Use of 30 gauge needle to prevent hypotony during silicone oil removal

Silicone oil (SO) is used as an intraocular tamponade after complex vitreoretinal surgeries because of its properties such as transparency, inertness, high surface tension, and interfacial tension with water. The only disadvantage of SO tamponade is the need for a second surgery for its removal. However, there is a risk of ocular hypotony soon after the removal of the infusion cannula, especially in retinal vascular conditions, such as diabetic retinopathy. We hereby present a silicone oil removal (SOR) technique using a 30 G needle that prevents intraocular hypotony during SOR.
