Three Dimensional Spectral Domain Optical Coherence Topography in Ocular Toxoplasmosis
Delhi Journal of Ophthalmology, 2019 A 27 year old female presented with blurring of vision accompanied by floaters in her right eye one month back. On presentation, visual acuity was 20/400 in right eye and fundus examination showed two well defined chorioretinal atrophic scars, one ...

Virtual-OCT: A simulated optical coherence tomography instrument [PDF]
Journal of Innovative Optical Health Sciences, 2014 We report the virtual instrumentation of both time-domain (TD) and spectral-domain (SD) optical coherence tomography (OCT) systems. With a virtual partial coherence source from either a simulated or measured spectrum, the OCT signals of both A-scan and B-

Long wavelength optical coherence tomography for painted objects [PDF]
, 2013 Optical Coherence Tomography has been successfully applied to the imaging of painted objects in recent years. However, a significant limitation is the low penetration depth of OCT in paint because of the high opacity of paint due to either scattering or ...

Focal choroidal excavation on spectral domain-optical coherence tomography
Kerala Journal of Ophthalmology, 2019 We report the imaging characteristics of focal choroidal excavation (FCE) and associated choroidal neovascular membrane (CNVM) and interpret the probable etiopathogenesis of FCE through findings detected by multimodal imaging.

Normative Data and Minimally Detectable Change for Inner Retinal Layer Thicknesses Using a Semi-automated OCT Image Segmentation Pipeline [PDF]
, 2019 Neurodegenerative and neuroinflammatory diseases regularly cause optic nerve and retinal damage. Evaluating retinal changes using optical coherence tomography (OCT) in diseases like multiple sclerosis has thus become increasingly relevant.
