PURPOSE We compared photoreceptor development from spectral domain optical coherence tomography (SD-OCT) imaging in very preterm infants (VPT, <32 weeks gestational age) with those of term infants. METHODS The microanatomy of foveal SD-OCT images obtained at the bedside at 37 to 42 weeks term equivalent postmenstrual age (TEA) was reviewed with(More)
We present a methodology for extracting the vascular network in the human retina using Dijkstra's shortest-path algorithm. Our method preserves vessel thickness, requires no manual intervention, and follows vessel branching naturally and efficiently. To test our method, we constructed a retinal video indirect ophthalmoscopy (VIO) image database from(More)
Horner syndrome can be caused by a variety of etiologies that interrupt the sympathetic innervation of the eye, including but not limited to central mass lesions. Recently, it has been debated whether neuroimaging has a place in the diagnostic algorithm of isolated pediatric Horner syndrome given the low incidence of neuroblastoma. We present a case of a(More)
PURPOSE To report the efficacy of sub-Tenon triamcinolone acetonide (TA) injections for chronic blepharokeratoconjunctivitis (BKC) in 2 patients who were intolerant to topical therapies. METHODS In this retrospective observational case series, the records of 2 patients with chronic BKC who received sub-Tenon TA injections were reviewed. RESULTS Both(More)
BACKGROUND ROPtool is a computer program that is used to measure retinal vascular tortuosity and width. Our aim was to determine the best method for combining ROPtool's tortuosity and width values into an overall measure of plus disease. METHODS ROPtool was used to measure vessel tortuosity and width in 184 quadrants of 46 RetCam images of premature(More)
Indirect ophthalmoscopy (IO) is the standard of care for evaluation of the neonatal retina. When recorded on video from a head-mounted camera, IO images have low quality and narrow Field of View (FOV). We present an image fusion methodology for converting a video IO recording into a single, high quality, wide-FOV mosaic that seamlessly blends the best(More)
PURPOSE To report retinal findings for healthy newborn infants imaged with handheld spectral-domain optical coherence tomography (SD OCT). DESIGN Prospective, observational case series. METHODS Thirty-nine full-term newborn infants underwent dilated retinal examinations by indirect ophthalmoscopy and retinal imaging by handheld SD OCT, without sedation,(More)
PURPOSE To determine whether choroidal imaging is feasible in preterm and term infants using an 840-nm portable spectral domain optical coherence tomography (SD-OCT) system without the use of enhanced-depth imaging techniques and to assess choroidal development by comparing choroidal thickness of preterm infants, term infants, and adults. METHODS SD-OCT(More)
PURPOSE To characterize optic nerve head (ONH) morphology and parameters, including vertical disk diameter, vertical cup diameter, and vertical cup/disk ratio in healthy, full-term newborns using a handheld spectral domain optical coherence tomography (SD-OCT) device. METHODS In this prospective observational case series, healthy white, black, and(More)
BACKGROUND AND OBJECTIVE To explore characteristics associated with cystoid macular edema (CME) in neonates screened for retinopathy of prematurity (ROP). PATIENTS AND METHODS In this institutional review board-approved, prospective, observational study, premature neonates underwent imaging with handheld spectral-domain optical coherence tomography.
