The condition of the corneal epithelium is a critical determinant of corneal transparency and clear vision. The corneal epithelium serves as a barrier to protect the eye from external insults, with its smooth surface being essential for its optical properties. Disorders of the corneal epithelium include superficial punctate keratopathy, corneal erosion, and persistent epithelial defects (PEDs)....

PURPOSE To demonstrate the use of phase-variance optical coherence tomography (PV-OCT) angiography for detection of pigment epithelial detachment (PED) vascularization in age-related macular degeneration (AMD). PATIENTS AND METHODS Patients with PEDs and exudative AMD were evaluated by the Retina Services at the University of California, Davis, and the University of California, San Francisco....

OBJECTIVE To determine 1) the performing of circumcision by medical specialty, gender, and years of practice; 2) the pattern of anesthetic use for this procedure; and 3) the reasons physicians cite for not using anesthesia. DESIGN A total of 3066 questionnaires were received from a mailing to a representative sampling of physicians stratified by specialty and geographic location. RESULTS Fi...

Objective: To analyze a 7-year natural history of idiopathic multiple retinal pigment epithelium (RPE) detachment based on optical coherence tomography (OCT) images. Methods: Case report. SD-OCT imaging (Topcon 3D OCT-1000). Results: A 55-year-old female presented with three foci of pigment epithelium detachment (PED) in her left eye. Her past ophthalmic and medical history was uneventful. The ...

We demonstrate the use of polyethylene devices (PEDs) for assessing hydrophobic organic compounds (HOCs) in aquatic environments. Like semipermeable membrane devices (SPMDs) and solid-phase microextraction (SPME), PEDs passively accumulate HOCs in proportion to their freely dissolved concentrations. Polyethylene-water partition constants (K(PEW)S) were measured in the laboratory for eight polyc...

OBJECTIVE Classify rhythmic EEG patterns in extremely preterm infants and relate these to brain injury and outcome. METHODS Retrospective analysis of 77 infants born <28 weeks gestational age (GA) who had a 2-channel EEG during the first 72 h after birth. Patterns detected by the BrainZ seizure detection algorithm were categorized: ictal discharges, periodic epileptiform discharges (PEDs) and...

Abstract Positive Energy Districts (PEDs) are potential high-impact climate change mitigation actions towards low carbon or even neutral cities. This implies that the energy performance and greenhouse gas emissions of PEDs need to be assessed. To this end, an accounting methodology, metrics, supporting (accounting) tools, reporting necessary capture full impact PEDs. The European Commission's B...

objectives: there are various developmental screening tools that are different in terms of psychometric characteristics and choosing the best one is challenging for the pediatrician. this research was designed to identify the validity and reliability of parents evaluation of developmental status, a developmental screening questionnaire, in 4-60 months-old children in the city of tehran. methods...
