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. Zentiva hydroxychloroquine cost Chloroquine diphosphate for ich Cr3 ii chloroquine 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. 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 the central area being depressed in the 24-2 and 30-2 testing strategies, it is difficult to discern the central 2-degree field of sparing seen in the 10-2 tests. 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. 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.

Scotoma analysis of 10-2 visual field testing with a white.. Plaquenil Toxicity Screening - Retina Group of New York. In patients of Asian descent, it is recommended that visual field testing be performed in the central 24 degrees instead of the central 10 degrees. It is recommended that hydroxychloroquine be discontinued if ocular toxicity is suspected and the patient should be closely observed given that retinal changes and visual disturbances may progress even after cessation of therapy. Central computerized visual field test SD-OCT spectral domain optical coherence tomography A Word From Verywell Research has shown that your risk of developing retinopathy is higher the longer you are taking Plaquenil. 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.
