To evaluate the optical coherence tomography angiography (OCTA) features of patients with Behçet disease (BD) without ocular involvement.
This article was published in the following journal.
Name: Ophthalmic surgery, lasers & imaging retina
Optical coherence tomography angiography (OCTA) is a novel imaging modality, and its role in the clinical evaluation of patients remains to be defined. In this report, the authors describe a case of a...
Multiple image averaging (MIA) is a new approach to improve OCT angiography (OCTA) imaging. The aim of this work was to analyze the impact of MIA on image quality and quantitative OCTA parameters.
To measure the vascular density (VD) of the retinal capillary plexuses by optical coherence tomography angiography (OCTA) after surgery for an idiopathic macular hole.
Ocular and brain microcirculation share embryological and histological similarities. The retinal vascular fractal dimension (FD) is a marker of retinal vascular complexity of the vascular tree. The pu...
To assess the effect of pan-retinal photocoagulation (PRP) on choroidal vascular parameters in eyes with advanced diabetic retinopathy (DR).
Repeatability and Reproducibility of OCTA Image Quality with the Heidelberg Engineering SPECTRALIS
This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography angiography (OCTA) to assess the structure and function of the retinal microvasculature i...
All participants will underwent imaging using the OCTA system (Zeiss) with the anterior segment optical adaptor lens. The main outcomes are iris blood flow density and vascular density.
The cardiovascular parameters of prolonged physical exercice have been studied, but very little data is available about the retinal vascularization. The eye allows in vivo visualization o...
Diabetic retinopathy (DR) is a leading cause of vision loss in working-age Americans. Capillary damage from hyperglycemia causes vision loss through downstream effects, such as retinal isc...
A group of rare, idiopathic, congenital retinal vascular anomalies affecting the retinal capillaries. It is characterized by dilation and tortuosity of retinal vessels and formation of multiple aneurysms, with different degrees of leakage and exudates emanating from the blood vessels.
A method of differentiating individuals based on the analysis of qualitative or quantitative biological traits or patterns. This process which has applications in forensics and identity theft prevention includes DNA profiles or DNA fingerprints, hand fingerprints, automated facial recognition, iris scan, hand geometry, retinal scan, vascular patterns, automated voice pattern recognition, and ultrasound of fingers.
A membrane on the vitreal surface of the retina resulting from the proliferation of one or more of three retinal elements: (1) fibrous astrocytes; (2) fibrocytes; and (3) retinal pigment epithelial cells. Localized epiretinal membranes may occur at the posterior pole of the eye without clinical signs or may cause marked loss of vision as a result of covering, distorting, or detaching the fovea centralis. Epiretinal membranes may cause vascular leakage and secondary retinal edema. In younger individuals some membranes appear to be developmental in origin and occur in otherwise normal eyes. The majority occur in association with retinal holes, ocular concussions, retinal inflammation, or after ocular surgery. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p291)
Blockage of the RETINAL VEIN. Those at high risk for this condition include patients with HYPERTENSION; DIABETES MELLITUS; ATHEROSCLEROSIS; and other CARDIOVASCULAR DISEASES.
Locations, on the GENOME, of GENES or other genetic elements that encode or control the expression of a quantitative trait (QUANTITATIVE TRAIT, HERITABLE).
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
