Area of Science:

  • Ophthalmology
  • Toxicology
  • Dermatology

Background:

  • Caterpillars possess toxic substances affecting human tissues, particularly eyes and mucous membranes.
  • Ocular lesions from caterpillars are rare but can be severe, necessitating prompt clinical evaluation.

Observation:

  • A 7-year-old child experienced toxic keratoconjunctivitis and a rash after caterpillar contact.
  • A 17-year-old patient developed toxic iridocyclitis due to a caterpillar hair in the anterior chamber.

Findings:

  • Ocular symptoms in the child resolved with ocular washings and topical/systemic antihistamines.
  • The 17-year-old's iridocyclitis, characterized by lymphoplasmacytic infiltrate with eosinophils, resolved after surgical removal of the caterpillar hair.

Implications:

  • Early and thorough ocular irrigation is crucial for managing caterpillar-induced toxic keratoconjunctivitis.
  • Surgical intervention may be necessary for severe ocular inflammation caused by foreign bodies like caterpillar hairs.
  • Understanding caterpillar toxins is vital for effective treatment of ocular and dermatological conditions.
