Silicone oil is one of the most common tamponade agents used after vitreoretinal surgeries.[1] However, its emulsification is a significant complication with adverse sequelae.[2] Factors causing emulsification have been examined and duration of silicone oil in the eye is found to have the strongest correlation.[3],[4] A 56-year-old diabetic lady was operated for left eye combined retinal detachment just before the COVID-19 pandemic and then lost to follow-up. She returned 18 months later with a hazy view due to silicone oil emulsification but a settled retina [Figure 1]a and [Figure 1]b. Her BCVA was 6/36, IOP 16 mmHg. OCT scans were remarkable for highly refractile dots in the vitreous, retina, RPE and choroid, akin to a 'starry sky,' and may even represent true migration of silicone oil vacuoles, rarely documented on imaging [Figure 1]c and [Figure 1]d.[5],[6],[7] Early removal of silicone oil may help in preventing emulsification.
