Abstract:
A prospective in vitro study was conducted to investigate the potential for various perfluorocarbon liquids to support the growth of microbes, which may be introduced into these liquids as contaminants during intraocular surgery. Perfluorodecaline, perfluoro-noctane, and perfluorophenanthrene were tested for the growth of Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans by using tryptone soy broth, pancreatic digest of casein, and Sabouraud broth as culture media for up to 10 days. No microbial growth was observed in any of these perfluorocarbon liquids. Perfluorocarbon liquids do not promote microbial growth. Thus, they do not increase the risk of endophthalmitis in vitreoretinal surgery.
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.
