      Anterior Segment Optical Coherence Tomography for the Diagnosis of Corneal Dystrophies according to the IC3D Classification
      Corneal dystrophies are categorized according to the International Committee for Classification of Corneal Dystrophies (IC3D) classification, and their treatment depends on the affected structures and layer of the cornea. Therefore, estimating the depth and extent of the morphological changes due to the specific dystrophy is crucial when deciding between different treatment options. Besides superficial laser treatments and penetrating keratoplasty, minimal invasive lamellar keratoplasties such as Descemet membrane endothelial keratoplasty), deep ...

      Robust total retina thickness segmentation in optical coherence tomography images using convolutional neural networks
      We developed a fully automated system using a convolutional neural network (CNN) for total retina segmentation in optical coherence tomography (OCT) that is robust to the presence of severe retinal pathology. A generalized U-net network architecture was introduced to include the large context needed to account for large retinal changes. The proposed algorithm outperformed qualitative and quantitatively two available algorithms. The algorithm accurately estimated macular thickness with an error of ...

      Automated Staging of Age-Related Macular Degeneration Using Optical Coherence Tomography
      Purpose : To evaluate a machine learning algorithm that automatically grades age-related macular degeneration (AMD) severity stages from optical coherence tomography (OCT) scans. Methods : A total of 3265 OCT scans from 1016 patients with either no signs of AMD or with signs of early, intermediate, or advanced AMD were randomly selected from a large European multicenter database. A machine learning system was developed to automatically grade unseen OCT scans into different ...

      Intraoperative Optical Coherence Tomography in Lamellar Keratoplasties: Indications and Outcomes
      Purpose of Review Lamellar keratoplasties are evolving techniques to selectively replace diseased or opacified layers of the cornea. In recent years, the popularity of lamellar keratoplasties, especially Descemet membrane endothelial keratoplasty, Descemet stripping-automated endothelial keratoplasty and deep anterior lamellar keratoplasty, increased dramatically, since lamellar surgeries reduce intra- and postoperative complications and achieve faster visual recovery. Nonetheless, the surgical procedures are delicate. Recent Findings Novel imaging techniques, as intraoperative optical coherence ...

      Intraoperative Optical Coherence Tomography Ocular Surgery on a Higher Level or Just Nice Pictures?
      In recent years, optical coherence tomography (OCT) has developed into one of the most important imaging techniques in ophthalmology. Nonetheless, this technology is still evolving rapidly as recent developments in multimodal swept-source OCT devices and 4-dimensional real-time OCT demonstrate. Another currently developing sector in OCT application is the intraoperative use of OCT technology. Several approaches have been used to transfer OCT into an intraoperative setting, beginning with OCT-compatible positioning of ...
