Persistent anterior chamber silicone oil and myopia

A 60-year-old man experienced a marked unilateral myopic shift of 20 diopters following attempted removal of intravitreal heavy silicone oil used in the treatment of inferior proliferative vitreoretinopathy following retinal detachment. Examination revealed heavy silicone oil adherent to the corneal endothelium and forming a convex interface with the aqueous, obscuring the entire pupil. Surgical intervention was required to restore visual acuity. The case highlights the potential ocular complications associated with silicone oil migration into the anterior chamber, including corneal endothelial decompensation and a significant increase in myopia
