Although FAF technology has been referenced in medical research for more than 40 years, advances over the last decade have made it increasingly relevant as an ophthalmic imaging technique suitable for daily practice. FAF provides a view of the disease processes from a metabolic perspective. Severe itching plaquenil Hydroxychloroquine and folic acid Early Macular Degeneration In its early stages, dry age-related macular degeneration AMD may show a wide variety of FAF patterns that are not always visible funduscopically. These patterns were categorized into eight phenotypes and described by the Fundus Autofluorescence in Age-related Macular Degeneration FAM study group. 3 Fundus Autofluorescence Is Not the Best Early Screen for Hydroxychloroquine Toxicity—Reply Ian R. Gorovoy, MD; Mark S. Gorovoy, MD Fundus autofluorescence images of the left eye of a 59-year-old women with sarcoidosis who received 200 mg of hydroxychloroquine sulfate twice daily for 15 years. Hydroxychloroquine Maculopathy An Update on Screening and Diagnosis A brief guide for imaging SHIRI SHULMAN, MD. H ydroxychloroquine HCQ; Plaquenil, Sanofi, Bridgewater, NJ is an antimalarial agent that is also commonly used as a treatment for a variety of rheumatologic and dermatologic conditions, such as rheumatoid arthritis and systemic lupus erythematosus. It has also helped us understand certain pathophysiological mechanisms. Research has shown it to be effective in the early detection of retinal disease and the potential predictive makers for progression. Images early plaquenil toxicity fundus autoflurouecense How to Succeed in Plaquenil Screenings, Fundus Autofluorescence in Hydroxychloroquine Toxicity.

Update on Plaquenil Testing. Retinal Physician - Hydroxychloroquine Maculopathy An Update.. Expanded spectral domain-OCT findings in the early detection.. Participants. Twenty-four eyes of 12 patients with definite HCQ toxicity, 31 eyes of 16 clinically normal patients at high risk of developing HCQ toxicity taking HCQ longer than 5 years, and 16 eyes of 8 clinically normal patients at low risk of developing HCQ toxicity taking HCQ fewer than 5 years, as well as 22 age-matched healthy subjects. Figure 1 is an image of an ocular fundus using autofluorescence to designate an area of retinal damage. To detect chloroquine toxicity. Plaquenil toxicity first affects small areas of the retina between 5° and 15° from the fovea. Figures 2 and 3 show three patients at different stages of toxicity. Advanced hydroxychloroquine toxicity presents as a bullseye maculopathy. Since retinal toxicity is usually irreversible, early detection of retinal toxicity and cessation of the offending agent is the best treatment. Corneal toxicity presents as an intraepithelial deposition of the drug into the cornea, which rarely affects vision.
