      Near‐infrared imaging and optical coherence tomography for intraoperative visualization of tumors
      Surgical excision is the foundation of treatment for early‐stage solid tumors in man and companion animals. Complete excision with appropriate margins of surrounding tumor‐free tissue is crucial to survival. Intraoperative imaging allows real‐time visualization of tumors, assessment of surgical margins, and, potentially, lymph nodes and satellite metastatic lesions, allowing surgeons to perform complete tumor resections while sparing surrounding vital anatomic structures. This Review will focus on the ...

      Baseline Spectral Domain Optical Coherence Tomography Characteristics of Age-Related Macular Degeneration
      Purpose: To describe spectral domain optical coherence tomography (SD-OCT) findings in an Amish cohort to assess SD-OCT markers for early age-related macular degeneration (AMD). Methods: The authors performed a family-based prospective cohort study of 1,146 elderly Amish subjects (age range 5099 years) (2,292 eyes) who had a family history of at least 1 individual with AMD. All subjects underwent complete ophthalmic examinations, SD-OCT using both Cirrus and Spectralis ...

      Optical coherence tomography identifies outer retina thinning in frontotemporal degeneration
      Objective: Whereas Alzheimer disease (AD) is associated with inner retina thinning visualized by spectral-domain optical coherence tomography (SD-OCT), we sought to determine if the retina has a distinguishing biomarker for frontotemporal degeneration (FTD). Methods: Using a cross-sectional design, we examined retinal structure in 38 consecutively enrolled patients with FTD and 44 controls using a standard SD-OCT protocol. Retinal layers were segmented with the Iowa Reference Algorithm. Subgroups of highly predictive ...

      Optical coherence tomography and visual evoked potentials in pediatric MS
      Objective: To determine the relative ability of optical coherence tomography (OCT) and pattern-reversal visual evoked potentials (pVEPs) to detect visual pathway involvement in pediatric-onset MS. Methods: Pediatric-onset MS participants (onset 18 years) and healthy controls (HCs) underwent OCT (Cirrus HD-OCT) and pVEPs. Retinal nerve fiber layer (RNFL), ganglion cell layer to inner plexiform layer (GCL-IPL), and P100 pVEP latency were measured. Generalized estimating equation models were used to compare the ...

      Optical Coherence Tomography Angiography of a Central Retinal Artery Occlusion Before and After Anterior Chamber Paracentesis
      A 74-year-old man presented 6 hours after sudden painless vision loss in the left eye. He had finger counting vision, normal intraocular pressure, and an afferent pupillary defect. Diagnosis of central retinal artery occlusion was made. Optical coherence tomography angiography performed before (Fig 1 A , C ) and immediately after (Fig 1 B , D ) anterior chamber paracentesis showed dramatic improvement in macular perfusion. Vision was 20/70 at the 1-month visit ...

      Evaluation of Optical Coherence Tomography to Detect Elevated Intracranial Pressure in Children
      Importance Detecting elevated intracranial pressure in children with subacute conditions, such as craniosynostosis or tumor, may enable timely intervention and prevent neurocognitive impairment, but conventional techniques are invasive and often equivocal. Elevated intracranial pressure leads to structural changes in the peripapillary retina. Spectral-domain (SD) optical coherence tomography (OCT) can noninvasively quantify retinal layers to a micron-level resolution. Objective To evaluate whether retinal measurements from OCT can serve as an effective ...

      Imaging the adult zebrafish cone mosaic using optical coherence tomography
      Zebrafish ( Danio rerio ) provide many advantages as a model organism for studying ocular disease and development, and there is great interest in the ability to non-invasively assess their photoreceptor mosaic. Despite recent applications of scanning light ophthalmoscopy, fundus photography, and gonioscopy to in vivo imaging of the adult zebrafish eye, current techniques either lack accurate scaling information (limiting quantitative analyses) or require euthanizing the fish (precluding longitudinal analyses). Here we ...

      Outer Retinal Changes Including the Ellipsoid Zone Band in Usher Syndrome 1B due to MYO7A Mutations
      Purpose : To study transition zones from normal to abnormal retina in Usher syndrome IB (USH1B) caused by myosin 7A ( MYO7A ) mutations. Methods : Optical coherence tomography (OCT) scattering layers in outer retina were segmented in patients ( n = 16, ages 242; eight patients had serial data, average interval 4.5 years) to quantify outer nuclear layer (ONL) and outer segments (OS) as well as the locus of EZ (ellipsoid zone) edge and ...

      The fundus photo has met its match: optical coherence tomography and adaptive optics ophthalmoscopy are here to stay
      Purpose Over the past 25 years, optical coherence tomography (OCT) and adaptive optics (AO) ophthalmoscopy have revolutionised our ability to non-invasively observe the living retina. The purpose of this review is to highlight the techniques and human clinical applications of recent advances in OCT and adaptive optics scanning laser/light ophthalmoscopy (AOSLO) ophthalmic imaging. Recent findings Optical coherence tomography retinal and optic nerve head (ONH) imaging technology allows high resolution ...
