Visual acuity

Effect measure

Mean change in logMAR visual acuity from baseline, measured by ETDRS chart

Mean BCVA from Snellen chart and then converted to a numerical equivalent number; linear regression model

Mean difference in logMAR BCVA between groups from multiple linear regression model, using a protocol adapted from AREDS using a tumbling "E" chart

Time point(s) measured

10 weeks

2 months

3 weeks, 3 months, 12 months

3 weeks and 3 months

Estimate

Steroid group: ‐0.31 (SD or 95% CI not reported)

Control group: ‐0.18 (SD or 95% CI not reported)

1) Mean BCVA:

Steroid group: mean pretreatment vision: 6; mean post‐treatment vision: 9.7

Non‐steroid group: mean pretreatment vision: 6.4; mean post‐treatment vision: 9.2

2) Linear regression model: linear regression showed no difference between groups

3 weeks: steroid group had 0.024 better logMAR BCVA (95% CI ‐0.092 to 0.044)

3 months: steroid group had 0.009 better logMAR BCVA (95% CI ‐0.085 to 0.068)

12 months: steroid group had 0.04 better logMAR BCVA (95% CI ‐0.12 to 0.05)

1) Mean (SD) logMAR BCVA:

3 weeks: steroid group: 0.66 (0.68); placebo group: 0.75 (0.75)

3 months: steroid group: 0.71 (0.72); placebo group: 0.59 (0.75)

2) Multiple linear regression model:

3 weeks: steroid group had 0.19 lower (better) logMAR BCVA (95% CI ‐0.52 to 0.15)

3 months: steroid group had 0.09 lower (better) logMAR BCVA (95% CI ‐0.41 to 0.24)

Interpretation

No statistically significant difference between groups was found

No statistically significant difference between groups was found

Healing rate/ulcer size

/time to re‐epithelialization

Effect measure

Control group: ‐1.919 mm2

(SD or 95% CI not reported)

Clinician estimate (slit lamp):

Steroid group: ‐4.206 mm2

Control group: ‐0.789 mm2

(SD or 95% CI not reported)

Steroid group: 0.36 mm2 per day

Control group: 0.30 mm2 per day

Ulcer size:

3 weeks: steroid group had 0.05 mm smaller diameter of scar area (95% CI ‐0.09 to 0.15)

3 months: steroid group had 0.06 mm smaller diameter of scar area (95% CI ‐0.07 to 0.17)

12 months: steroid group had 0.03 mm smaller diameter of scar area (95% CI ‐0.12 to 0.18)

Time to re‐epithelialization:

Steroid group: 7.5 days (95% CI 5.5 to 8.5 days)

Placebo group: 7 days (95% CI 5.5 to 8.5 days)

Ulcer size:

3 weeks: steroid group had 0.57 mm smaller diameter of scar area (95% CI 1.5 to 0.37)

3 months: steroid group had 0.33 mm smaller diameter of scar area (95% CI 1.4 to 0.75)

Time to re‐epithelialization:

steroid group: 8.6 days (SD 4.7)

placebo group: 6.3 days (SD 3.1)

Interpretation

No statistically significant difference between groups from photographic measurement;

statistically significant difference between groups from clinician estimate

No statistically significant difference between groups was found

No statistically significant difference between groups was found

No statistically significant difference between groups was found
