    It is generally well tolerated, but retinopathy is a concern. Retinopathy is rare, but is sight threatening, generally irreversible and may progress even after cessation of therapy. Although a number of risk factors have been proposed (such as duration of therapy and cumulative dose), the many exceptions (e.g.

    Cein angiography, full-field ERG, and electro-oculogram are not considered to be helpful.1-3 mfERG is a sensitive, objective, and reproducible test for detecting hydroxy-chloroquine toxicity. Several drugs taken in high doses or for long periods of time can cause retinal degeneration with pigmentary changes. Multifocal ERGs better quantify retinal toxicity than full-field ERGs. Following are mfERGs of a patient with Plaquenil toxicity displayed with b-wave, P1, amplitudes translated to a color scale. Plaquenil first affects areas between 5 and 15 degrees from fovea, eventually progressing to produce ring scotomas Fig. 32.21. Hydroxychloroquine is in a class of drugs called antimalarials. It is used to prevent and treat acute attacks of malaria. It is also used to treat discoid or systemic lupus erythematosus and rheumatoid arthritis in patients whose symptoms have not improved with other treatments.

    Novel technologies such as optical coherence tomography (OCT), fundus autofluorescence (FAF) and multifocal electroretinogram (mf ERG) may provide the earliest structural and functional evidence of toxicity in these stages. Retinopathy on low-dose HCQ, or no retinopathy after a very large cumulative dose of HCQ) highlight our limited understanding of the disease process.

  3. The primary value of fundoscopy is not for screening for toxicity but for documentation of other retinal pathology. Tests which are no longer recommended are the Amsler grid test, colour vision tests, fundus photograph, time-domain OCT, fluorescein angiography and full-field ERG as they are not sensitive enough to detect early signs of toxicity.

    At this point, full-field ERG should be considered to exclude diffuse photoreceptor loss. SUMMARY. Hydroxychloroquine is an effective and relatively safe drug that can cause retinal toxicity in a minority of patients. Early diagnosis is important to stop treatment and prevent possible further damage. Abstract. Purpose To examine the electroretinographic findings derived by full-field electroretinography ERG and multifocal electroretinography mfERG in patients taking HCQ for different periods of time, including those without clinically visible evidence of toxicity. Full Field ERG/EOG measures the entire retina as one unit. It is not sensitive to early toxic changes; 2 it only shows abnormalities in late chloroquine or hydrochloroquine toxicity. 1 These tests help judge how severe or widespread the damage is once toxicity has been established. 1
