: 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.Design
: Diagnostic validity assessment METHODS: Setting: Institutional Patient Population: Forty-eight eyes (24 patients) with HCQ retinopathy underwent 6-mm horizontal and vertical line scans and 6 × 6-mm(2) volume scans using spectral-domain OCT (SD-OCT), and 9-mm line scans and 6 × 6-mm(2) and 12 × 9-mm(2) volume scans using swept-source OCT (SS-OCT).Observation Procedures
: Distances from the fovea to the defective photoreceptors were measured in the temporal, nasal, superior, and inferior directions from line scan OCT images. Read More
