The American Journal of Tropical Medicine and Hygiene
|September 1, 1984
Summary
Spider poisoning typically occurs via bite. This case details unusual poisoning through the eye from a smashed black widow spider, causing local and systemic effects.
Area of Science:
- Toxicology
- Ophthalmology
- Arachnology
Background:
- Spider envenomation usually results from a direct bite through the chelicera.
- Latrodectus hesperus, commonly known as the black widow spider, is a medically significant arachnid.
Observation:
- An unusual case of spider poisoning is reported.
- Poisoning occurred via conjunctival exposure to a fragment of a smashed black widow spider.
- The exposure route was through the patient's eye.
Findings:
- The patient experienced an immediate local reaction affecting the periorbital tissues.
- Systemic effects were observed following the ocular exposure.
- This suggests envenomation can occur through mucous membranes.
Implications:
- Highlights a rare but potential route for spider venom exposure.
- Underscores the importance of considering ocular exposure in suspected arachnid envenomations.
- May inform emergency protocols for eye injuries involving potential venomous arthropods.
