    Optical coherence tomography Optical Coherence Tomography (OCT): Optical coherence tomography provides high-resolution imaging of the vitreoretinal interface, neurosensory retina, and subretinal space. Optical coherence tomography can be used to quantify retinal thickness, monitor macular edema, identify vitreomacular traction, and detect other forms of macular disease in patients with diabetic macular edema. 105,106 OCT helps in early diagnosis of macular oedema as it is more sensitive than clinically

    Introduction to Optical Coherence Tomography Optical Coherence Tomography (OCT) is a method of imaging which uses near-infrared or optical light scattering to produce three dimensional images of a medium. Medical applications are of particular interest, since OCT allows retinal and other tissues to be imaged with high resolution. I. Introduction Optical Coherence Tomography (OCT) is a method of imaging which uses near-infrared or optical light scattering to produce three-dimensional images

    last thing any of us needs is a piece of equipment sitting idle in the corner collecting dust, and along with it our simmering anger at the fact we're paying through the nose for that white elephant.           It has been 20 years since Optical Coherence Tomography (OCT) was first introduced for the diagnosis and treatment of eye disease. I became infatuated with OCT while serving as a center director at a co-management

    The most prominent medical problem that Intravascular Optical Coherence Tomography addresses, is the rupture or erosion of a coronary atherosclerosis plaque (Bouma, Villiger, Otsuka, & Oh, 2017). Plaque rupture or erosion can lead to blood clot formation, limiting blood flow to the heart, known as Acute Coronary Syndrome (ACS). Atherosclerosis is a disease where plaque is built up inside the arteries – most commonly known atherosclerosis diseases are Coronary Heart Disease (CHD), where one experiences

    In Ophthalmology, Optical coherence tomography (OCT) is a non-invasive imaging modality. It provides a cross-sectional view (tomography) of the retina tissue structures and is used widely to identify and monitor various eye diseases [1]. However, OCT images are inevitably affected by noise due to the interferometry nature of OCT imaging. Also, to avoid motion artifacts due to the fixation eye movements, the OCT clinical images are often captured at lower than nominal sampling rates [1], [2]. Therefore

    The journal article “Evaluation of Retinal Vessel Morphology in Patients with Parkinson's disease Using Optical Coherence Tomography” seeks to address how the development of Parkinson’s disease (PD) has a significant effect on the morphological aspect of the retina. The article was published in the journal PLOS One, Vol. 11 Issue 8, pg. 1-16 in August 2016. The article states the purpose of the study being conducted in a well-defined manner, which is to understand the structural changes that occur

    even during cardiac procedures. This innovation may even enable doctors to locate the correct location of unsafe unpredictable heart rhythms without intrusive biopsies. It could also help screen treatment. Fleming’s creation utilizes optical lucidness tomography (OCT), a craftsmanship that catches three-dimensional pictures of natural tissue. A particular catheter with a laser and little focal point near its tip is strung through the courses. At the point when the laser light reflects off the heart

On the other hand, elevated intraocular pressure, are not only risk factor of glaucoma .RNFL thickness measured by optical coherence tomography (OCT) is a reliable early marker of glaucoma[1,2]. As the pathogenesis of glaucoma involves the degeneration of axons as well as cell bodies and dendrites, The primary site of axonal damage in glaucoma is thought to be the lamina cribrosa

    4.1 GENERAL CONSIDERATIONS FOR POST-KERATOPLASTY REFRACTIVE SURGERY The corneal graft-host junction typically heals by 1 year after transplantation and corneal surface stability is achieved from 3 to 4 months after complete suture removal. However, this period can significantly vary due to patient's age, general health status (diabetes mellitus and collagen vascular disorders) and use of topical and systemic immunosuppressive medications. Given that, any surgical intervention for post-PKP astigmatism
