Summary

Perfluoro-n-octane liquid did not affect rabbit corneal endothelial permeability to inulin and dextran. This indicates no toxicity, even with short-term or longer-term exposure, suggesting safety for ophthalmic use.

Area of Science:

  • Ophthalmology
  • Corneal Physiology
  • Ocular Toxicology

Background:

  • Perfluorocarbons are used in ophthalmology.
  • Potential corneal toxicity is a concern.

Purpose of the Study:

  • To investigate the effects of perfluoro-n-octane on rabbit corneal endothelial permeability.
  • To assess the safety of perfluoro-n-octane for ocular tissues.

Main Methods:

  • In vitro and in vivo exposure of rabbit corneas to perfluoro-n-octane.
  • Measurement of corneal endothelial permeability to inulin and dextran.

Main Results:

  • Perfluoro-n-octane did not alter corneal endothelial permeability.
  • No changes were observed after short-term (10 minutes) or sub-chronic (1 week) exposure.

Conclusions:

  • Perfluoro-n-octane exhibits no toxicity to the corneal endothelium.
  • The substance is safe for potential intraoperative or postoperative ocular applications.
