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 ...

Near-infrared fundus autoflorescence imaging in solar retinopathy
GMS Ophthalmology Cases, 2017 Solar retinopathy is a rare clinical entity caused by photochemical damage to the retinal pigment epithelium layer and photoreceptors of the fovea. Here we describe a case of a 33-year-old female patient diagnosed by near-infrared fundus autofluorescence

Norbixin Protects Retinal Pigmented Epithelium Cells and Photoreceptors against A2E-Mediated Phototoxicity In Vitro and In Vivo. [PDF]
PLoS ONE, 2016 The accumulation of N-retinylidene-N-retinylethanolamine (A2E, a toxic by-product of the visual pigment cycle) in the retinal pigment epithelium (RPE) is a major cause of visual impairment in the elderly.

Automated segmentation and extraction of posterior eye segment using OCT scans [PDF]
arXiv, 2021 This paper proposes an automated method for the segmentation and extraction of the posterior segment of the human eye, including the vitreous, retina, choroid, and sclera compartments, using multi-vendor optical coherence tomography (OCT) scans. The proposed method works in two phases.

OCT-GAN: Single Step Shadow and Noise Removal from Optical Coherence Tomography Images of the Human Optic Nerve Head [PDF]
arXiv, 2020 Speckle noise and retinal shadows within OCT B-scans occlude important edges, fine textures and deep tissues, preventing accurate and robust diagnosis by algorithms and clinicians. We developed a single process that successfully removed both noise and retinal shadows from unseen single-frame B-scans within 10.4ms.

Quantitative optical coherence tomography reveals rod photoreceptor degeneration in early diabetic retinopathy [PDF]
arXiv, 2021 Purpose: This study is to test the feasibility of optical coherence tomography (OCT) detection of photoreceptor abnormality and to verify the photoreceptor abnormality is rod predominated in early DR . Methods: OCT images were acquired from normal eyes, diabetic eyes with no diabetic retinopathy (NoDR) and mild DR.
