Summary
Bluebottle stings can cause crystalline keratopathy in the cornea. Early debridement of corneal crystals following bluebottle envenomation aids rapid healing and symptom resolution.
Area of Science:
- Ophthalmology
- Toxicology
Background:
- Bluebottle envenomation of the cornea is a rare occurrence.
- Ocular injuries from marine encounters require prompt and effective management.
Observation:
- A patient presented with crystalline deposits and epithelial defects after a bluebottle sting.
- Initial first aid included hot shower and methoxyflurane for pain management.
- Slit-lamp examination revealed crystalline deposits and pseudodendritiform epithelial defects.
Findings:
- Corneal debridement successfully removed crystalline material.
- Histopathology showed irregular, nonrefractile crystals with squared edges.
- Raman spectroscopy suggested a calcium-based composition of the corneal crystals.
Implications:
- Early corneal debridement is crucial for managing bluebottle envenomation.
- This intervention can lead to rapid visual recovery.
- Understanding the nature of corneal crystals aids in treatment strategies.
