Table 4 Association between the occurrence of re-detachment and type of retinopexy for high risk subgroups (with primary PVR or silicon oil tamponade)

From: Comparative study of endolaser versus cryocoagulation in vitrectomy for rhegmatogenous retinal detachment

  Re-detachment Chi-squared Test
No (n) Yes (n) Yes (%) X2 p-value
Primary PVR (n = 93) Retinopexy
 Cryocoagulation 27 8 22.9 0.59 0.744
 Endolaser 32 7 18.0   
 Combined 14 5 26.3   
Primary silicone oil (n = 138) Retinopexy
 Cryocoagulation 49 10 17.0 0.47 0.791
 Endolaser 38 11 22.0   
 Combined 23 6 20.7
