Table 3.

Visual acuity outcomes at each time point.

Visual acuity	Baseline (n = 1,032)	6 months (n = 882)	5 years (n = 848)	10 years (n = 910)
BCVA 6/12 (0.3) or better	653/1,032 (63.3)	555/882 (62.9)	505/848 (59.6)	524/910 (57.6)
BCVA worse than 6/12 but better than 6/60 (1.0) (visual impairment)	181/1,032 (17.5)	169/882 (19.2)	188/848 (22.2)	190/910 (20.9)
BCVA 6/60 or worse (legal blindness)	198/1,032 (19.2)	158/882 (17.9)	155/848 (18.3)	196/910 (21.5)

BCVA best corrected visual acuity.

‘n’ at each time point represents the number of eyes for which data was available and therefore is not a longitudinal change of VA in the same observations.
