Let’s now focus on specific RDs such as Large and Giant tears and Macular Holes.

When studying only G and L tears with choroidal detachment and hypotony excluded and all PVR stages grouped together, it is shown that performing a vitrectomy leads to far better results than treating the case without vitrectomy.

When looking only at stage A, the result above is found as well. It is therefore recommended to perform a vitrectomy for Large and Giant tears.

When going back to all PVR stages, it appears that a flow control pump is more efficient than a vacuum pump in respect of the failure rate. However the difference is not significant.

For G and L tears, choroidal detachment and hypotony excluded and all PVR stages grouped together, it is shown that cases operated without buckle have better results than cases with buckle. This is statistically significant.

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

The same conclusions can be drawn for macular holes.

As well as for vitrectomy machine choice.

In summary, we can conclude that, in absence of aggravating factors, for Giant or Large tears, vitrectomy leads to better results than not performing a vitrectomy. Moreover, not performing any buckle improves even more the surgical outcome. For macular hole we should select vitrectomy and gas injection.
