    Sd-oct and plaquenil toxicity


    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.

    After five years of treatment, perform annual screenings, including an ocular examination, 10-2 threshold field testing, and one of the objective tests. In practical terms, SD-OCT is most widely available, and is very sensitive, so practitioners should look for subtle parafoveal abnormalities. Toxicity suspected and confirmed. SD-OCT is an objective test for toxicity that complements 10-2 visual field testing. 10-2 visual testing is probably more sensitive, but is heir to interpretational difficulties and variability not so much a problem with SD-OCT. Table 3 demonstrates that fields, mfERG, FAF, and SD-OCT can all show damage at a relatively early stage of hydroxychloroquine toxicity, but it is not predicable as to which test will be most definitive for any given individual. This makes a strong argument for using more than 1 modality routinely or at least for bringing in multiple modalities.

    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.

Previously described OCT findings in HCQ toxicity include loss of the external limiting membrane, disruption of the outer ellipsoid zone.

Applies to hydroxychloroquine oral tablet. Along with its needed effects, hydroxychloroquine the active ingredient contained in Plaquenil may cause some. As shown by this study and by Marmor and Melles, cases of early HCQ toxicity that display visual field changes attributable to HCQ toxicity in the setting of a ‘normal SD-OCT’ may in fact have early changes on SD-OCT as described in this report. We did not, however, observe any cases of HCQ retinopathy in which the visual field was normal but where morphological SD-OCT changes were detected. SD-OCT showed loss of the parafoveal inner/outer segment junction, thinning of the parafoveal outer nuclear layer, and a loss of the normal foveal depression, which is characteristic for hydroxychloroquine retinal toxicity Figure 3.

    Scared to take plaquenil. How can I be absolutely sure my. Scared to take plaquenil. How can I be absolutely sure my ophthalmologist knows how to detect retinal damage? I made the mistake of reading stuff about plaquenil online. Mostly it was people venting about how they saw ophthalmologists who didn't run the best/most comprehensive tests for eye damage and therefore let retinal damage go undetected.
