A 41-year-old man and 38-year-old woman presented for ocular examination. The visual acuity of the left eye was hand motions in both patients. Anterior segment examination showed “reverse pseudohypopyon” in the left eye, which was emulsified silicone oil migrating from the posterior chamber after a previous retinal detachment surgery (RDS). The silicone oil as an intraocular tamponade has been commonly used for repair of complicated retinal detachment. These cases highlight a possible complication of silicone oil and the importance of follow-up care.
