[Ocular burns caused by latex from manchineel trees]

Area of Science:

• Ophthalmology
• Toxicology

Context:

• Manchineel tree (Hippomane mancinella) latex is a potent irritant.
• Ocular exposure to plant-derived toxins presents significant clinical challenges.

Purpose:

• To assess the severity of ocular burns from manchineel tree latex exposure.
• To establish an effective therapeutic approach for these injuries.

Summary:

• A prospective study of 11 patients with ocular burns from manchineel tree latex.
• Findings include conjunctival erosions, corneal lesions (keratitis, ulcers), and periocular burns.
• All patients achieved full recovery within 15 days with appropriate treatment.

Impact:

• Highlights the ophthalmological risks associated with manchineel tree latex.
• Emphasizes the importance of immediate irrigation and antibiotic therapy for chemical eye injuries.
• Demonstrates the efficacy of prompt medical intervention in preventing long-term sequelae.
