Fundus Autofluorescence and mfERG for Early Detection of Retinal Alterations in Patients Using Chloroquine/Hydroxychloroquine

Abstract

FAF imaging can be reliably used to detect early retinal pigment epithelial alterations in CQ/HCQ retinopathy. Ophthalmoscopy and fluorescein angiography appear to be less sensitive. With the mfERG, more retinal abnormalities were detected compared with FAF imaging.
