Hydroxychloroquine visual field test


The most common tests to detect hydroxychloroquine toxicity have been visual acuity, visual fields (Amsler grid, automated visual field), color vision testing, full-field electroretinography (ERG), and multifocal electroretinography (mfERG).6, 7 Because of the localized nature of the defects, mfERG seems to be better than the full-field ERG in detecting early retinal toxicity. It is recommended that hydroxychloroquine be discontinued if ocular toxicity is suspected and the patient should be closely observed given that retinal changes (and visual disturbances) may progress. Guidelines recommend Humphrey visual field (VF) and spectral-domain OCT (SD-OCT) annually, along with multifocal electroretinography (mfERG) and fundus autofluorescence (FAF) as needed Plaquenil can cause retinal damage which can be reversed if caught early.
