Silicone oil (SO) is a commonly used tamponading agent in retinal detachment surgeries. Inadvertent anterior migration of SO and complete anterior chamber (AC) oil fill in an aphakic or pseudophakic eye is occasionally encountered. This can cause secondary glaucoma with very high intraocular pressure and pain. In this scenario, an urgent silicone oil removal (SOR) is warranted. Since SO is buoyant, in the supine position, it tends to rise anteriorly. Hence, removal of SO trapped in the AC will invariably lead to further migration of oil from the posterior segment into the AC to replace the volume removed. Simultaneous replacement of AC volume is necessary to prevent this. We describe a modified technique of partial SOR that employs air to prevent recurrent migration of SO into AC.
