Table 3. EQ-5D (NZ VAS weighting) utility scores by better or worse eye category and per vision state (by VA category).

				VA categories worse eye
Better eye VA categories			Better eye only	6/12 or better	<6/12–6/18	<6/18
				No VI	Mild VI	Moderate – Severe VI
	6/12 or better	No VI	.71±.23 n = 558	.70±.22 n = 247	.71±.24 n = 170	.73±.23 n = 141
	<6/12–6/18	Mild VI	.69±.23 n = 154		.68±.23 n = 47	.70±.24 n = 107
	<6/18	Moderate –Severe VI	.67±.23 n = 137			.67±.23 n = 137
Worse eye only				.70±.22 n = 247	.70±.24 n = 217	.70±.23 n = 385

VA = visual acuity, EQ-5D = Euro Quality of Life Questionnaire, VAS = visual analogue scale, NZ = New Zealand value set. Bolded data correspond to the 6 vision states relating to combined categories of VI in the better and worse seeing eyes.
