Abstract
Oxane HD is a mixture of silicone oil and a mixed fluorinated and hydrocarbonated olefin. The authors report a complication of Oxane HD as internal tamponade after removal of all visible heavy silicone oil. A 71-year-old man who underwent vitrectomy with Oxane HD presented with adherence of a residual bubble of Oxane HD in the macula after removal of all visible heavy silicone oil. In this patient OCT displayed an optical artifact due to the residual bubble, and fundus-related perimetry revealed a predominantly eccentric and relatively unstable fixation and very low macular sensitivity. After surgical removal of the residual bubble, metamorphopsia resolved, sensitivity improved as revealed by fundus-related perimetry, and fixation became predominantly central and more stable. The authors suggest a way to manage this rare complication of Oxane HD as internal tamponade after removal of all visible heavy silicone oil.
