    7. Optical coherence tomography angiography for detection of macular neovascularization associated with atrophy in age-related macular degeneration

      Optical coherence tomography angiography for detection of macular neovascularization associated with atrophy in age-related macular degeneration
      Purpose To evaluate the ability of optical coherence tomography angiography (OCTA) to detect macular neovascularization (MNV) in eyes with atrophy compared with fluorescein angiography (FA), indocyanine green angiography (ICGA), and optical coherence tomography (OCT). Methods In this prospective study, eyes with MNV and atrophy (termed macular atrophy or MA) secondary to age-related macular degeneration (AMD), and AMD eyes with geographic atrophy (GA) without MNV underwent multimodal imaging with FA, ICGA ...

    8. Optical coherence tomography angiography findings of fellow eye of proliferative macular telangiectasia type 2: Long term study

      Optical coherence tomography angiography findings of fellow eye of proliferative macular telangiectasia type 2: Long term study
      Purpose: To report the characteristics of non-proliferative fellow eyes in patients with unilateral proliferative macular telangiectasia type 2 (MacTel). Methods: This was a multicenter, retrospective study and included fellow eyes of eyes with subretinal neovascular membrane (SRNVM). Multimodal imaging including fundus photography, optical coherence tomography (OCT), and OCT angiography (OCTA) was performed. OCT and OCTA measurements included central macular thickness (CMT), subfoveal choroidal thickness (SFCT), foveal avascular zone (FAZ) area ...

    9. CHOROIDAL GRANULOMAS VISUALIZED BY SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      CHOROIDAL GRANULOMAS VISUALIZED BY SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY
      Purpose: To assess the visualization of choroidal granulomas with swept-source optical coherence tomography angiography (OCTA). Methods: Consecutive patients with granulomatous choroiditis due to tuberculosis, sarcoidosis, or VogtKoyanagiHarada disease underwent baseline OCTA images using a 12 12-mm field of view, and the choroidal slabs were analyzed by two independent examiners who counted the oval areas of flow void. Simultaneously, indocyanine green angiography (ICGA) and enhanced-depth imaging OCT were performed to mark ...

    10. Wavelength-encoded multi-channel spectral-domain optical coherence tomography (SD-OCT) for spatiotemporally resolved imaging

      Wavelength-encoded multi-channel spectral-domain optical coherence tomography (SD-OCT) for spatiotemporally resolved imaging
      In conventional SD-OCT, a beam is focused to one spot on the surface of the sample to acquire depth information beneath that spot. Adjacent spots are serially scanned to obtain a tomographic image of the sample; thus, available OCT techniques can take significant time to scan large objects. This paper illustrates an SD-OCT system involving spectral-slicing of a broadband spectrum to enable the simultaneous acquisition from multiple lateral positions of ...

    12. Optical coherence tomography diagnostic signs in posterior uveitis

      Optical coherence tomography diagnostic signs in posterior uveitis
      A diagnostic sign refers to a quantifiable biological parameter that is measured and evaluated as an indicator of normal biological, pathogenic, or pharmacologic responses to a therapeutic intervention. When used in translational research discussions, the term itself often alludes to a signs used to accelerate or aid in diagnosis or monitoring and provide insight into personalized medicine. Many new diagnostic signs are being developed that involve imaging technology. Optical coherence ...
