Examination of the EOG is surely worthwhile in cases of generalized pigment alteration and in juvenile foveal dystrophies. Its value in the control of chloroquine treatment is still doubted, but the method will become better if an EOG is made before treatment is started. EOGs made during the treatment can then be compared with those made earlier. As a result, the large interindividual variation is replaced by the much smaller intraindividual variation. In a group of normals and patients, the intraindividual standard deviation appeared to be about 10% of the original value of the EOG. Using this criterion, we think the EOG to be a valuable tool in preventing chloroquine retinopathy, although it is not yet certain if static perimetry with red light is still a better method.

In the clinical standard EOG procedure the light rise potential is influenced by the preceding dark troughs oscillation. This is apparent in the different configuration of the light rise potential when following a dark trough instead of a steady state. Uninfluenced responses can be obtained only under steady-state conditions. Recording of the light peak potential in this manner may be used on a trial basis for clinical routine examination. Experimental and more detailed clinical studies require separate recording of light peak and dark trough potential, each preceded by a steady state. The evaluation of these responses, expressing them in percent of the steady state, should reveal more information than can be expected from the standard light peak to dark trough ratio.
