A well-recognized complication of silicone oil use is the development of band keratopathy. The keratopathy occurs when the silicone oil touches the endothelium and probably results from reduced fluid flow across the cornea with subsequent change in the pH.1 In some eyes with silicone oil, emulsification of the silicone oil occurs. This produces the tiny droplets of silicone oil that float freely, separated from the major body of the oil. The frequency of this occurrence appears to increase the longer the silicone oil is in the eye and may approach 100%.2 The presence of emulsified silicone oil droplets in the anterior chamber is not usually associated with keratopathy.3 We have recently seen a patient with silicone oil in the posterior chamber, which was well separated from his cornea by iris and by a posterior chamber lens, who developed emulsified silicone oil in the anterior chamber. The emulsified
