Silicone oil opacification without emulsification: a rare complication following pars plana vitrectomy

We report a case of a young patient in his mid-20s who underwent retinal detachment surgery four years before. The patient was lost to follow-up for 4 years. At present, the patient presented to our centre with loss of vision in the operated eye. Examination revealed an oil-filled globe with no signs of oil emulsification. Instead, the oil had lost its transparency and had become opacified. The oil sample was removed and subjected to Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric analysis (TGA), and mass spectrometry analysis to ascertain the cause of oil opacification.
