    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.

    When this thinning is translated into an OCT map, a bulls-eye pattern of thinning is manifested, as shown in the image entitled "Time Domain OCT Map in Hydroxychloroquine Toxicity". The patient shown here is the same one shown in the image "Asymmetric Hydroxychloroquine Plaquenil Retinal Toxicity". The risk for retinal toxicity begins once the patient has used Plaquenil for five to seven years and/or has taken a cumulative dose of more than 1,000g. Patients with renal or hepatic dysfunction are at an increased risk of toxicity. 1 Other risk factors for retinal toxicity include short stature, obesity, advanced age and/or a pre-existing.

    It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects. Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress.

Our patient demonstrates the importance of using the new recommended screening tools for the detection of early hydroxychloroquine toxicity. 10-2 HVF, SD-OCT, autofluorescence, or mfERG might have detected the hydroxychloroquine retinal toxicity on the day of her presenting symptoms and possibly earlier, potentially limiting the amount of visual loss.

    Although hydroxychloroquine retinal toxicity is thought to be rare, recent studies suggest it may have a higher prevalence than previously recognized. A large study examining patients with more than 5 years of HCQ use were evaluated with 10-2 visual fields or spectral-domain optical coherence tomography SD OCT. Previously described OCT findings in HCQ toxicity include loss of the external limiting membrane, disruption of the outer ellipsoid zone, parafoveal thinning of the outer nuclear layer and RPE damage. 6,7,10 Despite these various changes, numerous studies have supported the notion that relative “foveal resistance” is common in HCQ toxicity, as demonstrated by preservation of the subfoveal outer retinal layers, accounting for the intact central visual acuity that can be seen even in.

    Ideal Body Weight for Calculating Hydroxychloroquine Dosage The usual hydroxychloroquine dose that is prescribed is 400 mg/day. For this dosage, any woman with an ideal body weight less than 135 pounds would be in the toxic dose range. As one can see, the height that corresponds to an ideal body weight of 135 pounds varies across the formulas.
