Radiation therapy can cause temporary corneal stem cell dysfunction, leading to conjunctivalization. Medical treatment resolved abnormalities, though stem cell function did not fully recover, suggesting conservative management is preferred over surgery.

Area of Science:

  • Ophthalmology
  • Radiation Oncology

Background:

  • Radiation therapy can induce corneal and conjunctival abnormalities.
  • Corneal stem cell dysfunction is a known complication, potentially reversible after radiation cessation.

Observation:

  • A 44-year-old man developed corneal epithelial abnormality and inflammation post-radiation for maxillary cancer.
  • Symptoms included ocular pain, vision loss, and conjunctival epithelialization of the cornea.

Findings:

  • Cytology revealed goblet cells and intraepithelial lymphocytes on the cornea.
  • Corneal abnormalities resolved with artificial tears and antibiotic ointment within 4 months.
  • Palisades of Vogt did not recover at 1-year follow-up.

Implications:

  • This case highlights radiation-induced temporary stem cell dysfunction causing corneal conjunctivalization.
  • Conservative medical management should be prioritized over surgical intervention for such cases.
  • While limbal stem cell function may not fully recover, non-surgical options can be effective.
