Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight. Chloroquine flatworms Plaquenil for lupus rash The other major concern with maculopathy is that it may cause test abnormalities that interfere with the interpretation of screening procedures visual fields, SD OCT, fundus autofluorescence FAF, multifocal electroretinogram mfERG. Thus, significant central photoreceptor loss would be a contraindication. Visual field testing is non-covered as a screening test. CPT requires an interpretation of the results of this test. Usually this is a short narrative describing the reliability of the results, the findings, any changes since the last field if available, and the clinician's impression and assessment. Visual field tests in addition to optic nerve imaging are also used to monitor glaucoma, and it will also decrease your visual field, as plaquenil can. I'm no longer taking the plaquenil, but opthamologist is insistent on following me for possible glaucoma. Hence, I still get a visual field test and optic nerve imaging study done every year. Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

If a 24-2 or 30-2 field is performed, be way of overlooking the 2-degree field of sparing seen on 10-2 fields; in these tests, a small central defect may be seen instead. Hydroxychloroquine toxicity - EyeWiki. Plaquenil and failed vision test?. Visual Field Test Learn How the Procedure Is Performed. Aug 30, 2011 Humphrey Visual Field 10-2 is sensitive at detecting subtle paracentral visual field defects and is recommended during all screening visits. SITA testing with pattern deviation plots is recommended. Wider test patterns 24-2 or 30-2 are needed for Asian patients due to the possibility of extra-macular manifestations of toxicity. Abnormal test is the visual field test, you may be asked to repeat it to make sure of the results. You will be told if any other tests are necessary and when you should be screened again. In cases of possible retinopathy, you will be recommended to continue taking 8 9 Macular Society Eye screening for patients taking hydroxychloroquine Scotoma analysis of 10-2 visual field testing with a white target in screening for hydroxychloroquine retinopathy David J Browning, Chong Lee Department of Ophthalmology, Charlotte Eye, Ear, Nose and Throat Associates, Charlotte, NC, USA Objective To quantify the variability of scotomas detected by 10-2 visual field VF testing in patients taking hydroxychloroquine without and with retinopathy. Design Retrospective review of clinical charts and visual fields. Subjects Twenty-one patients.
