    2. Robust total retina thickness segmentation in optical coherence tomography images using convolutional neural networks

      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 ...

    3. Automated Staging of Age-Related Macular Degeneration Using Optical Coherence Tomography

      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 ...

    4. Intraoperative Optical Coherence Tomography in Lamellar Keratoplasties: Indications and Outcomes

      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 ...

      Spectral-domain optical coherence tomography findings of the macula in 500 consecutive patients with uveitis
      Purpose To analyze the macular structure in a large series of consecutive patients with different types of uveitis using spectral-domain optical coherence tomography (SD-OCT). Patients and methods Five hundred eyes of 500 consecutive patients with anterior, intermediate, posterior, and panuveitis underwent standardized macular examination using SD-OCT. Central retinal thickness (CRT), macular volume (MV), and presence of cystoid macular edema (CME), diffuse macular edema (DME), serous retinal detachment (SRD), epiretinal membrane ...

    8. Neuroretinal rim in non-glaucomatous large optic nerve heads: a comparison of confocal scanning laser tomography and spectral domain optical coherence tomography

      Neuroretinal rim in non-glaucomatous large optic nerve heads: a comparison of confocal scanning laser tomography and spectral domain optical coherence tomography
      Background/aims To compare margin-based rim area measurements from confocal scanning laser tomography (CSLT) with Bruch's membrane opening (BMO)-based measurements from spectral domain optical coherence tomography (SD-OCT) by analysis of a group of non-glaucomatous eyes with large optic discs, so-called macrodiscs (disc size 2.45 mm 2 in CSLT). Objective is to create a reference base for large optic nerve heads in SD-OCT diagnostics. Methods 102 eyes received ...

    9. Intraoperative Optical Coherence Tomography Enables Noncontact Imaging During Canaloplasty

      Intraoperative Optical Coherence Tomography Enables Noncontact Imaging During Canaloplasty
      Purpose: Here we describe intraoperative optical coherence tomography (iOCT) as a novel noncontact imaging tool for intraoperative monitoring and procedure evaluation during canaloplasty, as a nonpenetrating surgical technique to treat primary open angle glaucoma. Materials and Methods: Retrospective case report of a patient (63 y, female), who underwent traditional canaloplasty, using a commercially available 840 nm OCT device, mounted to an operating microscope (Rescan 700). Main outcome measures were the ...

    10. Intraoperative Optical Coherence Tomography Ocular Surgery on a Higher Level or Just Nice Pictures?

      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 ...

      Future Prospects: Assessment of Intraoperative Optical Coherence Tomography in Ab Interno Glaucoma Surgery
      Purpose : Ab interno glaucoma surgery , such as trabecular aspiration or ab interno trabeculotomy, has been introduced as an alternative, non-filtering procedure to lower intraocular pressure in glaucoma patients. The purpose of the present study was to assess the feasibility of intraoperative spectral domain optical coherence tomography (iOCT) for improving ab interno glaucoma surgery . Materials and Methods : Intraoperative optical coherence tomography was performed to visualize the anterior chamber angle, the aspiration ...
