Ellipsoid Zone Integrity and Visual Acuity Changes during Diabetic Macular Edema Therapy: A Longitudinal Study

Table 3

Correlation analysis of changes in visual acuity and OCT parameters between baseline to third year and baseline to fifth year. Spearman’s correlation coefficient between change of visual acuity and OCT parameter at each time point is shown. ; ; .

Pooled EZR-RPE distance	0.21	0.33
Central EZR	-0.31	-0.44
Central EZ-RPE distance	0.26	0.21
CRT	0.40	0.34
