Incomplete posterior vitreous detachment despite vitrectomy with silicone oil tamponade

The fundamental step of a successful vitrectomy is posterior vitreous detachment induction; however, incomplete induction sometimes occurs. It may not be well seen barely by ophthalmoscopy examination, but emulsified silicone oil droplets act as the agent highlighting out the two natural retro-hyaloid spaces. The emulsified silicone oil droplets float according to gravity, but were entrapped over the pre-optic disc and the pre-macular bursa,...
