To characterize structural changes of HCQ retinopathy with SD-OCT after drug cessation. Setting: Private practice and academic institution. Patient Population: Patients at New England Eye Center and Ophthalmic Consultants of Boston in Boston, MA diagnosed with HCQ retinopathy and followed after drug cessation. Chloroquine cancer stem cell What happens if you quit taking plaquenil Hydroxychloroquine class action lawsuit A subtle case of hydroxychloroquine retinopathy spectral domain optical coherence tomography findings Skip to main content Thank you for visiting Purpose. To investigate the distribution of outer retinal changes in hydroxychloroquine HCQ retinopathy and explore optical coherence tomography OCT protocols to maximize the sensitivity of HCQ retinopathy detection in Asian patients. Objective To determine whether early toxic effects from hydroxychloroquine HCQ could be detected by spectral-domain optical coherence tomography SD-OCT before symtomatic visual loss occured. Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center.
