Additionally, another exception occurred while executing the custom error page for the first exception. Background: The American Academy of Ophthalmology recommendations on screening for chloroquine (CQ) and hydroxychloroquine (HCQ) retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. Chloroquine intercalation Dosing plaquenil calculator World war 2 and lupus and hydroxychloroquine plaquenil Stopping plaquenil for surgery We also request a detailed baseline eye exam which includes color vision and visual field-testing, and repeated every 6-12 months to detect the earliest changes in the retina which may be reversible by stopping or reducing the dose of Plaquenil. Although we screen for them, Plaquenil rarely has any effect on blood counts, kidney or liver function. Aug 29, 2014 As a precaution, patients treated with Plaquenil are advised to get a baseline eye exam prior to starting the drug and then annually thereafter. This information provided by Neil I. Stahl, MD & Tongalp H. Tezel, MD was first printed in the The Moisture Seeker, SSF's patient newsletter for members. A 26-year-old black female presented in office for her annual comprehensive eye exam. Her medical history was significant for Plaquenil therapy spanning 12 years with a daily dose of 200mg twice daily. She presented with a best-corrected visual acuity of 20/20 OD and 20/20 OS. All preliminary testing revealed normal findings. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight. Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Baseline eye exam plaquenil Eye exam / Plaquenil -, The Risk of Retinal Toxicity with Plaquenil Hydroxychloroquine common thanRash with plaquenil Baseline Examination All patients should have a baseline ophthalmologic examination within the first year of initiating HCQ or CQ therapy with thorough risk factor assessment and fundus examination of the macula to rule out underlying disease. Baseline visual field and SD OCT are recommended if abnormalities are present e.g. macular lesions. Hydroxychloroquine Plaquenil Toxicity and Recommendations for Screening. How to Succeed in Plaquenil Screenings. Recommendations on Screening for Chloroquine and.. It is a good supplemental item, just like macular photography and color vision testing. But at the baseline exam and beginning at 5 years and thereafter of the patient taking the medication at least one of the required sstandard testing items has to be performed every year to meet these new guidelines. A 57-year-old female presented to the Ophthalmology clinic at UIHC complaining bilateral central photopsias for the past two years. She suffered from Sjogren syndrome and inflammatory arthritis and was currently treated with prednisone and methotrexate. She was previously treated with hydroxychloroquine Plaquenil 200mg bid 6.5mg/kg for 10 years, which was stopped one year prior to. Hydroxychloroquine, on the other hand, is much less toxic to the retina and there have been fewer reported eye problems. In general, a baseline ophthalmic examination should be performed upon initiation of therapy. In addition, a central visual field test and color photographs of the retina are usually taken at that time.
