    A, Visual field 10-2, showing a white pattern deviation plot above a red gray-scale plot. B, A multifocal electroretinography mfERG trace array showing broad maculopathy and a clear ring of weak signals between the fovea and the more peripheral regions. Abstract. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. Either modality showed clear losses in moderate retinopathy. On repeated testing, the pattern deviation plots were somewhat more consistent than red fields in showing parafoveal damage. Conclusions With white 10-2 visual field hydroxychloroquine screening, the use of pattern deviation plots should be standard practice. Red testing appears to be more sensitive for early retinopathy but may be slightly less specific or consistent.

    Diagnosis of a toxic reaction was based on assessment of visual field findings according to the criteria outlined by Bernstein, 3 where acceptance of a case as a valid retinopathy requires as a minimum the presence and persistence of central or paracentral visual field scotomas to suprathreshold white stimuli and a duration of treatment of at least 9 months with a daily dose of hydroxychloroquine sulfate of 400 mg or less. Figure 3 Five consecutive 10-2 visual fields VFs with a white target. Notes VFs of a patient taking hydroxychloroquine at toxic doses who developed retinopathy. An incomplete annular scotoma in the zone from 2 to 8 degrees from fixation developed in the third VF. The AAO recommends that all patients beginning hydroxychloroquine therapy have a baseline evaluation, including a complete dilated examination and visual field test Amsler grid or Humphrey 10-2 perimetry. Other testing, such as color vision and fundus photography, is optional.
