Etiology and diagnosis of fungal postoperative endophthalmitis
Abstract:
Delayed infections after ocular surgery (especially cataract) are usually due to saprophytic contaminant fungi of relatively low pathogeneicity. About 20 different varieties of fungi have been cultured from such eyes. Thus, as far as the eye is concerned, there is no such thing as a harmless, benign fungus. Mycotic postoperative endophthalmitis is a distinct entity with a typical clinical picture, easily diagnosed once learned. Laboratory tests are often positive. Since the visual result is poor even if the eye is saved, prevention and early recognition are our primary concerns. In this regard, a recent episode of 12 infections from contaminated intraocular lens neutralizing solutions as well as other sporadic instances of fungal infection after lens implantation must be noted.
Insights
Fungal infections following eye surgery, particularly cataract procedures, can lead to poor visual outcomes. Early detection and prevention are crucial, as even low-pathogenicity fungi pose a significant risk to ocular health.
Area of Science:
- Ophthalmology
- Medical Mycology
Background:
- Delayed infections post-ocular surgery, especially cataract surgery, are frequently caused by contaminant fungi.
- Approximately 20 fungal varieties have been identified in infected eyes, indicating no fungus is truly benign in this context.
- Mycotic postoperative endophthalmitis presents a distinct clinical picture and can be diagnosed through laboratory tests.
Purpose of the Study:
- To highlight the risks associated with fungal contamination in ocular surgery.
- To emphasize the importance of early recognition and prevention of mycotic postoperative endophthalmitis.
- To note recent outbreaks linked to contaminated intraocular lens solutions.
Main Methods:
- Review of clinical cases and laboratory cultures of fungal infections after ocular surgery.
- Analysis of clinical presentation and diagnostic findings of mycotic postoperative endophthalmitis.
- Investigation of outbreaks associated with contaminated surgical materials.
Main Results:
- Saprophytic fungi, often of low pathogenicity, are common culprits in delayed post-surgical ocular infections.
- Poor visual prognosis is typical even when the eye is successfully treated.
- Contaminated intraocular lens neutralizing solutions have been implicated in recent infection clusters.
Conclusions:
- All fungi cultured from post-surgical eyes should be considered potentially harmful.
- Prevention strategies and prompt diagnosis are paramount for managing fungal endophthalmitis.
- Vigilance is required regarding sterile processing of intraocular lenses and associated solutions.
