Postoperative chronic pressure abnormalities in the vitreon study.


Perfluoroperhydrophenanthrene (Vitreon) was used as an intraoperative hydrokinetic retinal manipulator, followed by C3F8 or SF6 gases, silicone oil, or Vitreon as postoperative tamponading agents in 234 eyes. Two chronic intraoperative pressure abnormalities were defined: hypotony (5 mm Hg or less) and elevated intraocular pressure (IOP) (25 mm Hg or more at three or more postoperative visits). Postoperatively, 28 eyes (12%) had chronically elevated IOP, and 41 (18%) had chronic hypotony. There was no significant difference in the incidence of abnormal IOP among the groups of eyes in which the various tamponading agents had been used. In particular, the use of Vitreon as an intraoperative tool or as a short-term tamponade did not affect the incidence of chronic abnormal IOP any more than did the use of silicone oil, C3F8, or SF6 as tamponading agents.
