Correlations between the repeated measurements for horizontal diameter, vertical diameter, and ring area of the hyperautofluorescent rings at visit 1 and 2.

	Horizontal diameter				Vertical diameter				Ring area
	SW-AF		NIR-AF		SW-AF		NIR-AF		SW-AF		NIR-AF
Pearson correlation	Visit 1	Visit 2	Visit 1	Visit 2	Visit 1	Visit 2	Visit 1	Visit 2	Visit 1	Visit 2	Visit 1	Visit 2

SW-AF = short-wave autofluorescence; NIR-AF = near-infrared autofluorescence; r = Pearson correlation coefficient.
