Sir,
We read with great interest an article by Singh et al.[1] describing the sandwich technique using a combination of perfluoropropane and silicone oil for inferior retinal detachment. The authors have described a new technique for managing retinal detachments with inferior holes.
We have few queries for the technique:
It will be nice if authors could explain the technique of injecting gas. The authors injected gas through the infusion or through one of the ports. Then under direct visualization, while injecting silicone oil, how the gas escaped?[2] What authors suggest while using valved cannula?
In the aphakic eye was the iris diaphragm pushed forward or the anterior chamber was completely filled with gas at the end of surgery?[3]
Financial support and sponsorship
