Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are critically ill patients in intensive care units who have been prescribed regular pupillary assessments by their attending physicians.

Probably not a fit

Patients who are outpatients or those without orders for regular pupillary assessments will not benefit from this study.

What this trial studies

This observational study aims to gather extensive data on pupillometer readings to establish normative values for pupillary assessments in critically ill patients. By collecting data from patients in intensive care units who undergo regular pupillary evaluations, the study seeks to enhance understanding of clinically relevant pupil metrics such as size, reactivity, and the neurological pupil index. The data collected will serve as a foundation for future research and improve the interpretation of pupillary assessments in critical care settings.

Why it matters

Potential benefit: If successful, this study could provide critical insights into normal pupillary responses, aiding in the assessment and management of neurological conditions in critically ill patients.

How similar studies have gone: While this approach is focused on establishing normative data, similar studies in pupillometry have shown promise in enhancing clinical assessments, suggesting potential for success.
