Association between change in retinal thickness measured by optical coherence tomography (OCT) at the central subfield and change in visual acuity for eyes with uveitic macular edema (defined as retinal thickness ≥ 260 μm). Comparisons are made for scores documenting the overall trends and improvement.

a
The counts and column percentages are included for each combination.
b
P-values are based upon ordinal regression using generalized estimating equations (GEE) to account for within-person, between-eye correlation.
c
P-values are based upon logistic regression using generalized estimating equations (GEE) to account for within-person, between-eye correlation.
