    Unless 20% or more of the retina is affected by a diseased state, the ERGs are usually normal. In other words, a legally blind person with macular degeneration, enlarged blind spot, or significant central scotomas will have a normal full-field ERG.

    The most prevalent pattern was pericentral loss type P; 23 eyes 62%, followed by full-field loss type F; eight eyes 22%, and central loss type C; two eyes 5%. A fourth pattern of loss also was seen, characterized by loss only in the periphery type O; four eyes 11%. The full-field ERG Ganzfeld; ffERG measures the stimulation of the entire retina with a flashlight source under dark-adapted scotopic and light-adapted photopic types of retinal is useful in detecting disease with widespread generalized retinal dysfunction i.e. cancer associated retinopathy, toxic retinopathies, and cone. Aug 30, 2011 The overall prevalence of toxicity in this group was 7.5% with a wide variation in daily dose and duration of use. Beyond this point the risk increases sharply to 20% after 20 years 7. The risk is lower with a lower dose however there is no true safe dosage for longer duration of use.

    Erich Sutter adapted the mathematical sequences called binary -sequences, creating a program that can extract hundreds of focal ERGs from a single electrical signal. An important development in ERGs is the multifocal ERG (mf ERG).

    Aug 06, 2014 Conversely, multifocal ERG, with its ability to record localized central retinal defects, has gained acceptance as an excellent candidate for detecting subtle changes in the early stages of toxicity. 20 Raj Maturi, MD, and colleagues first reported a marked reduction in the central 16˚ mfERG amplitude in a patient with manifest HCQ retinopathy in the setting of a normal full-field ERG. 21 Similar results have been obtained by subsequent studies characterizing HCQ users. Mf-ERG amplitude reduction is most common in ring 2, followed by ring 3, 4 and 1. Delayed implicit times are less common. Electroretinography ERG In 2015, Tzekov and Madow 8 stated that birdshot chorioretinopathy BSCR is a rare form of autoimmune posterior uveitis that can affect the visual function and, if left untreated, can lead to sight-threatening complications and loss of central vision.

    Hydroxychloroquine - Wikipedia Hydroxychloroquine HCQ, sold under the brand name Plaquenil among others, is a medication used for the prevention and treatment of certain types of malaria. Specifically it is used for chloroquine-sensitive malaria. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. It is taken by mouth.
