Corneal sea nettle stings can cause severe eye inflammation and high intraocular pressure, potentially leading to long-term complications like glaucoma. Prompt treatment is crucial for managing these jellyfish sting injuries.

Area of Science:

  • Ophthalmology
  • Marine Toxicology
  • Etiology of Ocular Inflammation

Background:

  • Corneal stings from the sea nettle jellyfish (Chrysaora quinquecirrha) in the Chesapeake Bay typically result in brief, self-limiting eye injuries.
  • These jellyfish stings are usually painful but resolve within 24 to 48 hours.

Observation:

  • Five patients presented with severe and prolonged iritis (inflammation inside the eye) and elevated intraocular pressure following corneal sea nettle stings.
  • Clinical follow-up ranged from 2 to 4 years to assess the long-term effects of these ocular injuries.

Findings:

  • All patients experienced decreased visual acuity, iritis, and significantly increased intraocular pressure (32-48 mmHg).
  • While iritis resolved within 8 weeks with topical corticosteroids, elevated intraocular pressure required beta blockers and carbonic anhydrase inhibitors.

  • Persistent complications included mydriasis (pupil dilation), decreased accommodation, peripheral anterior synechiae, iris transillumination defects, and one case of chronic unilateral glaucoma.

    • Implications:

    • Although typically self-limited, sea nettle venom can induce severe ocular inflammation and potentially lead to chronic eye conditions such as glaucoma.
    • This study highlights the importance of recognizing and managing severe ocular manifestations of jellyfish stings, as long-term sequelae can occur.
