Influence of scanning area on choroidal vascularity index measurement using optical coherence tomography

, 2017
Recently, choroidal vascularity index (CVI) is proposed as a novel tool to evaluate the choroidal vasculature. In this study, we investigate the impact of scanning area on CVI measurement using spectral‐domain optical coherence tomography (SD‐OCT)

Macular telangiectasia type 2 genetic risk variants associated with clinical characteristics in the Slovenian cohort

Acta Ophthalmologica, EarlyView.
Abstract Purpose Early diagnosis of macular telangiectasia type 2 (MacTel) remains challenging, and the contribution of genetic variation to its clinical heterogeneity is unclear. This study investigated associations between MacTel risk variants and clinical characteristics in a Slovenian cohort.

Inter‐eye microvascular asymmetry across stages of diabetic retinopathy: An OCT angiography study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate inter‐eye asymmetry in macular microvascular parameters across different stages of diabetic retinopathy (DR) using OCT angiography, and to explore the associations with clinical factors. Methods This cross sectional study included 442 eyes of 221 patients with diabetes mellitus type 2. Central subfield thickness (CST), area

Concurrent macular neovascularization in shallow irregular retinal pigment epithelium elevation phenotypes in age‐related macular degeneration and chronic central serous chorioretinopathy: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract This systematic review and meta‐analysis synthesized the reported frequency of concurrent macular neovascularization (MNV) among selected eyes with author‐defined shallow irregular retinal pigment epithelium (RPE) elevations in age‐related macular degeneration (AMD) and chronic central serous chorioretinopathy (CSC).

Correcting Axial Length‐Related Magnification Errors in Optical Coherence Tomography Angiography Improves Machine Learning Classification Performance in High Myopia

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To determine whether axial length‐related magnification correction in optical coherence tomography angiography (OCTA) improves machine learning classification of high myopia and resolves inconsistencies in the values and discriminatory power of OCTA microvascular metrics.

Suppression of Retinal Neovascularisation by Tetrahedral Framework Nucleic Acids‐Resveratrol Via Dual Anti‐Angiogenesis and Anti‐Inflammation

Cell Proliferation, EarlyView.
Resveratrol‐loaded tetrahedral framework nucleic acids (tFNAs‐RSV) enable concurrent anti‐angiogenic and anti‐inflammatory therapy, enhancing ocular delivery and bioactivity. In hypoxia‐induced retinal neovascularisation, tFNAs‐RSV reduce neovascular lesions, vascular leakage and inflammatory infiltration by suppressing HIF‐1, p38 MAPK and NF‐κB p65 ...

Rethinking diabetic retinopathy: Homeostatic mechanisms for retinal clearance

Diabetic Medicine, EarlyView.
In the healthy retina, balanced production and clearance of metabolic waste and fluid maintain retinal homeostasis and normal visual function. Diabetes disrupts this balance, increasing the accumulation of metabolic waste products, including advanced glycation end products (AGEs) and advanced lipoxidation end products (ALEs), while impairing waste and ...

Peripapillary Choroidal Vascularity Index and Microstructure of Parapapillary Atrophy

Investigative Opthalmology & Visual Science, 2019
To investigate the association between the microstructure of β-zone parapapillary atrophy (βPPA) and choroidal vascularity index (CVI) determined by spectral-domain optical coherence tomography (SD-OCT) in glaucomatous eyes.A total of 160 eyes of 160 primary open-angle glaucoma patients with βPPA were included. Total choroidal area (TCA), luminal area (
