Hyperreflective Foci, Optical Coherence Tomography Progression Indicators in Age-Related Macular Degeneration, Include Transdifferentiated Retinal Pigment Epithelium.
Dongfeng Cao,Belinda C S Leong,Jeffrey D. Messinger,Deepayan Kar,Thomas Ach,Lawrence A. Yannuzzi,K. Bailey Freund,K. Bailey Freund,Christine A. Curcio +8 more
TL;DR: In this paper, the hyperreflective foci (HRF) indicate progression risk for advanced age-related macular degeneration (AMD) and are in part attributable to ectopic retinal pigment epithelium (RPE).

Quantitative Fundus Autofluorescence in the Developing and Maturing Healthy Eye.
Carla Pröbster,Ioana-Sandra Tarau,Andreas Berlin,Nikolai Kleefeldt,Jost Hillenkamp,Martin M. Nentwich,Kenneth R. Sloan,Thomas Ach +7 more
TL;DR: In this article, the authors report QAF in a large cohort of healthy children, including 70 healthy Caucasian children (5-18 years) were multimodal imaged, including QAF and spectral domain optical coherence tomography, and retinal thicknesses were measured at predefined locations along horizontal meridian.
Characteristics of normal human retinal pigment epithelium cells with extremes of autofluorescence or intracellular granule count
Katharina Bermond,Andreas Berlin,Ioana-Sandra Tarau,Christina Wobbe,Rainer Heintzmann,Christine A. Curcio,Kenneth R. Sloan,Thomas Ach +7 more
TL;DR: In normal eyes, outliers regarding autofluorescent granule load and AF intensity signals are rare among RPE cells, suggesting that granule deposition and subsequent AF follows intrinsic control mechanisms at a cellular level.
Hyperspectral autofluorescence characterization of drusen and sub-RPE deposits in age-related macular degeneration
TL;DR: In this article, the authors optimize histologic hyperspectral autofluorescence imaging and image analysis for recognition of drusen and sub-RPE deposits (including BLinD and basal laminar deposit), for potential clinical application.

Impact of ultraviolet radiation on the retina
TL;DR: In this paper, natural mechanisms that protect the human retina from damaging ultraviolet (UV) radiation have been investigated, such as the natural lens, modern intraocular lenses, and wearing of sunglasses with appropriate filter function, particularly in childhood and adolescence.
