Systemic gallium nitrate can cause vision loss and optic neuropathy. This case report highlights potential partial recovery with ferrous sulfate, emphasizing the need for ophthalmic monitoring.

Area of Science:

  • Ophthalmology
  • Toxicology

Background:

  • Gallium nitrate is used in treating hypercalcemia.
  • Systemic administration of medications can have ocular side effects.

Observation:

  • A 77-year-old man experienced bilateral visual loss and optic neuropathy after intravenous gallium nitrate.
  • Symptoms included central scotomas and diminished P2-wave amplitude on visual evoked potential.
  • The condition initially worsened despite oral corticosteroid therapy.

Findings:

  • Partial recovery of optic nerve function was observed after 12 months of oral ferrous sulfate.
  • Gallium nitrate-induced optic neuropathy may occur independently of other chemotherapeutic agents.

Implications:

  • Ophthalmic examinations are crucial for patients receiving gallium nitrate.

  • This case suggests a potential for partially reversible visual impairment.
  • Further research into the ocular toxicity of gallium nitrate is warranted.
