Optical Coherence Tomography Angiography of Two Choroidal Nevi Variants
Optical coherence tomography angiography (OCT-A) is a recently established noninvasive technology for evaluation of the retinal and choroidal vasculature. The literature regarding the findings in choroidal nevi is scarce. We report the OCT-A findings associated with two different variants. Subject one had decreased vascular flow signal in the choroidal, choriocapillaris, deep retinal, and super...
متن کاملUse of OCT Angiography in Choroidal Melanocytic Tumors
Objective To describe OCTA findings in choroidal melanocytic tumors, especially the microcirculation patterns, and to try to correlate with the histopathological studies. Methods Cross-sectional, comparative, observational study. 70 cases, including 55 choroidal nevi and 15 choroidal melanomas. Three different observers evaluated specific variables in the choriocapillaris layer on AOCT images...
متن کاملChoriocapillaris and Choroidal Microvasculature Imaging with Ultrahigh Speed OCT Angiography
We demonstrate in vivo choriocapillaris and choroidal microvasculature imaging in normal human subjects using optical coherence tomography (OCT). An ultrahigh speed swept source OCT prototype at 1060 nm wavelengths with a 400 kHz A-scan rate is developed for three-dimensional ultrahigh speed imaging of the posterior eye. OCT angiography is used to image three-dimensional vascular structure with...
متن کاملChoroidal Nevus-Associated Neovascular Membrane Demonstrated by OCT Angiography
We present a case of choroidal nevus, complicated by a choroidal neovascular membrane (CNV) that was detected by OCT angiography. Choroidal nevi are relatively common intraocular tumors. The presence of subretinal and intraretinal fluids can indicate that a CNV has occurred as a complication, warranting prompt management. However, subretinal and intraretinal fluids are also documented in nevi w...
متن کاملOptical coherence tomography angiography in choroidal melanoma and nevus
Synopsis In optical coherence tomography angiography, the choroidal vascular flow rate in choroidal melanoma is significantly lower than that in choroidal nevus. Objective The objective of this study was to describe the choriocapillaris and retinal features imaged by optical coherence tomography angiography (OCTA) in eyes with choroidal nevus from small malignant choroidal melanoma. Methods...
