Abstract

The authors conducted a study in 100 non-smoker healthy normal human subjects to find a relationship between eye dominance and macular function as tested by using transient stimulus and electroretinography. Eye preference procedure was carried out using two reference points and pattern electroretinograms (PERGs) were recorded using black and white checks, each check subtending 23'. Trace averages was retriggered every 300 milliseconds (ms) with data collection time of 150 ms. The difference in PERG P-50 amplitudes between right and left eyes was analyzed, using Student's t test. There was no significant difference in PERG P-50 amplitudes between the right and left eve dominant subjects as well as no significant differences between the right and left eyes in right eve dominants and left eye dominant, but in the left-eye doininant group the left eye PERG Pro amplitudes were significantly higher in females than males. Although pattern-reversal visual evoked potentials of healthy subjects provide electrophysiological evidence of lateralization in the nervous system, sensory eye dominance seems to have no correlation with macular function.
