The purpose of the study is to investigate novel electroretinography (ERG) devices in the detection of hydroxychloroquine retinopathy. Two devices (the RETEval full-field and flicker ERG and UTAS multifocal ERG) will be evaluated in this study, comparing device outputs to standard of care screening tests, in groups of participants characterised by presence or absence of hydroxychloroquine-related retinopathy.

The sensitivity and specificity of both devices to discriminate between NO, POSSIBLE and DEFINITE hydroxychloroquine retinopathy compared to standard screening tests
Timeframe: All tests required to determine sensitivity and specificity of both devices compared to standard retinal imaging will be completed in a single visit. Safety will be evaluated up to 1 week post-visit.
