    2. Looking Outside The Maculaa Wide-Field Optical Coherence Tomography Study

      Looking Outside The Maculaa Wide-Field Optical Coherence Tomography Study
      Purpose: To evaluate baseline features and morphologic changes of vitreoretinal adhesion and outer retinal layers outside the macula after intravitreal ocriplasmin injection. To study the relation between vitreous detachment and attenuation of retinal outer segments signal. Methods: Retrospective cases series of 15 eyes. Each eye was scanned with the 55 wide-field optical coherence tomography lens in 6 different locations, three horizontal B-scan (central, temporal, and nasal) and three vertical B-scan ...

    3. In Vivo Vibration Measurement of Middle Ear Structure Using Doppler Optical Coherence Tomography: Preliminary Study

      In Vivo Vibration Measurement of Middle Ear Structure Using Doppler Optical Coherence Tomography: Preliminary Study
      Objectives Doppler optical coherence tomography (DOCT) is useful for both, the spatially resolved measurement of the tympanic membrane (TM) oscillation and high-resolution imaging. We demonstrated a new technique capable of providing real-time two-dimensional Doppler OCT image of rapidly oscillatory latex mini-drum and in vivo rat TM and ossicles. Methods Using DOCT system, the oscillation of sample was measured at frequency range of 14 kHz at an output of 15 W ...

    4. Imaging the Deep Choroidal Vasculature Using Spectral Domain and Swept Source Optical Coherence Tomography Angiography

      Imaging the Deep Choroidal Vasculature Using Spectral Domain and Swept Source Optical Coherence Tomography Angiography
      Purpose: To evaluate the deeper choroidal vasculature in eyes with various ocular disorders using spectral domain (SD) optical coherence tomography angiography (OCTA) and swept source (SS) OCTA. Methods: Patients underwent OCTA imaging with either SD-OCTA (Zeiss Cirrus Angioplex or Optovue AngioVue) or SS-OCTA (Topcon Triton). Retinal pigment epithelium (RPE) integrity, structural visualization of deep choroidal vessels on en face imaging, and OCTA of deep choroidal blood flow signal were analyzed ...

    5. Evaluation of choroidal lesions with swept-source optical coherence tomography

      Evaluation of choroidal lesions with swept-source optical coherence tomography
      Aims The aim of our study was to image choroidal lesions with swept-source optical coherence tomography (SS-OCT) and to identify the morphological characteristics associated with optimal visualisation. Methods This was a prospective, cross-sectional study. Patients with choroidal melanocytic lesions 3mm in thickness on B-scan ultrasonography were recruited. All participants underwent SS-OCT. On SS-OCT we evaluated qualitative (eg, lesion outline, detection of scleral-choroidal interface and quality of the image) and quantitative ...

    6. Double Optic Disc Pit With Glial Plugs Imaged by Wide-Field Optical Coherence Tomography

      Double Optic Disc Pit With Glial Plugs Imaged by Wide-Field Optical Coherence Tomography
      A rare case of a woman in her thirties with double optic disc pits involving opposing sectors is reported. Significantly decreased vision due to macular schisis was noted. Wide-field optical coherence tomography revealed distinct laminar defects and glial tufts associated with each pit. This case illustrates a rare view into the pathogenesis of optic disc pits.

    7. Optical coherence tomographic angiography identifies peripapillary microvascular dilation and focal non-perfusion in giant cell arteritis

      Optical coherence tomographic angiography identifies peripapillary microvascular dilation and focal non-perfusion in giant cell arteritis
      Aims We set out to determine the optical coherence tomographic angiography (OCT-A) characteristics of arteritic anterior ischaemic optic neuropathy (AAION) in the context of giant cell arteritis (GCA). Methods This is an observational case series of four patients with AAION secondary to GCA, three with unilateral AAION and one with bilateral AAION. We reviewed the charts, fundus photography, visual fields, fluorescein angiography (FA) and OCT-A images for all patients to ...

    8. Optical coherence tomography findings and successful repair of retina detachment in Knobloch syndrome

      Optical coherence tomography findings and successful repair of retina detachment in Knobloch syndrome
      A 7-year-old Afghani girl was referred to the retina clinic of Massachusetts Eye and Ear for a chronic-appearing, macula-off retinal detachment in the left eye. On examination, best-corrected visual acuity was 20/400 in the right eye and 20/800 in the left eye. She had bilateral horizontal nystagmus. Ophthalmoscopy revealed prominent choroidal vessels, chorioretinal atrophy in the macular area, attenuated retinal vasculature, and pale optic discs bilaterally. Spectral domain ...

    9. Congenital anomalies of the optic disc: insights from optical coherence tomography imaging

      Congenital anomalies of the optic disc: insights from optical coherence tomography imaging
      Purpose of review Congenital anomalies of the optic nerve are rare but significant causes of visual dysfunction in children and adults. Accurate diagnosis is dependent on a thorough funduscopic examination, but can be enhanced by imaging information garnered from optical coherence tomography (OCT). We review common congenital optic nerve anomalies, including optic disc pit, optic nerve coloboma, morning glory disc anomaly, and hypoplasia of the optic nerve, review their systemic ...

    10. Volumetric Measurement of Optic Nerve Head Drusen Using Swept-Source Optical Coherence Tomography

      Volumetric Measurement of Optic Nerve Head Drusen Using Swept-Source Optical Coherence Tomography
      Purpose: To describe new software tools for quantifying optic nerve head drusen volume using 3-dimensional (3D) swept-source optical coherence tomography (SS-OCT) volumetric scans. Materials and Methods: SS-OCT was used to acquire raster volume scans of 8 eyes of 4 patients with bilateral optic nerve head drusen. The scans were manually segmented by 3 graders to identify the drusen borders, and thereafter total drusen volumes were calculated. Linear regression was performed ...

      Retinal Loop Vessel Captured with Optical Coherence Tomography-Angiography
      A 50-year-old woman with a history of rheumatoid arthritis and macular hydroxychloroquine toxicity presented for a routine eye examination. An incidental loop vessel of the inferior prepapillary arteriole was readily apparent on examination (Fig 1 A ). Three-dimensional optical coherence tomography (OCT; Avanti, Optovue, Fremont, CA) demonstrated the elevation of this vessel into the vitreous (Fig 1 B ). The vessel was also captured on OCT-angiography (Fig 1 C ) with segmentation of ...

    13. Focal Capillary Dropout Associated With Optic Disc Drusen Using Optical Coherence Tomographic Angiography

      Focal Capillary Dropout Associated With Optic Disc Drusen Using Optical Coherence Tomographic Angiography
      Optic disc drusen may be a cause of visual field defects and visual loss. The mechanism by which this occurs is unclear. We report a patient who developed decreased vision in the right eye and was found to have a heavy burden of superficial optic disc drusen. Optical coherence tomography (OCT) confirmed focal retinal nerve fiber layer thinning that corresponded with the distribution of drusen. OCT angiography, with superficial laminar ...
