Background:
Fungal keratitis shows a variable clinical picture and is therefore often diagnosed only late. Fungi in general are quite resistant organisms, and in addition treatment is difficult due to limited and specially manufactured medications.
Material And Methods/Results:
We describe the unfavourable outcome in a young female patient with keratitis due to fusarium that ended - despite extensive medical and surgical treatment - in enucleation. Histologic examnination of the enucleated globe revealed massive (post-)inflammatory changes throughout the anterior segment but only few persistent fungal elements that were found in the lens capsule (after phacoemulsification) and the peripheral Descemet's membrane.
Conclusion:
Fungus as the pathogenic agent in therapy-resistent keratitis should be included in the differential diagnosis as early as possible. Should surgical interventions become necessary, a keratoplasty as large as possible and removal of the lens capsule should be considered in order to eliminate potential reservoirs for the causative organism.
Insights
Fungal keratitis, often diagnosed late due to varied symptoms, can lead to severe outcomes like enucleation. Early diagnosis and aggressive surgical intervention, including large keratoplasty and lens capsule removal, are crucial for treating resistant fungal eye infections.
Area of Science:
- Ophthalmology
- Medical Mycology
Background:
- Fungal keratitis presents with diverse clinical signs, often leading to delayed diagnosis.
- Fungi are inherently resistant organisms, complicating treatment due to limited medication options.
Purpose of the Study:
- To highlight the challenges and unfavorable outcomes in treating severe fungal keratitis.
- To emphasize the importance of early diagnosis and comprehensive treatment strategies for fungal eye infections.
Main Methods:
- Case report of a young female patient with Fusarium keratitis.
- Detailed description of extensive medical and surgical interventions.
- Histopathological examination of the enucleated globe.
Main Results:
- The patient underwent enucleation despite extensive treatment for Fusarium keratitis.
- Histology revealed significant post-inflammatory changes and minimal fungal elements in the lens capsule and Descemet's membrane.
Conclusions:
- Fungal infections must be considered early in therapy-resistant keratitis cases.
- Large-diameter keratoplasty and removal of the lens capsule are recommended surgical approaches to eradicate fungal reservoirs.
