    Plaquenil and visual field testing


    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.

    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. Paracentral scotomas have been reported prior to the associated maculopathy, so an amsler grid test or central 10-2 visual field perimetry was recommended. 2,5. Additionally, color vision––helping in the assessment of macular integrity––was recommended as an optional test. 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.

    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.

    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. In early cases of toxicity, visual fields will typically reveal a paracentral scotoma. 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. Macular Society Eye screening for patients taking hydroxychloroquine. Hydroxychloroquine is a medication used to treat several conditions including rheumatoid arthritis, systemic lupus erythematosus, some skin conditions especially photosensitive ones and others that involve inflammation.

    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. 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. After two normal visual field exams, does that mean further visual field testing need be done at less frequent intervals, despite continuing plaquenil therapy?
