Abstract

To identify imaging characteristics of mouse persistent hyperplastic primary vitreous (PHPV) by Spectralis Optical Coherence Tomography (OCT), as well as to assess and compare the sensitivity and precision of OCT with color photography (CP) and Fundus Fluorescein Angiography (FFA) imaging in detecting mouse PHPV. Notch4-/- C57BL/6J mice (224 eyes) aged from 3 months to 7 months were examined in this study. CP, FFA and OCT imaging were utilized to examine vitreous cavity and retina of mouse eyes. Horizontal and radial OCT scan volume was centered on the optic nerve head. Hematoxylin and eosin (H&E) staining was performed to validate PHPV. For color photography and FFA imaging, retrolental irregular fibrovascular membrane-like tissues were found in 33 eyes with/without blood vessels in vitreous cavity. Among them, 31 eyes were visualized with lateral and oblique linear hyperreflective opacities in vitreous cavity using Spectralis OCT. Position of PHPV in posterior segment of eyes was also measured via OCT. Mouse PHPV was validated by H&E staining. Typical hyperreflective opacities in vitreous cavity were detected in PHPV mouse using Spectralis OCT. Spectralis OCT imaging can effectively detect mouse PHPV as color photography and ...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
