Dear Editor,
We read with great interest the article titled "Factors having implications on re-retinal detachments after silicone oil removal" by Nagpal et al. [1]
Silicone oil removal is generally done using two ports (one for infusion and the other for egress of oil using a 18/19-G needle) or a single-port infusion with a limbal incision in aphakic eyes. [2],[3] Routinely we resort to 20-G or 23-G 2-port oil removal nowadays in our practice. Three port silicone oil removal is necessarily needed when there is a need for associated procedure like epiretinal membrane or need for additional LASER and need not be done as a routine as practised in this study. A two-port silicone oil removal is generally sufficient and less invasive.
The factors for retinal re-detachment (development of new break, opening up of existing break due to PVR, accidental trauma/instrument touch while removal of silicone oil) after removal of silicone oil have not been elaborated. We feel that these reasons might also have a bearing on the outcome.
It is not readily apparent from the study if the silicone oil used was exclusively normal density (1000 cs) or had also included heavy silicone oil as the indications for the two are different and hence may impact the outcome in terms of anatomical attachment of retina. [4]
Emulsified oil losing its endotamponade action is the hypothesis in consideration. We feel that, if, average duration of patients undergoing oil removal in both emulsified and non emulsified oil, are compared for statistical significance, the data may reveal interesting findings rather than comparing duration range of 3-6 months and more than 6 months.
We agree with authors' findings that a combination of encirclage and 360 degree endolaser favor a good outcome in terms of retinal attachment.
