Transscleral Optical Phase Imaging of the Human Retina - TOPI [PDF]

, 2019
The in vivo observation of the human retina at the cellular level is crucial to detect lesions before irreversible visual loss occurs, to follow the time course of retinal diseases and to evaluate and monitor the early effects of treatments. Despite the phenomenal advances in optical coherence tomography (OCT) and adaptive optics systems, in vivo ...

Regeneration of the zebrafish retinal pigment epithelium after widespread genetic ablation

bioRxiv, 2018
The retinal pigment epithelium (RPE) is a specialized monolayer of pigmented cells within the eye that is critical for maintaining visual system function.

Identification of Pigment Epithelium-Derived Factor in the Interphotoreceptor Matrix of Bovine Eyes

Protein Expression and Purification, 1995
Pigment epithelium-derived factor (PEDF) is a neurotrophic protein and a member of the serine protease inhibitor superfamily. Here we describe the identification of PEDF in bovine eyes and optimization of its purification from this natural source.

Histologic Basis of Variations in Retinal Pigment Epithelium Autofluorescence in Eyes with Geographic Atrophy [PDF]

Ophthalmology, 2013
Lipofuscin contained in the retinal pigment epithelium (RPE) is the main source of fundus autofluorescence (FAF), the target of an imaging method useful for estimating the progression of geographic atrophy (GA) in clinical trials. To establish a cellular basis for hyperfluorescent GA border zones, histologic autofluorescence (HAF) was measured at ...

Multifunctional Biomimetic Nanotherapeutics for Anti‐Oxidative and Anti‐Inflammatory Synergistic Therapy of Corneal Neovascularization

Aggregate, EarlyView.
An anti‐inflammatory and antioxidant metal‐organic framework (MOF) nanoplatform was prepared via one‐pot self‐assembly. In vitro and in vivo studies demonstrated that the prepared MVPC nanoparticles can effectively scavenge overproduced reactive oxygen species at diseased sites, enhance IL‐10 secretion, and suppress VEGFA expression, offering a novel ...

Multi‐Disease Detection in Retinal Imaging Using VNet with Image Processing Methods for Data Generation

Advanced Intelligent Systems, EarlyView.
This study introduces a data augmentation method that expands an ophthalmology dataset by 12x, enhancing robustness and reducing overfitting. A novel VNet architecture improves accuracy by 10% over the original dataset and 5% over Grand Challenge benchmarks.
