There are new screening modalities for early detection of asymptomatic hydroxychloroquine ocular toxicity.

    Toxicokinetics. Both chloroquine and hydroxychloroquine have excellent oral absorption and bioavailability. Both have a long and variable plasma elimination half-life because of a high volume of distribution, an extended mean residence time HCQ 1300 hours and CQ 900 hours and with about half the drug metabolites undergoing unmodified renal clearance. Mar 01, 2011 Hydroxychloroquine Plaquenil, Sanofi-Aventis remains widely used in the treatment of various rheumatologic disorders. A small percentage of patients exposed to hydroxychloroquine will develop irreversible, and potentially progressive, retinal toxicity for which no effective treatment exists. Hence, it is imperative that we become familiar with recognizing the spectrum of HVF and SD-OCT findings associated with Plaquenil retinal toxicity. Of note, SD-OCT, in combination with Humphrey visual field testing, is critical for the early detection of Plaquenil retinal toxicity.
