Hydroxychloroquine retinopathy risk is low with proper dosing. However, this case report highlights potential maculopathy in an elderly rheumatoid arthritis patient, even within guidelines, suggesting increased susceptibility in older individuals.

Area of Science:

  • Ophthalmology
  • Rheumatology
  • Clinical Pharmacology

Background:

  • Hydroxychloroquine is commonly prescribed for rheumatoid arthritis.
  • Established guidelines aim to minimize ocular toxicity, specifically retinopathy.
  • Elderly patients may represent a vulnerable population for drug-induced side effects.

Observation:

  • A case report of an elderly patient with rheumatoid arthritis is presented.
  • The patient developed bilateral maculopathy.
  • The condition occurred despite adherence to recommended hydroxychloroquine dosage.

Findings:

  • The observed maculopathy was presumed to be secondary to hydroxychloroquine.
  • This suggests that even within therapeutic guidelines, ocular toxicity can occur.

  • Elderly patients' retinal pigment epithelium might be more susceptible to hydroxychloroquine toxicity.

    • Implications:

    • Reinforces the need for vigilant monitoring of elderly patients on hydroxychloroquine.
    • Suggests potential modifications to hydroxychloroquine dosing or monitoring protocols for geriatric populations.
    • Highlights the importance of considering drug-induced maculopathy in elderly patients presenting with visual disturbances.
