Multiple commercially available imaging systems, including the fundus camera, the confocal scanning laser ophthalmoscope, and the ultra-widefield imaging device, are available to the. To detect chloroquine toxicity, the American Academy of Ophthalmology recommends performing fundus examinations, 10-2 automated visual fields, and at least one objective test multifocal electroretinography mfERG, fundus autofluorescence imaging, or spectraldomain optical coherence tomography SD-OCT. 1 By contrast, Amsler grid testing.
