Summary
Corneal bee stings cause varied reactions, from severe pain and edema to mild irritation. Understanding bee venom toxins and allergens is key to managing these ocular injuries.
Area of Science:
- Ophthalmology
- Toxicology
- Immunology
Background:
- Corneal bee stings are rare but can cause significant ocular damage.
- Reactions to bee venom are complex, involving both toxic and immunologic mechanisms.
Purpose of the Study:
- To report three distinct cases of corneal bee sting injuries.
- To describe the clinical presentations and potential mechanisms of ocular damage from bee venom.
Main Methods:
- Case report analysis of three patients with corneal bee stings.
- Review of the known toxic and allergenic components of bee venom.
Main Results:
- Case 1: Severe pain, conjunctival chemosis/hyperemia, central corneal edema, reduced visual acuity.
- Case 2: Severe pain, conjunctival hyperemia, corneal infiltrate.
- Case 3: Minimal foreign-body sensation.
Conclusions:
- Corneal bee sting reactions exhibit significant variability.
- Bee venom components like melittin, apamin, formic acid, and phospholipase A likely contribute to the observed ocular effects.
