Report Shape of the VEP results for healthy babies and babies with HIE

研究概览

简要总结

The purpose of this research study is to gather more information on how eye injury is related to a baby's future development and see if eye function and brain test results can be used, along with current measures, to better diagnose and treat babies with hypoxic-ischemic encephalopathy (HIE).

Participants will undergo up to two eye exam sessions, involving both Visual Evoked Potential (VEP) and Electroretinogram (ERG) exams.

详细描述

Specific Aims/Study Objectives:

In this proposed longitudinal study, the investigators hypothesize that the early visual function findings will correlate with the neurodevelopmental and neuroimaging outcomes in children who sustain HIE. The investigators will test this hypothesis through the following specific aims:

  • Specific Aim 1 will determine the correlation of the ERG results as a measure of the retinal function obtained at around birth, 3, 9, 18 or 30 months of life and neurodevelopmental-neuroimaging outcomes from birth through 36 months.
  • Specific Aim 2 will determine the correlation of the VEP as a measure of the visual cortical function obtained at around birth, 3, 9, 18 or 30 months of life and neurodevelopmental-neuroimaging outcomes from birth through 36 months.
  • Specific Aim 3 will collect ERG and VEP results from well babies in the Newborn Nursery and compare results to neonates with HIE.
  • Specific Aim 4 will determine if machine learning will predict the clinical outcomes using VEP, ERG, and EEG waveform data, as well as MR imaging files (exploratory)

As health care providers, the investigators' goal is to develop a noninvasive and novel quantitative tool to improve the neurodevelopmental outcome of neonates and to support them in attaining maximum functional potential in childhood and beyond.
