Retinal thinning in plaquenil toxicity oct Manufacture discount plaquenil discount card It has become fairly common practice for most rheumatologists to recommend that patients being treated with hydroxychloroquine be seen for formal visual field evaluation once or twice a year to monitor for retinal toxicity. The previous AAO guideline recommended screening every 12 months. Nov 01, 2015 The incidence of retinal toxicity is associated with the cumulative dose of the drug, increasing significantly beyond 1,000 g of HCQ. This cumulative dose is created when the common dose of 400 mg/day is used for 6.8 years. Hydroxychloroquine is metabolized and secreted by both the liver and the kidneys. Ophthalmologists currently screen for hydroxychloroquine retinopathy correctly, however, their lack of familiarity with evidence-based guidelines may result in excessive follow up. Increasing awareness and implementation of the PPP could potentially reduce hydroxychloroquine retinopathy screening costs significantly.
