Burden and Depression among Caregivers of Visually Impaired Patients in a Canadian Population

Table 2

The modified Burden Index of Caregivers scores among caregivers of patients with varying degrees of visual impairment.

	Group 1	Group 2	P value
Time-dependent burden			<0.01
Emotional burden			<0.01
Existential burden			<0.01
Physical burden			<0.01
Service-related burden			<0.01
Personal estimate of overall burden			<0.01
Total mean BIC			<0.01

P value calculated using independent two-tailed -tests showed that values for Group 2 were significantly higher for each domain. Group 1: best corrected visual acuity in the better eye > 6/60 yet worse than 6/18. Group 2: best corrected visual acuity in the better eye ≤6/60 (legally blind).
