2. Machine learning helps improve diagnostic ability of subclinical keratoconus using Scheimpflug and OCT imaging modalities
  
  Explore Eye and Vision 9 hours, 26 min ago Ophthalmology
  
  Purpose To develop an automated classification system using a machine learning classifier to distinguish clinically unaffected eyes in patients with keratoconus from a normal control population based on a combination of Scheimpflug camera images and ultra-high-resolution optical coherence tomography (UHR-OCT) imaging data. Methods A total of 121 eyes from 121 participants were classified by 2 cornea experts into 3 groups: normal (50 eyes), with keratoconus (38 eyes) or with subclinical ...

5. Widefield Swept-Source OCTA in Vogt-Koyanagi-Harada Disease
  
  Explore Healio.com Jul 29 2020 Ophthalmology
  
  Herein, the authors describe an initial case report of widefield swept-source optical coherence tomography angiography (SS-OCTA) in Vogt-Koyanagi-Harada (VKH) disease. When compared to fluorescent angiography, indocyanine green angiography, and enhanced-depth OCT upon which the revised criteria for VHK are based widefield SS-OCTA enables detection of vitreous inflammation, noninvasive identification of characteristic areas of flow void at the level of choriocapillaris in the acute phase and may be a novel valuable ...

8. The precision and agreement of corneal thickness and keratometry measurements with SS-OCT versus Scheimpflug imaging
  
  Explore Eye and Vision Jun 13 2020 Ophthalmology
  
  Purpose To assess the repeatability and reproducibility of swept-source optical coherence tomography (SS-OCT) and Scheimpflug system and evaluate the agreement between the two systems in measuring multiple corneal regions in children. Methods Pachymetric and keratometric maps for both systems were evaluated. Central, midperipheral and peripheral corneal thickness (CT), keratometry and astigmatism power vectors were recorded. The three outcomes yielded by the same observer were used to assess intraobserver repeatability. The ...

  Background To quantitatively assess anterior chamber angle (ACA) structure by anterior segment optical coherence tomography (AS-OCT) and develop a model to evaluate angle width as defined by gonioscopy. Methods The ACAs of each quadrant were evaluated by gonioscopy, classified by the Scheie grading system, and assigned into one of the three grades: small angle (SA), moderate angle (MA), and large angle (LA). The eyes were imaged by AS-OCT, and ACA ...
