    Chloroquine retinopathy, a serious side effect of rheumatoid arthritis treatment, can manifest years after stopping the drug. This condition is dose-related, irreversible, and requires medical attention.

    Area of Science:

    • Ophthalmology
    • Rheumatology
    • Pharmacology

    Background:

    • Chloroquine is a medication historically used for rheumatoid arthritis.
    • Chloroquine retinopathy is a known iatrogenic complication.
    • Delayed onset of retinopathy is a concern.

    Observation:

    • A patient developed chloroquine retinopathy 5 years after discontinuing chloroquine for rheumatoid arthritis.
    • The patient presented with decreased visual acuity.
    • Retinal findings were consistent with chloroquine retinopathy.

    Findings:

    • Chloroquine retinopathy is dose-dependent and largely irreversible.
    • The condition can be progressive once characteristic findings emerge.
    • Delayed onset, though rare, is possible.

    Implications:

    • Ophthalmologists and medical professionals must be aware of the potential for very delayed chloroquine retinopathy.
    • Early detection and monitoring are crucial for managing patients on long-term chloroquine therapy.
    • This highlights the importance of long-term surveillance for iatrogenic conditions.
