Plaquenil Hydrochloroquine or Aralen Chloroquine • Annual screening after 5 years of use **Interesting, The Royal College of Ophthalmologists in Great Britain does NOT recommend routine screening for toxicity with antimalarial drug use. Multifocal ERG has a consistent topographic distribution in the normal population. However, the summed amplitude of multifocal ERG can vary significantly among normal subjects. Therefore, topographic abnormalities via a three-dimensional distribution map are useful for the interpretation of multifocal ERG in diseased patients. Multifocal ERG mfERG A mfERG can help confirm the presence of retinal toxicity when perimetry or other tests detect abnormalities11 Generates an array of local ERG responses that corresponds to the central 40 degrees mfERG is better than full field ERG at detecting local changes in the macula She was previously treated with hydroxychloroquine (Plaquenil) 200mg bid (6.5mg/kg) for 10 years, which was stopped one year prior to presentation.
