    Visual field loss in plaquenil retinopathy


    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.

    If advanced, hydroxychloroquine retinopathy can cause symptoms of loss of peripheral vision, and then in later stages, central vision can become affected too. If hydroxychloroquine retinopathy is advanced, it can result in permanent loss of sight in both eyes that can impact quality of life and activities such as driving and reading. It is unlikely that all the visual field will be lost, even in advanced hydroxychloroquine retinopathy. Evaluation by visual field testing and/or spectral domain optical coherence tomography OCT showed the overall prevalence of retinal thinning and photoreceptor damage or visual field loss was 7.5%. The risk climbed with greater daily dosage and duration of therapy, reaching a prevalence of nearly 20% after 20 years on hydroxychloroquine JAMA. Visual fields. In early cases of Plaquenil toxicity, an early indicator of damage is the appearance of a paracentral scotoma seen on automated visual field testing in the absence of fundus changes. 18 Each of the testing strategies can be used to detect early toxicity changes, but the presentation of the visual field effects will vary. Due to.

    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).

  3. Jan 05, 2020 Hydroxychloroquine Plaquenil and chloroquine cause ocular toxicity to various parts of the eye such as the cornea, ciliary body, and retina. Chloroquine can also induce cataract formation; however, no reports of hydroxychloroquine and cataract have been reported. This article focuses upon hydroxychloroquine retinopathy. Disease

    The main outcomes were toxicity as determined by characteristic visual field loss or retinal thinning and photoreceptor damage. They also examined risk factors and prevalence. The study findings revealed that when hydroxychloroquine was used at doses 5mg /kg, the risk of retinopathy was 1% in the first 5 yrs. 2% in 10 yrs. 20 % after 20 yrs. Advanced cases may demonstrate widespread retinal pigment epithelium atrophy, with a reduced visual field and decreased night vision. 3. Visual field. Parafoveal sensitivity loss is an early sign that may precede fundus changes. A computerized white-on-white 10-2 visual field test enables good resolution to test for macular sensitivity. 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

    I take methotrexate also but the plaquenil messed with my vision and I had to quit taking it. And I'm beginning to see more changes in my feet and hands. you never know if what you say gives that person one more step closer to her or his answer.

    Chloroquine Indications, Side Effects, Warnings - A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen.
