This study reports on abnormalities on optical coherence tomography OCT due to hydroxychloroquine HCQ toxicity using data from 10 patients with chronic retinopathy but normal Humphrey visual field testing. The OCT alterations included attenuation of the parafoveal ellipsoid zone and loss of a clear continuous interdigitation zone.

Early Hydroxychloroquine OCT Abnormalities Preceding.. My Take on New Ocular Screening Guidelines for Plaquenil.. Unfortunately, clinically evident early structural changes can be subtle and usually preceded by abnormalities in functional tests such as visual field examination, multifocal electroretinography mfERG, fundus autofluorescence FA imaging, and optical coherence tomography. Recent findings suggest that Plaquenil toxicity can develop among. C4 is a protein that play an important role in immune system functioning, and low blood values may indicate more severe flares compared to those who remained on Plaquenil. This is the largest study comparing outcomes in people who remain on Plaquenil compared with those who discontinue the drug, and the findings support those of previous studies. It causes degenerative changes, definition OCT revealing disruption and loss of the external limiting membrane as early OCT findings.
