Perfluoroperhydrophenanthrene (Vitreon) did not significantly alter chronic intraocular pressure (IOP) abnormalities when used as a retinal manipulator or tamponade. Its safety profile for IOP management is comparable to C3F8, SF6 gases, and silicone oil.

Area of Science:

  • Ophthalmology
  • Retinal Surgery
  • Vitreoretinal Interface

Background:

  • Intraoperative tools and postoperative tamponades are crucial in retinal surgeries.
  • Managing intraocular pressure (IOP) post-surgery is vital for successful outcomes.
  • Perfluoroperhydrophenanthrene (Vitreon) is a synthetic perfluorocarbon liquid with potential applications in retinal manipulation and tamponade.

Purpose of the Study:

  • To evaluate the incidence of chronic intraocular pressure (IOP) abnormalities after using perfluoroperhydrophenanthrene (Vitreon) as an intraoperative manipulator and/or postoperative tamponading agent.
  • To compare the IOP-related safety profile of Vitreon with traditional tamponading agents like C3F8 gas, SF6 gas, and silicone oil.

Main Methods:

  • A study involving 234 eyes where Vitreon was used as an intraoperative hydrokinetic retinal manipulator.

  • Postoperative follow-up assessed the use of C3F8 or SF6 gases, silicone oil, or Vitreon as tamponading agents.
  • Chronic intraoperative pressure abnormalities were defined as hypotony (IOP ≤ 5 mm Hg) or elevated IOP (IOP ≥ 25 mm Hg) at three or more postoperative visits.

    • Main Results:

    • Postoperatively, 12% of eyes (28/234) exhibited chronically elevated IOP, and 18% (41/234) had chronic hypotony.
    • No statistically significant difference in the incidence of abnormal IOP was observed among the groups using different tamponading agents.
    • The use of Vitreon, either intraoperatively or as a short-term tamponade, did not lead to a higher incidence of chronic abnormal IOP compared to silicone oil, C3F8, or SF6.

    Conclusions:

    • Vitreon can be safely employed as an intraoperative retinal manipulator and short-term tamponade without adversely affecting long-term intraocular pressure regulation.
    • The incidence of chronic hypotony and elevated IOP following retinal surgery is comparable regardless of whether Vitreon, silicone oil, C3F8, or SF6 is used as the tamponading agent.
