Purpose: To conduct an in vitro experimental study comparing the effectiveness of conventional silicone oil and heavy silicone oil against endophthalmitis-causing agents.
Materials and Methods: The antimicrobial activity of conventional silicone oil (RS OIL 5000) and heavy silicone oil (heavySil 1500) was tested. The antinicrobial effects of both silicone oils were determined by the growing capability of the microorganism.
Results: The number of Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans decreased to zero level at the second day of inoculation in heavy silicone oil. In conventional silicone oil, the microorganisms survived longer than in heavy silicone oil.
Conclusion: Heavy silicone oil seems to be more effective than conventional silicone oil against endophthalmitis-causing agents.
