Researchers recently reported on early optical coherence tomography OCT abnormalities due to HCQ toxicity that may develop through normal visual field VF testing. They found that patients with high-risk HCQ exposure and normal VF testing may develop subtle but characteristic OCT. In the United States, hydroxychloroquine is most often used for its anti-inflammatory effects in rheumatology and dermatology. Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine.

One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine Plaquenil, a chloroquine derivative. It is used to treat many diseases including malaria, rheumatoid arthritis and systemic lupus erythematosus. To detect chloroquine toxicity, the American Academy of Ophthalmology recommends performing fundus examinations, 10-2 automated visual fields, and at least one objective test multifocal electroretinography mfERG, fundus autofluorescence imaging, or spectraldomain optical coherence tomography SD-OCT. 1 By contrast, Amsler grid testing. Plaquenil induced retinal toxicity is reversible if detected early and plaquenil dosage altered or the medication discontinued. Even suspicious early plaquenil toxicity warrants communication with the patient’s treating physician, and meaningful coordination of care would include a report even if the findings are normal.
