    Is retinal toxicity from plaquenil reversible


    Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. In the United States, hydroxychloroquine is most often used for its anti-inflammatory effects in rheumatology and dermatology.

    Plaquenil is an extremely safe medication but retinal and corneal side effects are possible. Unfortunately, the retinal side effects are largely irreversible and can lead to vision loss. So, it is critical to detect early retinal toxicity in the hopes of limiting the extent of visual loss. This condition does not cause symptoms and is reversible with cessation of the medication. The finding of corneal verticillata bares no correlation with retinal toxicity and is not an indication to stop the medication. The hallmark of hydroxychloroquine toxicity is bilateral pigmentary retinopathy. Patients with early retinal findings are often asymptomatic despite having subtle paracentral scotomas. These epithelial changes arise due to precipitation of the drug, typically forming a whorl-like pattern that is reversible with drug cessation. These changes are generally regarded as being of no visual significance, although some patients do report haloes. The presence of corneal verticillata does not correlate with retinal toxicity.

    While early toxicity may be asymtomatic, patients with more advanced stage of toxicity may complain of color vision changes or paracentral scotomas. Its toxic effects on the retina are seen in the macula.

  5. The reader's question and comment prompted me to do a little more research on the question of whether plaquenil toxicity was reversible which led me to the results of this study, which was published in JAMA Opthamology Jan 2011-- the same month and year as the Sjogren's Syndrome Foundation article was published. The study authors concluded.

    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. Several authors have questioned the utility of screening for hydroxychloroquine toxicity given the low yield, high cost, and the difficulty in diagnosing the condition early enough to prevent damage. 43–46 Nevertheless, toxicity does occur, and if retinal and functional changes are detected early, severe visual impairment can be averted. 47, 48 Use of static perimetry through the vertical meridian with a red test object may be the best method to detect an early paracentral scotoma. 49. The American Academy of Ophthalmology has published several dosing and screening recommendations for hydroxychloroquine to avoid potential retinal toxicity, yet some patients still experience permanent vision loss resulting from hydroxychloroquine retinopathy due to improper dosing of the drug and improper screening.
