[Pathogenesis of secondary glaucoma after intraocular silicone oil administration].
BACKGROUND
There are various causes of increasing ocular tension after vitrectomy and intraocular silicone oil filling; it is reported on a new type of postoperative secondary glaucoma.


METHODS
A 56-year-old man with flat anterior chamber and secondary glaucoma after vitrectomy and intraocular silicone oil filling was examined; only the transpupillary inspection of the posterior surface of the iris with the three mirror contact glass yielded the decisive reference to the pathogenesis of the glaucoma.


RESULTS
The secondary glaucoma was caused by small perfluoroctane bubbles blocking up Ando's peripheral iris coloboma.


CONCLUSIONS
In case of an unclear pathogenesis of secondary glaucoma after vitrectomy and fluid/perfluoroctane/silicone oil exchange among others a blockade of Ando's peripheral coloboma by small perfluoroctane bubbles should be considered as a cause of increased intraocular tension.
