Clock-hour topography and extent of outer retinal damage in hydroxychloroquine retinopathy.

ABSTRACT: In this study, we investigated the clock-hour topographic characteristics and extent of photoreceptor and retinal pigment epithelium (RPE) damage and correlated the extent with functional defects in eyes with hydroxychloroquine retinopathy. A total of 146 eyes of 75 patients diagnosed with hydroxychloroquine retinopathy were included. The clock-hour topographic characteristics (relative to the fovea) and extent of the photoreceptor and RPE defects in the parafoveal and pericentral areas were evaluated by reviewing the radial-scan optical coherence tomography (OCT) and wide-field fundus autofluorescence (FAF) images. The extent of outer retinal damage in the parafoveal and pericentral areas were correlated with the perimetric parameters of the Humphrey 10-2 and 30-2 tests, respectively. Alt
