Intra‐twin correlations for rate of change in retinal layer thicknesses over time

	Correlation coefficient	p‐Value
Macula:
Δ total inner ring	0.242	0.052
Δ total outer ring	0.316	0.011
Δ RNFL inner ring	0.092	0.466
Δ RNFL outer ring	0.189	0.136
Δ GCL inner ring	0.182	0.148
Δ GCL outer ring	0.160	0.205
Δ IPL inner ring	0.262	0.035
Δ IPL outer ring	0.165	0.191
Δ pRNFL	0.280	0.025

GCL = Ganglion Cell Layer, IPL = Inner Plexiform Layer, RNFL = Retinal Nerve Fibre Layer.

Values in bold are significant (p < 0.05).
