Swept source: optical coherence tomography angiography features of choroidal osteoma with choroidal neovascular membrane.
To cite: Azad SV, Takkar B, Venkatesh P, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016215899 DESCRIPTION A 16-year-old boy presented with best-corrected visual acuity of 6/18 OD. OS was within normal limits, as was anterior segment OD. A focal whitish-yellow plaque lesion with overlying areas of depigmentation, and retinal atrophy in the central and ...
متن کاملChoroidal Imaging with Swept Source Optical Coherence Tomography – A Review
The choroid provides up to 70 % of blood and oxygen to the eye. Pathological changes of this vascular tissue may lead to malnutrition of the retina and therefore be involved in the pathogenesis of numerous retinal disorders. Swept source optical coherence tomography (SS-OCT) is a new development of a non-invasive imaging technique that uses a tunable laser source with a higher wavelength light ...
متن کاملPolypoidal Choroidal Vasculopathy on Swept-Source Optical Coherence Tomography Angiography with Variable Interscan Time Analysis
Purpose To use a novel optical coherence tomography angiography (OCTA) algorithm termed variable interscan time analysis (VISTA) to evaluate relative blood flow speeds in polypoidal choroidal vasculopathy (PCV). Methods Prospective cross-sectional study enrolling patients with confirmed diagnosis of PCV. OCTA of the retina and choroid was obtained with a prototype swept-source OCT system. The...
متن کاملImaging choroidal neovascular membrane using en face swept-source optical coherence tomography angiography
PURPOSE The aim of this study was to assess the efficacy of swept-source optical coherence tomography angiography (SS-OCTA) in delineating the morphology of choroidal neovascular membrane (CNV). PATIENTS AND METHODS This was a retrospective observational case series reviewing clinical data and fundus fluorescein angiography (FFA), swept-source optical coherence tomography (SS-OCT), and SS-OCT...
متن کاملSwept-source optical coherence tomography angiography for choroidal neovascularization after bevacizumab and photodynamic therapy
Purpose To report the swept-source optical coherence tomography angiography (SS-OCTA) findings after bevacizumab anti-vascular endothelial growth factor (anti-VEGF) and full-fluence photodynamic therapy (PDT) for choroidal neovascularization. Design Case report. Methods An 87-year-old, Chinese male presented with a shadow and decreased vision to 20/160 in his left eye (OS). Clinical examina...
