    2. Optical coherence tomography of Bitot’s spot in vitamin A deficiency

      Optical coherence tomography of Bitot’s spot in vitamin A deficiency
      Background Severe vitamin A deficiency can manifest as xerophthalmia in the eyes resulting in clinical features, such as night blindness, conjunctival xerosis, corneal xerosis, corneal ulcers and Bitots spots. We present the multimodal imaging results of a patient who underwent an ileocecal resection for Crohns disease and presented with nyctalopia and bilateral central scotomas. Method Report of a single case. Results The patients best-corrected visual acuity was 20/50 in ...

    3. Swept-Source OCT Visualization of Macular Hole Closure in Gas-Filled Eyes

      Swept-Source OCT Visualization of Macular Hole Closure in Gas-Filled Eyes
      BACKGROUND AND OBJECTIVE: To assess the utility of swept-source optical coherence tomography (SS-OCT) in visualizing macular hole (MH) closure through gas-filled eyes on postoperative day (POD) 1 using a dual scanning protocol. PATIENTS AND METHODS: We examined 30 consecutive patients with full-thickness MH who underwent standard vitrectomy with SF6 (25%) gas tamponade between July 2015 and April 2016. SS-OCT imaging was performed using horizontal raster and 16-line radial scans with ...

    4. Swept-Source Optical Coherence Tomography Angiography and Vascular Perfusion Map Findings in Obstructive Sleep Apnea

      Swept-Source Optical Coherence Tomography Angiography and Vascular Perfusion Map Findings in Obstructive Sleep Apnea
      Obstructive sleep apnea (OSA) is a highly prevalent chronic sleep disorder associated with considerable systemic and ophthalmic consequences. The authors present the retinal vascular findings of a visually asymptomatic 56-year-old man clinically diagnosed with OSA using swept-source optical coherence tomography and vascular perfusion mapping.

    5. Optical Coherence Tomography Angiography Findings in Coats' Disease

      Optical Coherence Tomography Angiography Findings in Coats' Disease
      BACKGROUND AND OBJECTIVE: To describe optical coherence tomography angiography (OCTA) findings in patients with unilateral Coats' disease. PATIENTS AND METHODS: Retrospective, observational case series of four patients with unilateral Coats' disease who underwent bilateral OCTA imaging. RESULTS: Bilateral macular OCTA findings of eight eyes are described. An abnormal foveal avascular zone (FAZ) with inner retinal vessels traversing the avascular zone in the superficial capillary plexus was visible on OCTA in ...

    6. Cataractous mountain on the corneal horizon: Swept-source optical coherence tomography

      Cataractous mountain on the corneal horizon: Swept-source optical coherence tomography
      Anterior segment optical coherence tomography (AS-OCT) resolves ocular structures to a degree comparable to that of ultrasound (US) biomicroscopy; in some cases, such as visualization of the scleral spur, AS-OCT provides superior images.1 Swept-source AS-OCT is based on time-encoded Fourier-domain OCT technology anduses a rapidly tunable laser light source.

    7. Ultra-Widefield Steering-Based Spectral-Domain Optical Coherence Tomography Imaging of the Retinal Periphery

      Ultra-Widefield Steering-Based Spectral-Domain Optical Coherence Tomography Imaging of the Retinal Periphery
      Purpose To describe the spectral-domain optical coherence tomography (SD OCT) features of peripheral retinal findings using an ultra-widefield (UWF) steering technique to image the retinal periphery. Design Observational study. Participants A total of 68 patients (68 eyes) with 19 peripheral retinal features. Main Outcome Measures Spectral-domain OCTbased structural features. Methods Nineteen peripheral retinal features, including vortex vein, congenital hypertrophy of the retinal pigment epithelium, pars plana, ora serrata pearl, typical ...

    8. ENHANCED DEPTH IMAGING SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY FEATURES OF LIGHT CHAIN DEPOSITION DISEASE

      ENHANCED DEPTH IMAGING SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY FEATURES OF LIGHT CHAIN DEPOSITION DISEASE
      Purpose: To describe a previously unreported finding in the choroid of a patient with light chain deposition disease on enhanced depth imaging optical coherence tomography. Methods: Clinical examination, fundus photography, fundus autofluorescence, fluorescein angiography, indocyanine green angiography, and spectral domain enhanced depth imaging optical coherence tomography were performed in a patient with light chain deposition disease. Results: This 45-year-old white man presented with decreased vision in both eyes. Clinical examination ...

    9. Spectral Domain Optical Coherence Tomography Findings in Patients With Acute Syphilitic Posterior Placoid Chorioretinopathy

      Spectral Domain Optical Coherence Tomography Findings in Patients With Acute Syphilitic Posterior Placoid Chorioretinopathy
      Purpose: To describe the appearance of acute syphilitic posterior placoid chorioretinitis, a rare ocular manifestation of syphilis, on spectral domain optical coherence tomography (SD OCT) both before and after treatment. Methods: Ophthalmic examination and imaging studies of 30 eyes of 19 confirmed cases were analyzed both at the time of presentation and at each follow-up visit. Patients with SD OCT and fluorescein angiography at the time of presentation, and at ...
