    Oct testing for plaquenil


    To characterize structural changes of HCQ retinopathy with SD-OCT after drug cessation. Setting: Private practice and academic institution. Patient Population: Patients at New England Eye Center and Ophthalmic Consultants of Boston in Boston, MA diagnosed with HCQ retinopathy and followed after drug cessation.

    Apr 30, 2013 SD-OCT scan from a 44-year-old woman with bilateral plaquenil toxicity. There is damage visible in the outer retina in a perifoveal distribution. Oct 21, 2010 Duration of treatment with HCQ in these patients ranged from less than one year to 22 years, daily doses from 3.0 to 7.2 mg/kg, and cumulative doses from 146 to 2628 g. Of these patients with no SD OCT abnormalities, three complained of vision changes and eight had abnormalities on HVF 10-2 perimetry. After five years of treatment, perform annual screenings, including an ocular examination, 10-2 threshold field testing, and one of the objective tests. In practical terms, SD-OCT is most widely available, and is very sensitive, so practitioners should look for subtle parafoveal abnormalities.

    Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center.

    Hydroxychloroquine HCQ has been used for therapy of rheumatologic disorders since the 1950s. Ocular toxicity associated with HCQ use was initially described in the 1960s 1, 2. The incidence of HCQ retinopathy is estimated at 1 % after consumption of HCQ for 5 years 3. Our patient demonstrates the importance of using the new recommended screening tools for the detection of early hydroxychloroquine toxicity. 10-2 HVF, SD-OCT, autofluorescence, or mfERG might have detected the hydroxychloroquine retinal toxicity on the day of her presenting symptoms and possibly earlier, potentially limiting the amount of.

    Optometric Management - Retina Sep 01, 2018 Over time, or with continued IV drug abuse, these deposits can lead to complications, such as retinal artery occlusion, neovascularization and vitreous hemorrhage, all of which can cause severe progressive vision loss. On SD-OCT, the crystalline deposits are observed as hyperreflective dots in the inner retina that distribute along the arteries.

    Hydroxychloroquine Uses, Dosage & Side Effects - Hydroxychloroquine is also an antirheumatic medicine and is used to treat symptoms of rheumatoid arthritis and discoid or systemic lupus erythematosus. Important information. Taking hydroxychloroquine long-term or at high doses may cause irreversible damage to the retina of your eye.
