Table 1 Demographics

	CME	No CME	p-value
Total number of eyes	22	221
Mean age (years)	65.7 ± 4.7 (range: 55–77)	65.3 ± 6.2 (range: 50–79	p=0.76
Percentage of females	77.3%	67%	p=0.324
Mean logMAR visual acuity (Snellen equivalent)	0.58±0.42 (20/80)	0.54±0.41 (20/70)	p=0.65
Mean central macular thickness prior to macular surgery (microns)	475±108 (range: 207–609)	443±93 (range: 223–791)	p=0.19
Mean central macular thickness prior to cataract surgery (microns)	348±95 (range: 137–480)	299±85 (140–538)	p=0.03
