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 liver failure Stopping plaquenil medication Hydroxychloroquine retinopathy symptoms Eyewiki plaquenil Apr 10, 2019 When treating lupus or arthritis, Plaquenil is usually given daily for several weeks or months. For best results, keep using the medication as directed. Talk with your doctor if your symptoms do not improve after 6 months of treatment. While using Plaquenil, you may need frequent blood tests and vision exams. Baseline visual fields VFs and spectral-domain optical coherence tomography SD-OCT scans are useful but not essential, unless abnormalities are present at baseline. Initially, annual screening can be deferred, unless the patient is in a high-risk group. But beginning at the 5-year mark, all patients should be screened every year. The study was a Kaiser Permanente retrospective case-control study that examined 2361 patients who had used hydroxychloroquine continuously for at least 5 years according to pharmacy records and who were evaluated with visual field testing or spectral-domain optical coherence tomography. 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.

The American Academy of Ophthalmology has published several dosing and screening recommendations for hydroxychloroquine to avoid potential retinal toxicity, yet some patients still experience. Because early toxicity changes can be revealed on SD-OCT, it is prudent to perform a baseline screening of patients taking Plaquenil. Multifocal ERG has the ability to detect early macular dysfunction, so it should be included as part of baseline screening. A maximum daily dose of Plaquenil of 5.0mg/kg real weight is recommended. This is a late finding, however, and too late for screening to be useful. 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”.
