Strategy in RRD with PVR

Left Right
Concerning specifically stage C1, when choroidal detachment and hypotony are excluded, no significant difference appeared for the effective failure rate between no vitrectomy and vitrectomy.

Concerning specifically stage C1, when choroidal detachment and hypotony are excluded, no significant difference appeared for the effective failure rate between no vitrectomy and vitrectomy.

The differences are still not significant between no vitrectomy and vitrectomy performed with flow control pump although the failure rate is three times lower with a flow control pump. The absence of statistical significance is due to the low numbers involved : only 93 cases without vitrectomy and 100 with flow control vitrectomy for PVR stage C1.

For PVR stage C1, equatorial holes and normal tears, without choroidal detachment and hypotony, tamponade performed with gas leads to an true failure rate less than half of that with silicone tamponade. Once again, due to the small number of cases in this category, this difference is not high enough to be significant.

As far as buckle is concerned, cases where no buckling was performed buckle appeared to develop fewer failures than cases operated with buckling.

Let’s now focus on choroidal detachment and hypotony cases. All PVR stages are grouped together in order to obtain sufficient numbers to obtain significant p values. Concerning vitrectomy, it is obvious that performing one provides better result than not performing one. This is highly significant at the level of 0.15%.

The results concerning the type of tamponade do not show a statistically significant difference between gas and silicone tamponade for effective failure rate. However, once again, it may be a better strategy to have recourse to a gas tamponade since this leads to a far lower rate of remaining silicone.

Finally, as far as retinopexy is concerned, no obvious conclusion can be drawn from the comparison of the failure rates between cryo and focal laser since there is no statistically significant difference.

As a summary, we can conclude that, in absence of aggravating factors, and when a stage C1 is observed, the best strategy is to perform a vitrectomy if your machine has a peristaltic pump with gas injection.
