Summary

This study reports the first incidence of fluphenazine directly causing maculopathy due to retinal accumulation and toxicity. This finding is crucial for understanding drug-induced retinal damage in patients on antipsychotic medications.

Area of Science:

  • Ophthalmology
  • Pharmacology
  • Toxicology

Background:

  • Bilateral maculopathy in a 45-year-old female on long-term fluphenazine treatment for schizophrenia.
  • Visual acuity was significantly impaired in both eyes.

Observation:

  • Investigations including fluorescein angiography, color vision testing, and electrophysiological assessments confirmed retinal damage.
  • Maculopathy progression continued even after discontinuing fluphenazine medication.

Findings:

  • This case represents the first reported instance of fluphenazine directly causing maculopathy.
  • The drug's accumulation in the retinal pigment epithelium is believed to be the cause of its toxic effect.

Implications:

  • Highlights the potential for iatrogenic retinal toxicity from antipsychotic medications like fluphenazine.
  • Suggests a need for increased vigilance and monitoring for ocular side effects in patients using this drug.
  • Contributes to understanding drug-induced maculopathy beyond known environmental triggers.
