Relationship between BCVA and the MV and MH scores

Visual acuity (logMAR)	MV score	MH score
Pre	r=0.03	r=0.11
Pre	P=0.92	P=0.73
Post 1 month	r=0.38	r=0.36
Post 1 month	P=0.22	P=0.25
Post 3 months	r=0.53	r=0.45
Post 3 months	P=0.08	P=0.14
Post 6 months	r=0.20	r=0.20
Post 6 months	P=0.54	P=0.53

Notes: There were no significant correlations between BCVA and MV and MH scores before surgery (r=0.05, P>0.05 for MV; r=0.006, P>0.05 for MH; Spearman rank correlation coefficient) and at 6 months after surgery (r=0.21, P>0.1 for MV; r=0.35, P>0.1 for MH). However, there were significant correlations between BCVA and MV and MH scores at 1 month after surgery (r=0.5, P<0.05 for MV; r=0.5, P<0.05 for MH) and at 3 months after surgery (r=0.6, P<0.01 for MV; r=0.49, P<0.05 for MH).

Abbreviations: BCVA, best-corrected visual acuity; MV, vertical metamorphopsia; MH, horizontal metamorphopsia; logMAR, logarithm of the minimum angle of resolution.
