    Multifocal ERG ring ratios provide a sensitive and objective method to detect ocular toxicity in patients taking hydroxychloroquine Plaquenil. In order to measure ring ratios, the average mfERG amplitude was calculated for each of five concentric rings of a 61-hexagon mfERG. Multifocal ERGs better quantify retinal toxicity than full-field ERGs. Below are mfERGs of several patients with Plaquenil toxicity. Plaquenil first affects small areas between 5-15 degrees from fovea eventually progressing to produce a ring scotoma. Figs. 47 and 48. Fig. 47. Because early toxicity changes can be revealed on SD-OCT, it is prudent to perform a baseline screening of patients taking Plaquenil. Multifocal ERG has the ability to detect early macular dysfunction, so it should be included as part of baseline screening. A maximum daily dose of Plaquenil of 5.0mg/kg real weight is recommended.

    She was previously treated with hydroxychloroquine (Plaquenil) 200mg bid (6.5mg/kg) for 10 years, which was stopped one year prior to presentation. She suffered from Sjogren syndrome and inflammatory arthritis and was currently treated with prednisone and methotrexate.

    The multifocal electroretinogram mfERG technique allows local ERG responses to be recorded simultaneously from many regions of the retina. As in the case of the full-field ERG, the ganglion cells contribute relatively little to the response, which originates largely from the outer retina. Multifocal Electroretinogram mf-ERG This test allows the detection of localized parafoveal or extramacular depression in early retinopathy 10, 15. This has similar sensitivity to visual fields and can provide objective confirmation of suspected paracentral field loss. Multifocal ERG has a consistent topographic distribution in the normal population. However, the summed amplitude of multifocal ERG can vary significantly among normal subjects. Therefore, topographic abnormalities via a three-dimensional distribution map are useful for the interpretation of multifocal ERG in diseased patients.
