#1
Mohab Eldeeb, Errol W Chan, Amer Omar
SIGNIFICANCE: Hydroxychloroquine retinopathy causes irreversible central visual loss and can progress despite medication discontinuation. Appropriate dosing and recognition of early disease are important to minimize adverse visual sequelae. In 2016, the American Academy of Ophthalmology updated its 2011 recommendations for dosing, screening, and monitoring of hydroxychloroquine retinopathy. PURPOSE: The aim of this study was to report a case of hydroxychloroquine retinopathy in a patient who developed toxicity on a dose meeting safety thresholds from the 2011 guidelines (i...

PURPOSE: The aim of this work is the determination of quantitative diagnostic criteria based on the spectral characteristics of fundus autofluorescence to detect early stages of degeneration in the retina and retinal pigment epithelium (RPE). METHODS: RPE cell suspension samples were obtained from the cadaver eyes with and without signs of age-related macular degeneration (AMD). Fluorescence analysis at an excitation wavelength of 488 nm was performed. The fluorescence lifetimes of lipofuscin-granule fluorophores were measured by counting time-correlated photon method...

Purpose: The aim of this study was to determine whether somatotype influences the risk of hydroxychloroquine (HC) retinopathy (HCR) and whether dosing by real body weight (RBW), ideal body weight (IBW), or the lesser of these better predicts the risk of HCR. Patients and methods: A total of 565 patients taking HC for whom height and weight were recorded and a sensitive ancillary testing modality was used including 10-2 visual fields, spectral domain optical coherence tomography, fundus autofluorescence imaging, and multifocal electroretinography were enrolled...

Bisretinoid fluorophores form in photoreceptor outer segments from nonenzymatic reactions of vitamin A aldehyde. The short-wavelength autofluorescence (SW-AF) of fundus flecks in recessive Stargardt disease (STGD1) suggests a connection to these fluorophores. Through multimodal imaging, we sought to elucidate this link. Flecks observed in SW-AF images often colocalized with foci exhibiting reduced or absent near-infrared autofluorescence signal, the source of which is melanin in retinal pigment epithelial (RPE) cells...
