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. Plaquenil side effects bone pain Plaquenill oct macula How long does it take for plaquenil to take effect 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. 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 American Academy of Ophthalmology has published guidelines for monitoring patients for Plaquenil toxicity. Some cases are difficult to detect, especially if other eye problems are present. Current testing for Plaquenil toxicity may include Visual field testing to evaluate for missing spots near the center of the vision. 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. Plaquenil visual field testing How to Succeed in Plaquenil Screenings, MEDICAL POLICY Visual Field Examination Plaquenil inflammatory arthritis Hydroxychloroquine is a well tolerated medication for various rheumatologic and dermatologic conditions. Its main side effects are gastrointestinal upset, skin rash, headache, and ocular toxicity. Within the eye, hydroxychloroquine negatively impacts the cornea, ciliary body, and retina.

Methods of visual field testing Confrontation Visual Fields Estimates the patient’s visual field limits as compared to the clinician’s field Helpful in picking up gross defects such as hemianopsia, quadrantanopsia, or altitudinal loss Typically part of the basic patient workup 17 Amsler Grid Used by the patient to self-monitor changes in the central 10° of the visual field A baseline ocular examination is recommended within the first year of starting Plaquenil. The baseline exam should include best corrected distance visual acuity BCVA, an automated threshold visual field VF of the central 10 degrees with retesting if an abnormality is noted, and spectral domain ocular coherence tomography SD-OCT. Plaquenil hydroxychloroquine Disease Interactions. There are 8 disease interactions with Plaquenil hydroxychloroquine The use of 4-aminoquinolines is generally considered contraindicated in the presence of retinal or visual field changes, whether attributable to 4-aminoquinoline compounds or to any other etiology.
