Optical clearing with tartrazine enables deep transscleral imaging with optical coherence tomography.

Significance: Imaging deep structures with optical coherence tomography (OCT) is difficult in highly scattering biological tissue, such as the sclera. There is a need to visualize the suprachoroidal space and choroid through the sclera to study suprachoroidal drug delivery.

Aim: We aim to develop optical methods to image through the highly scattering sclera with a custom-built OCT system to visualize the suprachoroidal space and drug delivery within.

Optical Clearing with Tartrazine Enables Deep Transscleral Imaging with Optical Coherence Tomography.

Suprachoroidal injections are a relatively new method of drug delivery to treat retinal disease. At present, it is difficult to visualize the distribution of injection-delivered product beneath the sclera into the suprachoroidal space. Imaging the suprachoroidal space with OCT is hindered by scattering of light from densely packed collagen fibers of the sclera, limiting depth penetration of the OCT light.

Robotic Optical Coherence Tomography of Human Subjects with Posture-Invariant Head and Eye Alignment in Six Degrees of Freedom.

Ophthalmic optical coherence tomography (OCT) has achieved remarkable clinical success but remains sequestered in ophthalmology specialty offices. Recently introduced robotic OCT systems seek to expand patient access but fall short of their full potential due to significant imaging workspace and motion planning restrictions. Here, we present a next-generation robotic OCT system capable of imaging in any head orientation or posture that is mechanically reachable.

Vocal Fold Movement and Silent Aspiration After Congenital Heart Surgery.

Objectives/hypothesis: Infants who undergo congenital heart surgery are at risk of developing vocal fold motion impairment (VFMI) and swallowing difficulties. This study aims to describe the dysphagia in this population and explore the associations between surgical complexity and vocal fold mobility with dysphagia and airway protection.

Study Design: Retrospective chart review.

Videofluoroscopic Swallow Study Findings and Correlations in Infancy of Children with Cerebral Palsy.

Objectives: Cerebral palsy (CP) in infants can affect global motor function and lead to swallowing difficulties. This study aims to characterize oral and pharyngeal swallowing dynamics in infancy of patients later diagnosed with CP and to determine if swallow study performance in early infancy is associated with later CP severity and characteristics.

Methods: This is a retrospective chart review of infants who underwent videofluoroscopic swallow studies (VFSS) between 6/2008 and 10/2018 at a tertiary children's hospital, and were later diagnosed with CP.

Quantification of Mandibular Morphology in Pierre Robin Sequence to Optimize Mandibular Distraction Osteogenesis.

Background: Mandibular distraction osteogenesis (MDO) is the primary surgical intervention to treat airway obstruction in Pierre Robin sequence (PRS). Current morphologic studies of PRS mandibles do not translate into providing airway management decisions. We compare mandibles of infants with nonsyndromic PRS to controls characterizing morphological variances relevant to distraction.

Airway protection & patterns of dysphagia in infants with down syndrome: Videofluoroscopic swallow study findings & correlations.

Introduction: Down syndrome is a genetic condition that affects 1:737 births. Along with cardiac, otolaryngologic, and developmental anomalies, infants with Down syndrome can have swallowing difficulties resulting in respiratory infections. This study aims to characterize the airway protection and dysphagia seen in infants with Down syndrome.
