Optical Coherence Tomography Angiography and High Myopia
High myopia, defined as spherical equivalent > 6 diopters (D) or axial length greater than 26.5 mm, is a major cause of visual impairment and blindness.1,2,3,4 In high myopia, progressive…
Optical Coherence Tomography Angiography and Arterial Occlusions
Central retinal artery occlusion (CRAO) presents as sudden, catastrophic visual loss and is therefore, one of the most important topics in ophthalmology. Similarly, branch retinal arterial, or better termed arteriolar,…
Current Optical Coherence Tomography Angiography Clinical Systems
Optovue AngioVue The underlying technology of the Optovue AngioVue system is the Avanti SDOCT wide-field imaging system. The Avanti system utilizes an 840-nm light source with a bandwidth of 50…
Optical Coherence Tomography Angiography and Diabetic Retinopathy
Pericyte loss, microaneurysm formation, breakdown of the blood–retinal barrier, and capillary nonperfusion impair the nutrition of the neuroglial tissues in the retinal parenchyma, and the resultant hypoxia increases expression of…
Optical Coherence Tomography Angiography and Uveitis
Uveitis is an umbrella term for a variety of inflammatory eye conditions. It is a major cause of severe visual impairment worldwide and affects not only the uvea but also…
Optical Coherence Tomography Angiography in Macular Telangiectasia Type 2
Introduction Macular telangiectasia type 2 (MacTel2) is a progressive neurogliovascular macular dystrophy starting in the fifth decade of life and evolving progressively toward macular atrophy.1 When the disease becomes symptomatic,…
Optical Coherence Tomography Angiography in Retinal Venous Occlusions
Retinal venous occlusive disease (RVO) is characterized by vascular changes, which include dilation and engorgement of central or branch retinal veins, retinal hemorrhages, accumulation of intraretinal or subretinal fluid, and…
Optical Coherence Tomography Angiography and Neovascular Age-Related Macular Degeneration
Fundus fluorescein angiography (FA), the current gold standard for diagnosing neovascular AMD, is an invasive dye-based imaging modality that requires an intravenous administration of contrast followed by interval fundus photography…
Optical Coherence Tomography Angiography and Central Serous Chorioretinopathy
Central serous chorioretinopathy (CSC) is a disorder characterized by serous detachment of the neurosensory retina, sometimes accompanied by retinal pigment epithelium (RPE) detachment.1,2 The serous detachment is caused by leakage…
The Future of Optical Coherence Tomography Angiography
Spectral Domain and Swept-Source Optical Coherence Tomography Optical coherence tomography angiography (OCTA), with the ability to visualize vasculature in vivo without the injection of dye, represents an exciting advancement in…
