title: Pupillary block glaucoma due to residual perfluoro-decalin.
abstract: Perfluorocarbon liquids are used in vitreoretinal surgery and should be removed by the end of surgery. Removal is not always achieved and a few cases of complications resulting from perfluorocarbon liquid residues have been reported. The authors report a unique case of pupillary block glaucoma resulting from perfluoro-decalin residue in the anterior chamber that blocked a surgical coloboma of the iris at the 6-o'clock position. The perfluoro-decalin residue dissolved spontaneously with antiglaucoma treatment and no surgical intervention was needed. When perfluorocarbon liquids are used during pars plana vitrectomy, the possibility of silicone-induced pupillary block in the presence of an inferior iris coloboma should not be overlooked.
