In practical terms, SD-OCT is most widely available, and is very sensitive, so practitioners should look for subtle parafoveal abnormalities. HCQ screening for identification of early toxicity is critical to allow for cessation of the drug and potential prevention of vision loss.17 The American Academy of Ophthalmology preferred practice patterns recommend screening initially for HCQ toxicity with a complete ophthalmic exam and either HVF 10-2 perimetry or Amsler grid testing, with other testing optional and at the discretion of the provider.4,18 While HVF perimetry and Amsler grid testing may show abnormalities even before the.
