Intergroup comparison of patients with an intact IS/OS layer and patients with an irregular IS/OS layer

	Intact IS/OS	Irregular IS/OS	P*
Number of eyes	29	22
BCVA pre-surgery ± SD	0.30 ± 0.04	0.19 ± 0.02	0.042
Mean CFT pre-surgery ± SD	404 ± 72.15	422 ± 76.30	0.555
Cystic macular edema, n (%)	0 (0)	14 (63.63)	0.001
Macular pseudohole, n (%)	1 (3.44)	2 (9.09)	0.571
Mean CFT post-surgery ± SD	312.67 ± 59.89	344.08 ± 41.95	0.126
BCVA post-surgery	0.69 ± 0.07	0.32 ± 0.07	0.002
Change in BCVA ± SD	0.44 ± 0.24	0.08 ± 0.18	0.001

Notes: Change in BCVA = BCVA after surgery – BCVA before surgery.

^*Mann–Whitney test, Wilcoxon test.

Abbreviations: BCVA, best-corrected visual acuity; CFT, central foveal thickness; IS/OS, inner segment/outer segment; SD, standard deviation.
