Area of Science:

  • Ophthalmology
  • Marine Biology
  • Toxicology

Background:

  • Corneal foreign bodies can lead to significant visual impairment.
  • Marine environments pose unique risks for ocular trauma and infection.

Observation:

  • A 39-year-old female scuba diver presented with acute right eye pain and blurred vision post-dive.
  • Examination revealed superficial corneal foreign bodies and adjacent infiltrates, consistent with coral exposure.

Findings:

  • The keratitis was attributed to direct contact with red coral, likely involving nematocyst toxins.
  • Histological examination suggested hypersensitivity reactions (Type I and IV) as a potential mechanism.

Implications:

  • This case highlights a rare form of keratitis resulting from marine environmental exposure.
  • Prompt diagnosis and prolonged corticosteroid therapy are crucial for managing coral-induced ocular injuries.
