Table 4 Comparison of refractive change before and after ptosis repair surgery in the data from refractions before and 3 months after ptosis repair surgery

From: Refractive error characteristics in patients with congenital blepharoptosis before and after ptosis repair surgery

(Number, 26 eyes) Preoperation Postoperation P value
SER (Mean ± SD) 0.65 ± 1.79 0.25 ± 1.94 0.22
Astigmatism (range) −1.67 ± 1.32 (−5.25 ~ 0) −1.86 ± 1.16 (−4.25 ~ −0.5) 0.30
Astigmatic type number (%)    0.04*
 OA 10 (38.5 %) 19 (73.1 %)  
 WTR 13 (50.0 %) 6 (23.1 %)  
 ATR 3 (11.5 %) 1 (3.8 %)  
 Amblyopia 6 (23.1 %) 9 (34.6 %)a 0.37
  1. (Total numbers of eyes were 26 eyes from 21 patients)
  2. *Chi-Square test, P < 0.05 means statistically significant
  3. aAmong postoperation amblyopia, 4 eyes are newly onset amblyopia with amblyogenic astigmatism (1 eye) or oblique astigmatism (3 eye)
