Fig 2. The proportion of eyes with (a) significant and (b) complete resolution of hard exudates.

(a) The proportion of eyes with significant absorption of the hard exudates was 29.41%, 94.12%, 100%, and 100% in the vitrectomy group and 12.5%, 47.37%, 88.89% and 88.89% in the control group at post-treatment 3 months, 6 months, 12 months, and final visit. (Fisher exact test, P = 0.0034 at post-treatment 6 months). (b) Complete resolution of hard exudates at 3, 6, 12 months after treatment and final visit was found in 0%, 23.53%, 52.94%, and 64.71% of eyes in the vitrectomy group and 0%, 5.26%, 22.22%, and 38.88% in the control group.
