Summary
Accidental exposure to Atropa belladonna wood caused a patient to experience fixed mydriasis (pupillary dilation). Symptoms resolved within three days, highlighting a less-known source of alkaloid toxicity.
Area of Science:
- Ophthalmology
- Toxicology
- Botany
Background:
- Atropa belladonna alkaloids are known for causing pupillary dilatation.
- The wood of Atropa belladonna contains a higher alkaloid concentration than its fruit.
Observation:
- A patient presented with a foreign body sensation in the eye after wood chopping.
- Ophthalmic examination revealed fixed mydriasis and reduced visual acuity.
Findings:
- The patient's symptoms were attributed to a splinter of Atropa belladonna wood.
- Pupillary size and visual acuity normalized within three days of the incident.
Implications:
- Atropa belladonna wood is a significant source of toxic alkaloids.
- Accurate patient history is crucial for diagnosing accidental mydriasis from plant exposure.
