Two of the subfoveal PFCL bubbles were detected and confirmed by SD-OCT after pars plana vitrectomy and silicone oil removal at second month visit.. PFCL, perfluorocarbon liquid; SD-OCT, spectral domain optical coherence tomography.

This finding was confirmed using optical coherence tomography (OCT) (Figure 1).
ILM was dyed with brilliant blue and peeled via an ILM forceps, allowing more internal flexibility for transretinal aspiration of PFCL bubbles.. ILM, internal limiting membrane; PFCL, perfluorocarbon liquid.

During the third surgical session, after staining the ILM with brilliant blue, ILM peeling was performed in maculorhexis fashion (Figure 2).
All PFCL bubbles were aspirated through the silicone tip of the 23 G Flute cannula in a 'light touch' maneuver at the same locus, transretinally.. PFCL, perfluorocarbon liquid.

The subfoveal PFCL bubbles were passively aspirated using a 23 G silicone-tip Flute cannula directed toward the largest subretinal bubble in a light-touch maneuver (Figure 3).
(a) At the postoperative second-week visit of PFCL removal, some degree of IS/OS disruption secondary to possible PFCL toxicity was detected. (b) This IS/OS defect remained almost stabile at the end of 1-year follow-up. Some degree of epiretinal gliosis can be seen outside the ILM-peeling area.. ILM, internal limiting membrane; IS/OS, inner segment/outer segment; PFCL, perfluorocarbon liquid.

The OCT exam revealed inner segment/outer segment disruption at the 2-week follow-up (Figure 4(a)) and in the later follow-ups (Figure 4(b)), which led to a limited BCVA of 20/100 at the 1-year postoperative follow-up.
