Data from Jacobson et al^4,5 analysed for interocular percentage difference

	Photopic		Scotopic
	Single flash (%)	30 Hz flicker (%)	Isolated (blue) (%)	Maximal white (%)
Mean (SD)	7 (6)	7 (4)	5 (4)	8 (9)
Range	1–25	1–15	1–15	1–33

*A percentile represents the maximal interocular percentage difference in the percentile of the population.

†The 50th percentile represents the median.
