    2. Retinal Microanatomy in Retinopathy of Prematurity

      Retinal Microanatomy in Retinopathy of Prematurity
      Retinopathy of prematurity (ROP) is a disorder of development of the neural retina and its vasculature that can impact vision in vulnerable preterm neonates for a lifetime. This study tests high-speed optical coherence tomography (OCT) technology compared to conventional color photographs at the bedside of very preterm infants in the intensive care nursery, to characterize previously unseen abnormalities that can predict a need for referral for ROP treatment, or poor ...

    3. Evaluation of the Cirrus HD-OCT Normative Database Probability Codes in an African American Population

      Evaluation of the Cirrus HD-OCT Normative Database Probability Codes in an African American Population
      Objective: Race-adjusted interpretation of data from Cirrus high-definition optical coherence tomography (HD-OCT) devices is not standard practice. The aim of this study is to evaluate differences in peripapillary retinal nerve fiber layer (RNFL) thickness between healthy African Americans and the Cirrus HD-OCT normative database. Design: This is a cross-sectional observational study using control patients recruited from the greater Philadelphia, Pennsylvania area. Subjects: A total of 466 eyes were included in ...

    5. Utility of Ultrasound and Optical Coherence Tomography in Differentiating Between Papilledema and Pseudopapilledema in Children

      Utility of Ultrasound and Optical Coherence Tomography in Differentiating Between Papilledema and Pseudopapilledema in Children
      Background: Differentiating between papilledema and pseudopapilledema in children presenting with mild-to-moderate optic nerve head elevation is challenging. This study sought to determine which B-scan ultrasonography (BSUS) and optical coherence tomography (OCT) features, individually or in combination, are best able to differentiate between papilledema and pseudopapilledema in children. Methods: Children presenting with optic nerve head elevation of unknown etiology were eligible if they underwent BSUS and OCT performed by the same ...

    6. Preterm Infant Stress During Handheld Optical Coherence Tomography vs Binocular Indirect Ophthalmoscopy Examination for Retinopathy of Prematurity

      Preterm Infant Stress During Handheld Optical Coherence Tomography vs Binocular Indirect Ophthalmoscopy Examination for Retinopathy of Prematurity
      Importance: Binocular indirect ophthalmoscopy (BIO) examination for retinopathy of prematurity (ROP) is a well-known cause of repeated preterm infant stress. Objective: To compare stress during investigational optical coherence tomography (OCT) imaging to that during BIO for ROP. Design, setting, and participants: This cross-sectional study examined infants at the bedside in the intensive care nursery. Consecutive preterm infants enrolled in Study of Eye Imaging in Preterm Infants (BabySTEPS) who had any ...

    7. Evaluating the association of clinical factors and optical coherence tomography retinal imaging with axial length and axial length growth among preterm infants

      Evaluating the association of clinical factors and optical coherence tomography retinal imaging with axial length and axial length growth among preterm infants
      Purpose To study the association of clinical factors and optical coherence tomography (OCT) retinal imaging with axial length (AL) and AL growth in preterm infants Methods Among a subgroup of infants from the prospective BabySTEPS study who were screened for retinopathy of prematurity (ROP) and had both AL measured and OCT imaging performed, we analyzed data collected prior to 42 weeks postmenstrual age (PMA) and prior to ROP treatment. Using ...

    8. Comparison of Spectralis and Cirrus optical coherence tomography for the detection of incomplete and complete retinal pigment epithelium and outer retinal atrophy

      Comparison of Spectralis and Cirrus optical coherence tomography for the detection of incomplete and complete retinal pigment epithelium and outer retinal atrophy
      Purpose: To evaluate and compare the detection of incomplete and complete retinal pigment epithelial and outer retinal atrophy (iRORA and cRORA) using Spectralis and Cirrus optical coherence tomography (OCT) devices. Methods: Subjects with late age-related macular degeneration (AMD) were imaged on the same day with Spectralis and Cirrus OCT. Two masked, independent and experienced retina specialist graders evaluated each case for the presence of cRORA and iRORA lesions. Results: A ...

    10. Utility of Spectral-Domain Optical Coherence Tomography in Differentiating Papilledema From Pseudopapilledema: A Prospective Longitudinal Study

      Utility of Spectral-Domain Optical Coherence Tomography in Differentiating Papilledema From Pseudopapilledema: A Prospective Longitudinal Study
      Background: Prospective and longitudinal studies assessing the utility of spectral-domain optical coherence tomography (SD-OCT) to differentiate papilledema from pseudopapilledema are lacking. We studied the sensitivity and specificity of baseline and longitudinal changes in SD-OCT parameters with 3D segmentation software to distinguish between papilledema and pseudopapilledema in a cohort of patients referred for evaluation of undiagnosed optic disc elevation. Methods: Fifty-two adult patients with optic disc elevation were enrolled in a ...

      Objective To report our ability to capture, grade reliably and analyze bedside macular optical coherence tomography (OCT) images from preterm infants and relate OCT findings to biological factors and retinopathy of prematurity (ROP) status at a single time window in the STudy of Eye imaging in Preterm infantS (BabySTEPS). Design Prospective observational study Participants Preterm infants eligible for ROP screening, with parental consent for research and a 361 weeks postmenstrual ...

      Steps Forward in Analyzing Optical Coherence Tomography in Age-Related Macular Degeneration—Capitalizing on the Power of Artificial Intelligence
      Imaging of the retina, originally by stereoscopic fundus photography and later by optical coherence tomography (OCT), has been essential to the diagnosis and monitoring of progression of age-related macular degeneration. Manual grading of color photographs acquired during the Age-Related Eye Disease Study to detect and quantify drusen and pigmentary changes led to a detailed severity scale that stratified 5-year risk of late AMD into 9 categories, with risk estimates ranging ...

      Optic Neuropathy in Charcot–Marie–Tooth Disease
      Background: CharcotMarieTooth disease Type 2A (CMT2A) presents with optic atrophy in a subset of patients, but the prevalence and severity of optic nerve involvement in relation to other CMT subtypes has not been explored. Methods: Patients with genetically confirmed CMT2A (n = 5), CMT1A (n = 9) and CMTX1 (n = 10) underwent high- and low-contrast acuity testing using Sloan letter charts, and circumpapillary retinal nerve fiber layer (RNFL) and macular total retinal ...
