    7. Pearls and Pitfalls of Optical Coherence Tomography Angiography Imaging: A Review

      Pearls and Pitfalls of Optical Coherence Tomography Angiography Imaging: A Review
      Optical coherence tomography angiography (OCTA) has significantly expanded our knowledge of the ocular vasculature. Furthermore, this imaging modality has been widely adopted to investigate different ocular and systemic diseases. In this review, a discussion of the fundamental principles of OCTA is followed by the application of this imaging modality to study the retinal and choroidal vessels. A proper comprehension of this imaging modality is essential for the interpretation of OCTA ...

    8. One-Year Outcome Predictors of Strabismus Surgery from Anterior Segment Optical Coherence Tomography with Multiple B-Scan Averaging

      One-Year Outcome Predictors of Strabismus Surgery from Anterior Segment Optical Coherence Tomography with Multiple B-Scan Averaging
      Strabismologists are eager to identify preoperative or intraoperative strabismus surgery outcome predictors because of the variable effects in each patient. Conjunctival closure position recession after rectus muscle recession is effective for correcting large angle strabismus. The elasticity of the conjunctiva and Tenons capsule is important for strabismus surgery management. In this longitudinal study, we evaluated the prognosis of conjunctiva and Tenons capsule thickness (CTT) near the limbus 1 year after ...

    9. Diabetic Nonperfused Areas in Macular and Extramacular Regions on Wide-Field Optical Coherence Tomography Angiography

      Diabetic Nonperfused Areas in Macular and Extramacular Regions on Wide-Field Optical Coherence Tomography Angiography
      Purpose : To investigate the nonperfused areas (NPAs) in each subfield segmented by large arterioles on wide-field swept-source optical coherence tomography angiography (SS-OCTA) images in diabetic retinopathy. Methods : We retrospectively reviewed 101 consecutive eyes of 67 patients with severe nonproliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR), for whom 12 12-mm SS-OCTA images centered on the optic disc were acquired. Both eyes were included in 34 patients. NPAs in the ...

Methods : Macular areas measuring 464 464 pixels of 10 right eyes of 10 healthy subjects without ocular disease were scanned 10 times using a HR-OCTA device. Averaged OCTA images were created. Based on clear decorrelation signals, four vascular slabs were segmented, comprising one ...

    11. Direct comparison of optical coherence tomography and high-definition 60-MHz intravascular ultrasound imaging of intra-procedural stent thrombosis in a patient with acute coronary syndrome

      Direct comparison of optical coherence tomography and high-definition 60-MHz intravascular ultrasound imaging of intra-procedural stent thrombosis in a patient with acute coronary syndrome
      An 80-year-old man with ST-segment elevation myocardial infraction underwent coronary stenting using an everolimus-eluting stent, which resulted in a good coronary flow with no residual stenosis. However, 10 min after final coronary angiography, the patient complained of chest discomfort and the ECG again showed ST elevation. Repeat coronary angiography revealed multiple contrast filling defects in the stent. High-definition 60-MHz intravascular ultrasound (IVUS) examination showed multiple low echoic structures inside the ...

      The image depicts a 60-year-old woman with bilateral cataracts and no history of amblyopia, strabismus, or systemic diseases. Color slitlamp photography of the left eye ( Figure , A) showed a persistent pupillary membrane, with multiple iris strands extending from collarette to collarette and adhering to the anterior lens surface. Anterior segment optical coherence tomography angiography ( Figure , B) showed vessels originating from the lesser arterial circle of the iris and anastomosing with ...

      Visualization of the Lamina Cribrosa Microvasculature in Normal and Glaucomatous Eyes: A Swept-source Optical Coherence Tomography Angiography Study
      Purpose: The purpose of this study was to investigate the lamina cribrosa (LC) microvasculature using swept-source (SS) optical coherence tomography angiography (OCTA) images that have been processed using multiple image averaging and a projection-resolved algorithm. OCTA has recently gained popularity for assessing retinal and choroidal microvasculature . However, it is not known if the LC microvasculature , which likely holds important information for further understanding of glaucoma , can be visualized with OCTA ...

      Swept-Source Optical Coherence Tomography Angiography of Microaneurysms in Myopic Retinoschisis
      A woman in her early 30s presented with floaters that had been present for several years. Her best-corrected visual acuity was 1.5 (20/13) OU. Axial length was 27.93 mm OD and 27.35 mm OS. Numerous aneurysms were observed temporal to the macula, predominantly in the left eye ( Figure , A). Swept-source optical coherence tomography angiography confirmed that these aneurysms were located in the retinoschisis cavity ( Figure , B ...
