Non-Invasive Pressure Monitor for Neonates & Infants at Risk of Developing Hydrocephalus

October 3, 2025 updated by: Jignesh Tailor, Indiana University

The goal of this clinical trial is to test a modified smart soft contact lens in neonates and infants at risk of developing hydrocephalus. The main questions it aims to answer are:

  • Can the device distinguish between intracranial pressure variations in neonates and infants diagnosed with hydrocephalus and those without
  • Can the device compare pressure dynamics between pre- and post-operative periods in neonates and infants who undergo surgical treatments Participants will undergo standard of care evaluations for hydrocephalus (anterior fontanelle assessment and head circumference measurement) and wear the device during standard of care evaluation; pre- and post- ventricular reservoir taps, as applicable; and/or pre- and post-operatively, as applicable.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
