Table 2. The inter-later reliability of intraclass correlation coeffients for the two observers on AO-SLO measurements.

		Intraclass correlation coeffients
		The inter-later reliability	95% confidence interval
Normal	Cone density (cones/mm2)	0.955	0.931–0.971
	Ratio of hexagonal Voronoi domain(%)	0.811	0.712–0.876
	Average NND/expected NND	0.951	0.909–0.971
RP	Cone density(cones/mm2)	0.980	0.966–0.988
	Ratio of hexagonal Voronoi domain(%)	0.697	0.520–0.809
	Average NND/expected NND	0.923	0.834–0.959

NND: nearest-neighbor distance, RP: retinitis pigmentosa.
