Journal of International Medical Research, 2013 Objective To determine the value of optic disc parameters and perimetric defects in the early diagnosis of patients with primary open-angle glaucoma (POAG). Methods Optic disc parameters and perimetry were compared among patients in the early stage of POAG, patients with suspected POAG and healthy control subjects, using Heidelberg retina tomography ...

Arterial macroaneurysm of the optic disc
American Journal of Ophthalmology Case Reports, 2018 Purpose: We present fundus and spectral domain optical coherence tomography findings of a patient with an arterial macroaneurysm of the optic disc. Observations: An 87-year-old woman presented with blurry vision and was found to have a retinal arterial ...

Inverse scattering problem for optical coherence tomography [PDF]
, 2003 We deal with the imaging problem of determining the internal structure of a body from backscattered laser light and low-coherence interferometry. Specifically, using the interference fringes that result when the backscattering of low-coherence light is ...

Optical coherence tomography angiography
Progress in retinal and eye research, 2017 Optical coherence tomography (OCT) was one of the biggest advances in ophthalmic imaging. Building on that platform, OCT angiography (OCTA) provides depth resolved images of blood flow in the retina and choroid with levels of detail far exceeding that ...

Cross-Polarized Optical Coherence Tomography System with Unpolarized Light
Photonics, 2022 Cross-polarized optical coherence tomography offers improved contrast for samples which can alter the polarization of light when it interacts with the sample. This property has been utilized to screen pathological conditions in several organs.

Optical coherence tomography and scanning laser ophthalmoscopy: Approaches to dual-channel retinal tissue imaging [PDF]
, 2014 We report a Talbot bands-based optical coherence tomography (OCT) system capable of producing longitudinal B-scan OCT images and en-face scanning laser ophthalmoscopy (SLO) images of the human retina in-vivo, with various degrees of ...

An overview of optical coherence tomography angiography and the posterior pole
Therapeutic Advances in Ophthalmology, 2019 Optical coherence tomography angiography is a relatively new, noninvasive technology that has revolutionized imaging of the retinal and choroidal microvasculature. This technology is based on the detection of movement or changes that represent moving red

Optical tomography dynamics induced by qubit-resonator interaction under intrinsic decoherence
Scientific Reports, 2022 A superconducting circuit with a qubit and a resonator coupled via a two-photon interaction is considered. When the resonator is initially in a superposition of coherent states, optical tomography and quantum coherence dynamics are examined in the ...
