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. Plaquenil toxicity aao How is chloroquine diphosphate used in blood banking Hydroxychloroquine in canada Sep 15, 2014 Fundus autofluorescence FAF indicates marked changes of macular toxicity in the mild and severe cases, represented by the central mottled hypo autofluorescence with surrounding rim of hyper autofluorescence, due to the retinal pigment epithelium RPE loss. FAF is a sensitive indicator of the RPE degeneration caused by the toxic progression. 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. 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. 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.
