    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.

    To analyze Humphrey visual field HVF findings in hydroxychloroquine HCQ retinal toxicity. HVF tests were interpreted retrospectively in this observational case series of 15 patients with HCQ. Here, we’ll only talk about the Humphrey visual field perimeter, which is used for 99% of visual field tests. It’s an automated, static perimeter unlike Goldmann kinetic perimetry which requires a human operator, and uses a moving target. The Humphrey uses fixed points of light which are shown at different intensity levels. Hydroxychloroquine is an analogue to the much older drug chloroquine. Chloroquine was first used as an antimalaria drug. Chloroquine was first used as an antimalaria drug.

    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).

  5. Screening for hydroxychloroquine retinopathy is dependent on ancillary testing as the clinical examination is insensitive and nonspecific for retinopathy.1 Since the early 1990s, the 10–2 visual field VF has been the most commonly used ancillary test.2–4 Multifocal electroretinography mfERG, spectral domain optical coherence tomography SD-OCT, and fundus autofluorescence FAF have been introduced more recently, and gained wider acceptance when advocated in the revised guidelines.

    I was told from the start by my rheumatologist I would have to have eye exams including visual field exams every six months due to the plaquenil therapy. My first two exams did include these tests. But my next six month appointment is coming up, and they told me I didn't need the visual field test this time so the appointment would be shorter. Visual field testing actually maps the visual fields to detect any early or late signs of glaucomatous damage to the optic nerve. In order to find and follow glaucoma, visual fields are measured by a computer one eye at a time. One eye is covered and the patient places his or her chin in a type of bowl. Hydroxychloroquine retinopathy is thought to be infrequent but of increasing prevalence because patients use the drug for many years or have undue exposure from overdosage or renal failure. 1 Screening in previous decades was primarily by subjective functional measures, such as the central visual field.
