In Sjögren’s, Plaquenil is used to treat many symptoms of Sjögren’s including fatigue, joint symptoms of arthritis and arthralgias (joint pain), dry mouth and dry eyes. Similar to its use in systemic lupus erythematosus, many clinicians feel that it is useful in reducing general Sjögren’s “disease activity.” One of the reasons that physicians feel comfortable in prescribing Plaquenil is its low risk to benefit ratio. Chloroquine salt cambodia resistance Common ingredients of chloroquine Plaquenil and muscle stiffness Does plaquenil treat rhupus In obvious toxicity, the nasal inner subfield showed more thinning than the temporal inner subfield at 12 months after drug cessation p = 0.018, 95 % CI −1 to −8 μm. Conclusions Once HCQ retinopathy is diagnosed and the medication is discontinued, structural retinal changes commonly occur. The American Academy of Ophthalmology has published several dosing and screening recommendations for hydroxychloroquine to avoid potential retinal toxicity, yet some patients still experience permanent vision loss resulting from hydroxychloroquine retinopathy due to improper dosing of the drug and improper screening. C, Moderate retinal toxicity, with marked outer retinal thinning on both sides of the fovea arrowheads and a prominent ring scotoma but still no pigmentary changes visible in the fundus. D, Severe retinal toxicity, with bull’s eye maculopathy on the fundus image, disruption of the retinal pigment epithelium on spectral-domain OCT, and severe visual field defects. As with any medication, allergic reactions including skin rashes and non-allergic reactions can occur. This means that the side effects of Plaquenil are mild and infrequent compared with its potential benefits.

Nevertheless, time domain OCT machines are more widely. Time Domain OCT in Hydroxychloroquine Plaquenil Toxicity.. Toxic Retinopathy With Hydroxychloroquine Therapy. Hydroxychloroquine-related retinal toxicity Rheumatology.. Several reports previously described abnormal OCT findings, including parafoveal thinning 18,19 and abnormalities in the parafoveal photoreceptor inner segment/outer segment junction 19 in patients with chloroquine or hydroxychloroquine retinal toxicity. However, those patients with noticeable OCT changes had either clinical symptoms, visual loss, visual field defects, color vision deficiency or abnormal mfERG findings. Retinal photograph showing classic “bull’s eye” retinopathy of hydroxychloroquine toxicity, which represents atrophy of the retinal pigment epithelium. This is a relatively late change, and good screening can detect toxicity before any bull’s eye is visible. Once retinal toxicity from hydroxychloroquine occurs, it is thought that the retinal changes are permanent and the disease can progress even if hydroxychloroquine is stopped for 1 to 3 years. Newer techniques for evaluation of retinal disease have been developed and these techniques can detect retinal toxicity earlier.
