pattern electroretinogram is not specific, and although it is likely to have a role in patient management, it is not a screening technique.  Many psychophysical tests, particularly of titan color vision, appear to be promising in this regard.
