Corneal Backscatters as an Objective Index for Assessing Fuchs’ Endothelial Corneal Dystrophy: A Pilot Study

Table 1

Quantitative parameters in FECD and normal subjects.

	FECD			Normal control
	CCT (μm)	Mean AD (%)	DM/AD	CCT (μm)	Mean AD (%)	DM/AD
Numbers	23	23	23	23	23	23
Median	576	18.10	1.13	551	16.10	0.91
Minimum	511	13.65	0.74	505	13.13	0.79
Maximum	1189	56.48	2.32	667	20.07	1.10

FECD: Fuchs’ endothelial corneal dystrophy; CCT: central corneal thickness; Mean AD: average area density; DM/AD: average ratio of Descemet’s membrane density versus area density.
