Refining the Removal of Perfluorocarbon Liquid Remnants Through Negative Staining With Vital Dyes.

The complete removal of perfluorocarbon liquid (PFCL) after complex vitreoretinal surgery can be a challenging task. However, it remains a crucial step to avoid several ocular complications associated with retained PFCL. In this report, the authors describe a simple and effective technique to highlight the presence of retained PFCL bubbles in the epiretinal space through negative staining with vital dyes.
