2. Multi-modal and multi-scale clinical retinal imaging system with pupil and retinal tracking
  
  Explore Nature Publishing Group Jun 11 2022 Ophthalmology
  
  We present a compact multi-modal and multi-scale retinal imaging instrument with an angiographic functional extension for clinical use. The system integrates scanning laser ophthalmoscopy (SLO), optical coherence tomography (OCT) and OCT angiography (OCTA) imaging modalities and provides multi-scale fields of view. For high resolution, and high lateral resolution in particular, cellular imaging correction of aberrations by adaptive optics (AO) is employed. The entire instrument has a compact design and the ...

  Explore Optical Coherence Tomography News May 28 2022
  
  Dear Colleagues, Since its invention in 1991, optical coherence tomography (OCT) has rapidly become one of the most important clinical tools in the field of ophthalmology. In recent years, applications of this inherently non-invasive and label-free three-dimensional imaging technique have extended far beyond retinal and corneal imaging. OCT applications are being increasingly used in medicine in fields including dermatology, endoscopy and neurology, and advances in system technology and image processing ...

5. The New Era of Retinal Imaging in Hypertensive Patients
  
  Explore LWW Online May 10 2022 Ophthalmology
  
  Structural and functional alterations in the microcirculation by systemic hypertension can cause significant organ damage at the eye, heart, brain, and kidneys. As the retina is the only tissue in the body that allows direct imaging of small vessels, the relationship of hypertensive retinopathy signs with development of disease states in other organs have been extensively studied; large-scale epidemiological studies using fundus photography and advanced semi-automated analysis software have reported ...

7. A multi-regression approach to improve optical coherence tomography diagnostic accuracy in multiple sclerosis patients without previous optic neuritis
  
  Explore ScienceDirect Apr 22 2022 Ophthalmology
  
  Background: Optical coherence tomography (OCT) is a retinal imaging system that may improve the diagnosis of multiple sclerosis (MS) persons, but the evidence is currently equivocal. To assess whether compensating the peripapillary retinal nerve fiber layer (pRNFL) thickness for ocular anatomical features as well as the combination with macular layers can improve the capability of OCT in differentiating non-optic neuritis eyes of relapsing-remitting MS patients from healthy controls. Methods: 74 ...

8. Evaluation of neuroretinal integrity in optical coherence tomography-graded eyes with partial-thickness macular holes
  
  Explore Wiley Online Library Apr 12 2022 Ophthalmology
  
  Purpose: To evaluate neuroretinal integrity in different subtypes of optical coherence tomography (OCT)-graded partial-thickness macular holes. Methods: Fovea-centred SD-OCT images (Cirrus, Carl Zeiss Meditec AG; Spectralis, Heidelberg Engineering GmbH) and visual acuity (VA) acquired at every visit were analysed by two retina specialists retrospectively in 71 eyes of 65 patients. Partial-thickness macular holes were classified as lamellar macular hole (LMH), epiretinal membrane foveoschisis (ERMF) or macular pseudohole (MPH). Results ...

  The aim of this study is to show that the Nd:YAG laser could be a promising alternative treatment option in the management of low-risk basal cell carcinomas with similar high efficacy rates to surgery, and low recurrence rates evaluated over a time period of one year. Reflectance confocal microscopy, optical coherence tomography and clinical examination are used prior to confirm the clinical diagnosis of the basal cell carcinoma and ...

10. Robust Fovea Detection in Retinal OCT Imaging using Deep Learning
  
  Explore IEEE Xplore Apr 11 2022 Ophthalmology
  
  The fovea centralis is an essential landmark in the retina where the photoreceptor layer is entirely composed of cones responsible for sharp, central vision. The localization of this anatomical landmark in optical coherence tomography (OCT) volumes is important for assessing visual function correlates and treatment guidance in macular disease. In this study, the "PRE U-net" is introduced as a novel approach for a fully automated fovea centralis detection, addressing the ...

11. Non-destructive characterization of adult zebrafish models using Jones matrix optical coherence tomography
  
  Explore Optica Publishing Group Mar 30 2022 Developmental Biology
  
  The zebrafish is a valuable vertebrate animal model in pre-clinical cancer research. A Jones matrix optical coherence tomography (JM-OCT) prototype operating at 1310 nm and an intensity-based spectral-domain OCT setup at 840 nm were utilized to investigate adult wildtype and a tumor-developing zebrafish model. Various anatomical features were characterized based on their inherent scattering and polarization signature. A motorized translation stage in combination with the JM-OCT prototype enabled large field-of-view ...

  Background Diagnostic performance of optical coherence tomography (OCT) to detect Alzheimers disease (AD) and mild cognitive impairment (MCI) remains limited. We assessed whether compensating the circumpapillary retinal nerve fiber layer (cpRNFL) thickness for multiple demographic and anatomical factors as well as the combination of macular layers improves the detection of MCI and AD. Methods This cross-sectional study of 62 AD ( n =92 eyes), 108 MCI ( n =158 eyes), and 55 ...
