    Her rheumatologist instructed her to undergo a baseline ocular examination prior to initiating Plaquenil (hydroxychloroquine, Sanofi-Aventis) therapy. Toxic maculopathy associated with chloroquine use was first documented in the literature five decades ago.1 In the United States, Plaquenil––an analog to chloroquine––is used to treat a variety of conditions, including rheumatoid arthritis, lupus and several distinct inflammatory disorders.

Early signs visual field defects on 10-2 HVF usually paracentral, perifoveal and parafoveal thinning of the retina with loss of the inner/outer segment junction on SD-OCT, increased or decreased signal on autofluorescence, central/paracentral ERG depression on mfERG, +/- changes on Amsler grid, +/- subtle RPE changes, +/- decreased color vision When allowed to advance, hydroxychloroquine retinal toxicity leads to loss of up to three visual functions acuity, peripheral vision and night vision. Signs. On examination, a telltale sign of hydroxychloroquine toxicity is a bilateral change in the retinal pigment epithelium of the macula that gives the commonly described appearance of a bull’s-eye.

Eye damage due to Plaquenil is not common,” he says. “Rarely will anybody who has good vision and minimal symptoms develop loss of central vision or ability to read if annual screening is done and visual are symptoms reported as soon as they occur so the medication can be stopped if toxicity occurs.
