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. Plaquenil for ovarian cancer Hydroxychloroquine sulphate bp 200mg These findings prompted the question of possible early hydroxychloroquine retinopathy. Fluorescein angiogram of left macula in patient with hydroxychloroquine retinopathy. Reprinted from American Journal of Ophthalmology, Vol 104, Johnson and Vine, Hydroxychloroquine therapy in massive total doses without retinal toxicity, pages 139-144. Researchers recently reported on early optical coherence tomography OCT abnormalities due to HCQ toxicity that may develop through normal visual field VF testing. They found that patients with high-risk HCQ exposure and normal VF testing may develop subtle but characteristic OCT abnormalities. In early toxicity there are no visible signs, but field, OCT and mfERG changes can be detected. If abnormalities are present only unilaterally, investigate other causes besides hydroxychloroquine toxicity see “Differential Diagnosis of Bull’s-Eye Maculopathy”. 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. Oct findings in plaquenil toxicity How to Succeed in Plaquenil Screenings, Spotting the Telltale Signs of Plaquenil Toxicity Cheap aralen phosphate Conclusions SD-OCT and AO detected abnormalities that correlate topographically with visual field loss from hydroxychloroquine toxicity as demonstrated by HVF 10-2 and may be useful in the detection of subclinical abnormalities that precede symptoms or objective visual field loss. Spectral-Domain Optical Coherence Tomography and Adaptive.. Hydroxychloroquine-Induced Retinal Toxicity - American.. In Hydroxychloroquine Toxicity. Characteristic signs of retinal toxicity related to the use of chloroquine or hydroxychloroquine include paracentral or pericentral scotomas and a bull's eye maculopathy, shown as bilateral pigmentary changes of the macula with relative sparing of the central fovea. The mechanism to explain these clinical signs remains unclear. Dence of hydroxychloroquine maculopathy. Table. Clinical, High-Speed Ultra–High-Resolution Optical Coherence Tomography, and Multifocal Electroretinogram Findings From Patients Receiving Hydroxychloroquine Patient No./ Age, y Hydroxychloroquine Dosage, mg/d Diagnosis Treatment, y Symptoms Visual Acuity, OD, OS Color Vision Visual Fields mfERG. The optical coherence tomography angiography findings showed that the parafoveal deep temporal and deep hemi-inferior vascular plexus density was reduced in patients taking hydroxychloroquine for more than 5 years despite having normal perimetry.
