Wavelength-swept lasers and their application to fiber optic sensors

The wavelength swept laser (WSL) is a promising optical source in optical coherence tomography, optical fiber sensor, and optical beat source generation. It is demonstrated by employing a narrowband wavelength-scanning filter, such as a fast rotating polygonal-scanner-filter, a diffraction grating …

Spectral-Domain Optical Coherence Tomography of Sympathetic Ophthalmia With Dalen-Fuchs Nodules

The authors present a case of sympathetic ophthalmia with Dalen–Fuchs nodules visualized with spectral-domain optical coherence tomography (SD-OCT). An 84-year-old man presented with floaters and decreased vision 25 years after penetrating trauma to the fellow eye. Examination revealed vitritis and …

Identification of vessel wall degradation in ascending thoracic aortic aneurysms with OCT

Degradation of the wall of human ascending thoracic aorta has been assessed through Optical Coherence Tomography (OCT). OCT images of the media layer of the aortic wall exhibit micro-structure degradation in case of diseased aortas from aneurysmal vessels. The OCT …

Serial Spectral Domain Ocular Coherence Tomography Measurement of Outer Nuclear Layer Thickness in Rhegmatogenous Retinal Detachment Repair

Introduction : The outer nuclear layer (ONL) contains mostly photoreceptor bodies and reduced post-operative ONL thickness (ONLT) is associated with poor visual outcome in rhegmatogenous retinal detachment (RRD). Methods : Spectral domain ocular coherence tomography was recorded before and 6 …

Retinal neurodegeneration on optical coherence tomography and cerebral atrophy

Neurodegeneration in dementia is mainly evaluated by assessing cerebral atrophy, while retinal neurodegeneration can be quantified in vivo using optical coherence tomography (OCT). We examined the association of retinal nerve fibre layer (RNFL) and ganglion cell-inner plexiform layer (GC–IPL) thinning …
