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. 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.

Intended audience Ophthalmologists, dermatologists, rheumatologists. Publication history information Published October 2009, replaces previous guidance of 19. Screening guidelines were updated this year, with some pertinent changes for our profession to note. Cumulative dose is no longer a risk factor, but more of a tool in the screening of our patients. Chloroquine and hydroxychloroquine 4-aminoquinolones are used by dermatologists for the treatment of a wide range of disorders. It is widely recognized that their use may lead to ocular complications, but policies for ophthalmological screening and follow-up vary widely. Initially, central visual acuity may be unaffected, but the patient may notice related paracentral scotomas that often interfere with reading. The associated classic retinal toxicity is described as a bull’s eye maculopathy (ring of depigmented retinal pigment epithelium that spares the foveal area).

The Royal College of Ophthalmologists recommendations on.. It is thought that although the bull’s eye seen on ophthalmic exam represents a disruption of the pigmented part of the retina, it is the photoreceptors that are the targets of hydroxychloroquine toxicity. Notably the new recommendations were based on a single study published in 2014 that evaluated the prevalence of and risk factors for hydroxychloroquine retinal toxicity. Screening recommendation. Guidelines and recommendations for screening for retinal toxicity have evolved over the years. In 2002 the American Academy of Ophthalmology AAO first proposed screening recommendations for HCQ associated retinal toxicity, with the salient points being 14 1.
