USING SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY IMAGING TO IDENTIFY THE PRESENCE OF RETINAL SILICONE OIL EMULSIFICATION AFTER SILICONE OIL TAMPONADE

Abstract

The authors have found small hyperreflective areas intraretinally, subretinally, and underneath epiretinal membranes on SD-OCT in eyes that have had silicone oil tamponade for a variety of indications. The authors have seen a similar appearance when silicone oil emulsification is examined in vivo. The authors conclude that the hyperreflective areas are likely (but not certain) to be very small bubbles of emulsified silicone. Further studies are required to determine the incidence, clinicopathologic, and functional significance of probable silicone oil emulsification and deposition within the retinal layers.
