 DLTV subscales and levels of care

DLTV subscale	Subscale 1 (resolution items)	Subscale 2 (complex visual tasks)	Subscale 3 (confidence related items)	Subscale 4 (light and dark adaptation)
Level 1: Cannot care for self (27)	18 (22)	41 (24)	27 (15)	47 (31)
Level 2: Can look after self but not others (26)	27 (25)	60 (22)	37 (19)	64 (28)
Level 3: Can care for self and others (146)	61 (32)	82 (22)	58 (22)	68 (26)
One way ANOVA	p<0.001	p<0.001	p<0.001	p<0.01

DLTV  =  daily living tasks dependent on vision. Marked differences in mean subscale scores are seen between the care levels in subscales 1 and 2.
