When a vitrectomy was not performed, 93 % of cases were treated by buckling. Here are the different techniques of buckle. It appears that in general, most surgeons use segmental buckle.

It can be noticed that the buckling technique varies according to the stage of PVR. More cases without buckle for stage 0.

Failure rate of buckle according to the stage of PVR when no vitrectomy is performed.  Buckling technique appears to be very relevant for stages 0 and A  In contrast, for PVR stage C1, the failure rate of 13% is not acceptable and the procedure No Vitrectomy + Buckling does not suit for this situation.

As far as retinopexy is concerned, when no vitrectomy is performed, it can be noticed that most surgeons have recourse to Cryo reinforced or not by Focal laser. Only 6% use transpupillary Focal Laser alone and 1% 360° Laser retinopexy.

When no vitrectomy is performed, gas tamponade is performed in 88% of the cases. Air and SF6 are mainly used. Only 12% of cases are treated without gas tamponade.

The more advanced the PVR, the less frequently cases are treated without tamponade.  Surprisingly, in more advanced stages of PVR, surgeons tend to use air rather than other gases such as C3F8.

When looking at the distribution according to the PVR, nothing obvious appears.

Besides, there is no significant difference between drainage and no drainage concerning the failure rates.
