Comparison of OCTA to conventional imaging modalities for the diagnosis of eye diseases
Retinal blood flow measurement is of scientific and clinical value. For this purpose retinal vessel morphology (such as diameter, vessel wall thickness, etc) determination is crucial. Diff...
The purpose of the present study is to determine if the retinal thickness estimates of the Stratus OCT, the 3D OCT-1000, and the CirrusHD OCT are comparable in diabetic and in healthy indi...
The investigators aim to evaluate the efficacy of the new Optical Coherence Tomography based Angiography (OCT-A) softwares in the diagnosis and management of glaucoma.
The purpose of this research is to evaluate optical coherence tomography (OCT) and FDA approved device used to image diseases of the eye. The ultra-high resolution OCT is a non-significan...
To describe the retinal vasculature and choriocapillaris, as well as the transition zone between the diseased and healthy tissue, in eyes with inherited retinal degenerations using optical coherence t...
To describe the quantitative optical coherence tomography angiography analysis of the superficial and deep retinal capillary plexus in a case of A29 birdshot chorioretinopathy (BCR) complicated by ret...
Optical coherence tomography angiography (OCT-A) allows noninvasive visualization of retinal vessels in vivo. OCT-A was used to characterize the vascular network of the mouse retina and was compared w...
To report subclinical retinal hemangioblastoma detected by enhanced depth imaging optical coherence tomography and fluorescein angiography in at-risk twins.
To evaluate the retinal perfusion in patients with chiasmal compression using optical coherence tomography angiography (OCTA).
An imaging method using LASERS that is used for mapping subsurface structure. When a reflective site in the sample is at the same optical path length (coherence) as the reference mirror, the detector observes interference fringes.
A localized defect in the visual field bordered by an area of normal vision. This occurs with a variety of EYE DISEASES (e.g., RETINAL DISEASES and GLAUCOMA); OPTIC NERVE DISEASES, and other conditions.
Visualization of a vascular system after intravenous injection of a fluorescein solution. The images may be photographed or televised. It is used especially in studying the retinal and uveal vasculature.
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)
A technique of diagnostic imaging of RETINA or CORNEA of the human eye involving the measurement and interpretation of polarizing ELECTROMAGNETIC WAVES such as radio or light waves. It is helpful in the diagnosis of GLAUCOMA; MACULAR DEGENERATION; and other retinal disorders.
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...
Ophthalmology is the branch of medicine that is devoted to the study and treatment of eye diseases. As well as mild visual defects correctable by lenses, ophthalmology is concerned with glaucoma, uveitis and other serious conditions affecting the eye, ...
