Table 3 Visual acuity outcomes at each time point.

From: Prevalence and incidence of visual impairment in patients with proliferative diabetic retinopathy in India

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)

  1. BCVA best corrected visual acuity.
  2. ‘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.
