Hydroxychloroquine and Chloroquine Retinopathy

Multifocal electroretinography was shown to have a high sensitivity but variable specificity when verified against AVF, OCT, FAF, and a combination of tests. The greater average cumulative dose in the false-positive group compared with the true-negative group when mfERG was verified against AVF suggests that mfERG may have the ability to detect cases of toxicity earlier than other modalities. There is an unclear risk of bias in the available evidence, and future studies should adhere to Standards for Reporting of Diagnostic Accuracy reporting guidelines.
