Insights

Perfluorocarbon liquids, used in eye surgery, do not support microbial growth. This finding indicates they do not increase the risk of endophthalmitis, a serious eye infection.

Area of Science:

  • Ophthalmology
  • Microbiology
  • Biomaterials Science

Background:

  • Perfluorocarbon liquids are utilized in intraocular surgery.
  • Contamination of these liquids with microbes is a potential risk.
  • Endophthalmitis is a severe post-operative complication.

Purpose of the Study:

  • To evaluate the potential of perfluorocarbon liquids to support microbial growth.
  • To assess the risk of microbial contamination in intraocular surgery using these liquids.

Main Methods:

  • Prospective in vitro study.
  • Tested perfluorodecaline, perfluoro-noctane, and perfluorophenanthrene.
  • Inoculated with Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans.
  • Utilized tryptone soy broth, pancreatic digest of casein, and Sabouraud broth.
  • Incubation for up to 10 days.

Main Results:

  • No microbial growth was observed in any tested perfluorocarbon liquids.
  • The tested perfluorocarbon liquids demonstrated no capacity to support microbial proliferation.

Conclusions:

  • Perfluorocarbon liquids do not promote microbial growth.
  • Their use in vitreoretinal surgery does not appear to increase the risk of endophthalmitis.

Microbial Growth Measurement: Indirect Methods

Estimating microbial growth is essential for understanding population dynamics and environmental adaptations. Indirect methods provide valuable insights by measuring parameters such as turbidity, metabolic activity, and biomass, enabling efficient and reproducible assessments.During exponential growth, microbial cells scatter light proportionally to their biomass, a principle used in turbidity measurements. About one million cells per milliliter produce detectable scattering, which a...
