3. Expert-level Automated Biomarker Identification in Optical Coherence Tomography Scans
  
  Explore Nature Publishing Group Sep 24 2019 Ophthalmology
  
  In ophthalmology, retinal biological markers, or biomarkers , play a critical role in the management of chronic eye conditions and in the development of new therapeutics. While many imaging technologies used today can visualize these, Optical Coherence Tomography (OCT) is often the tool of choice due to its ability to image retinal structures in three dimensions at micrometer resolution. But with widespread use in clinical routine, and growing prevalence in chronic ...

8. In Vivo Imaging of Cx3cr1gfp/gfp Reporter Mice with Spectral-domain Optical Coherence Tomography and Scanning Laser Ophthalmoscopy
  
  Explore jove.com Nov 28 2017 Ophthalmology
  
  Spectral domain optical coherence tomography (SD-OCT) and scanning laser ophthalmoscopy (SLO) are extensively used in experimental ophthalmology. In the present protocol, mice expressing green fluorescent protein (gfp) under the promoter of Cx3cr1 (BALB/c-Cx3cr1 gfp/gfp ) were used to image microglia cells in vivo in the retina. Microglia are resident macrophages of the retina and have been implicated in several retinal diseases 1 , 2 , 3 , 4 , 5 , 6 . This protocol ...

12. Imaging of macrophage dynamics with optical coherence tomography in anterior ischemic optic neuropathy
  
  Explore ScienceDirect Dec 7 2016 Ophthalmology
  
  Anterior ischemic optic neuropathy (AION) is a relatively common cause of visual loss and results from hypoperfusion of the small arteries of the anterior portion of the optic nerve. AION is the leading cause of sudden optic nerve related vision loss with approximately 10 cases per 100000 in the population over 50 years. To date there is no established treatment for AION and therefore a better understanding of the events ...

15. Time-Resolved Ultra–High Resolution Optical Coherence Tomography for Real-Time Monitoring of Selective Retina Therapy
  
  Explore IOVS Journal Oct 27 2015 Ophthalmology
  
  Purpose : Selective retina therapy (SRT) is a novel treatment for retinal pathologies, solely targeting the RPE. During SRT, the detection of an immediate tissue reaction is challenging, as tissue effects remain limited to intracellular RPE photodisruption. Time-resolved ultra-high axial resolution optical coherence tomography (OCT) is thus evaluated for the monitoring of dynamic optical changes at and around the RPE during SRT. Methods : An experimental OCT system with an ultra-high axial ...
