Correlations between subfoveal choroidal thickness, macular thickness, and visual outcome in neovascular age-related macular degeneration using swept source OCT: insights from intravitreal aflibercept treatment

open access: yesInternational Journal of Retina and Vitreous, 2023
Background Age-related macular degeneration (AMD) is a leading cause of visual impairment among individuals aged 50 and above, often resulting in irreversible vision loss (1).

Volumetric microvascular imaging of human retina using optical coherence tomography with a novel motion contrast technique [PDF]

open access: yes, 2009
Phase variance-based motion contrast imaging is demonstrated using a spectral domain optical coherence tomography system for the in vivo human retina. This contrast technique spatially identifies locations of motion within the retina primarily associated

Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy

Shaping Function: Polymeric 3D Systems With Unconventional Geometries for Biomedical Applications

open access: yesSmall, EarlyView.
Particle shape is a key design parameter governing biological interactions. Advances in fabrication enable precise control over anisotropy and compartmentalization, allowing modulation of cellular uptake, transport, and biodistribution, ultimately enhancing therapeutic performance. ABSTRACT Polymer geometry is a primary determinant of physical behavior

Multidimensional en-face OCT imaging of the retina. [PDF]

open access: yes, 2009
Fast T-scanning (transverse scanning, en-face) was used to build B-scan or C-scan optical coherence tomography (OCT) images of the retina. Several unique signature patterns of en-face (coronal) are reviewed in conjunction with associated confocal images ...

Retinal imaging in gestational diabetes mellitus: systematic review

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objective To examine the differences in retinal structure and vasculature between women with gestational diabetes mellitus (GDM) and normoglycemic pregnant controls. Methods This was a systematic review of the available literature on retinal assessment in pregnancies with GDM compared with non‐GDM controls, conducted in PubMed, EMBASE via Ovid,

Prognostic factors of optical coherence tomography angiography in intermediate and advanced primary open‐angle glaucoma: A systematic review and meta‐analysis

open access: yesActa Ophthalmologica, EarlyView.
Abstract Conventional optical coherence tomography (OCT) has a floor effect in patients with severe visual field loss, such as seen in advanced primary open‐angle glaucoma (POAG). OCT angiography (OCTA) does not suffer from such a floor effect. However, which OCTA parameters are most useful for monitoring longitudinal progression is unclear.

Diabetic Choroidopathy: a Review of the Current Literature [PDF]

open access: yes, 2016
Diabetic retinopathy is an increasingly prevalent disease, and a leading contributor to the burden of all-cause blindness worldwide. In addition to retinal changes, choroidal abnormalities are common in patients with diabetes.

Changes in choroidal and retinal thickness 6 months before and during 18 months of orthokeratology lens treatment in myopic children

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To investigate changes in choroidal and retinal thickness before and during myopia control treatment with orthokeratology lenses (OKL) in myopic children. Methods This was a sub‐study of CONTROL and CONTROL2 studies. The present study was a 2‐year, prospective, single‐group interventional study consisting of a 6‐month pre‐treatment ...
