    The preferential loss of photoreceptor IS/OS junction makes SD-OCT an ideal tool to identify early changes associated with Plaquenil retinal toxicity. Due to the capabilities of SD-OCT to enhance the structural assessment of the retina, it has allowed for the detection of early damage prior to funduscopic clinical findings. There are many other macula problems so patients using Plaquenil should have a baseline examination and testing to ascertain the health of the macula at initiation of therapy and allow periodic monitoring for early signs of macular toxicity, to lessen the risk of visual loss. Recommendations on Screening for Chloroquine and Hydroxychloroquine Retinopathy Retinal toxicity from chloroquine CQ and its analogue, hydroxychloroquine HCQ, has been recognized for many years. Chloroquine toxicity remains a problem in many parts of the world, but is seen less frequently in the United States where the drug largely has been replaced by HCQ.

    Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center.

    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. Lyons emphasizes the importance of annual screening and says that, although annual screening is recommended for everyone taking Plaquenil, it is imperative for people who have been taking the medication for more than 10 years, who have a higher incidence of retinal toxicity. Plaquenil-induced toxicity usually will not occur before five years of. Discussion. A risk factor for Plaquenil hydroxychloroquine retinotoxicity is a daily dose that exceeds 5.0 mg of drug per kg of body weight. The tool on the right simply calculates this threshold based on a patient’s real body weight. It’s important to understand that the daily dose is only one risk factor for plaquenil retinotoxicity.

    Hydroxychloroquine-Induced Retinal Toxicity - American. On examination, a telltale sign of hydroxychloroquine toxicity is a bilateral change in the retinal pigment epithelium of the macula that gives the commonly described appearance of a bull’s-eye. This is a late finding, however, and too late for screening to be useful.
