Summary

Radiation retinopathy, a delayed complication of radiation therapy, caused vision loss in a patient treated for nasopharyngeal carcinoma. Laser photocoagulation improved her vision, highlighting a potential treatment for this ocular condition.

Area of Science:

  • Ophthalmology
  • Radiation Oncology
  • Oncology

Background:

  • Radiation retinopathy is a significant ocular complication following radiation therapy for various diseases.
  • It is characterized by slow progression and delayed onset, affecting retinal blood vessels.

Observation:

  • A 49-year-old female presented with a 2-year history of progressive blurred vision.
  • Her best corrected visual acuity was 0.02 (right eye) and 0.06 (left eye).
  • Fundus examination revealed hard exudates, retinal hemorrhage, and macular edema in both eyes.

Findings:

  • The patient had a history of nasopharyngeal carcinoma treated with irradiation 11 years prior.
  • She had no history of diabetes mellitus or other systemic diseases.
  • Laser photocoagulation treatment resulted in improved visual acuity to 0.2 (right eye) and 0.3 (left eye) after 1 year.

Implications:

  • This case highlights radiation retinopathy as a delayed ocular complication after nasopharyngeal carcinoma treatment.
  • Laser photocoagulation demonstrates potential efficacy in managing vision impairment caused by radiation retinopathy.
  • Early recognition and intervention are crucial for managing radiation-induced ocular complications.
