[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.
Materials And 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.
