MfERG may be the most sensitive test for early HCQ retinopathy, and numerous studies have evaluated the use of mfERG in the screening of HCQ retinopathy.19,20 Unlike full-field ERG, mfERG can localize deficiencies to the central macula, thereby detecting the subtle changes characteristic of early HCQ retinopathy.21,22 Specifically, paracentral reductions in amplitude, indicative of depressed retinal function, are the most specific waveform pattern for HCQ retinopathy Fig. 7.
