Factors having implications on re-retinal detachments after silicone oil removal.

Aim: To investigate factors having implications on re-retinal detachments (reRD) after silicone oil removal (SOR). Materials and Methods: A retroprospective study of 412 eyes (with attached retina after vitrectomy with silicone oil for rhegmatogenous RD) which underwent SOR was conducted and were followed up for six months after SOR. They were studied for various factors like encirclage, 360° retinopexy, oil emulsification at the time of SOR, duration of oil tamponade and previous retinal surgeries prior to SOR with their implications on reRD after SOR. Results: Encirclage, 360 laser barrage, both, emulsification of oil (P=0.021, P=0.001, P=0.001, P=0.001, respectively) were associated with lower risks of reRD after SOR whereas duration of tamponade (P=0.980) was not. Conclusion: Factors like encirclage, 360 retinopexy, their combination, oil emulsification reduced the incidence of re RD after SOR whereas duration of tamponade does not have statistical significant correlation with re RD after SOR.
