    American Academy of Ophthalmology recommendations for screening for hydroxychloroquine HCQ retinopathy advise objective measures, such as spectral-domain optical coherence tomography SD-OCT and multifocal electroretinography mfERG along with visual fields. Today it is recommended that every single person on Plaquenil get a visual field 10-2 test, plus one of the three other highly sensitive screening tests the FAF fundus autofluorescence imaging, the SD-OCT spectral domain optical coherence, or the multifocal electroretinogram mfERG,” Thomas says. The wider visual field tests, such as 24-2, are not sufficiently sensitive to screen the parafoveal region and may miss small scotomas. These tests are therefore not recommended as screening tools. Nevertheless, it is doubtful that the 10-2 visual field test is sufficiently effective as a screening tool. In many cases, the diagnosis of HCQ retinal toxicity was delayed when visual field tests were dismissed as “nonspecific.”

    Although the incidence of macular toxicity is infrequent with Plaquenil use (at a dosage of 200mg or 400mg q.d.), its visual impact can be devastating. Her rheumatologist instructed her to undergo a baseline ocular examination prior to initiating Plaquenil (hydroxychloroquine, Sanofi-Aventis) therapy.

One year later, a 10-2 HVF was obtained that showed dense paracentral scotomas bilaterally Figure 2, despite normal visual acuity, Amsler grid, and color vision testing. Upon the detection of the visual field defects, the hydroxychloroquine was stopped.
