Severe emulsification after combined use of a partially fluorinated alkane and silicone oil
1Department of Ophthalmology, Medical University of Lübeck, Germany. hhoerauf@ophtha.mu-luebeck.de
Purpose:
To present a case with accidental incomplete removal of a partially fluorinated alkane during a direct exchange with silicone oil and a subsequent severe emulsification of the silicone oil.
Case Report:
During a macular rotation procedure an incomplete exchange of perfluorohexylhexane (F6H6) with silicone oil occurred. Initial postoperative findings showed phase separation and exact visualization of the fundus. After a few days severe opacification of the mixture occurred, markedly reducing fundus visibility. The substances were removed immediately and analyzed by gas chromatography.
Conclusion:
The direct exchange between silicone oil and partially fluorinated alkane should be avoided. Their combined use as a simultaneous endotamponade can cause opaque separation.
