Thirty-two eyes with idiopathic macular holes and one eye with a traumatic macular hole were assessed by pattern-reversal electroretinography, ganzfeld electroretinography and pattern-reversal visual evoked potentials. Results were inspected for qualitative abnormalities and then measured in comparison with fellow eyes and 41 control eyes of similar age. Qualitative abnormalities occurred in some eyes with macular holes, most commonly a reduction in pattern-reversal electroretinogram or pattern-reversal visual evoked potential amplitude; 15' check amplitudes were significantly lower in eyes with macular holes than in control eyes, but no significant difference in latency was found. Control pattern-reversal electroretinogram and pattern-reversal visual evoked potential amplitudes were noted to decline with age, and paired t-tests on an age-matched subgroup of eyes with macular holes and control eyes showed appreciable differences only in the pattern-reversal electroretinogram q-r (N95) amplitude.
