## New Study highlights reliable Gaze Measurements with neos®

 Feb 13, 2025

A recent study by Ana Coito PhD, Avantika Naidu PhD, Julian Lehmann MS, Bruno Hauser MS, Dominik Brügger PhD, and Mathias Abegg MD PhD evaluated the test-retest reliability of gaze precision of neos®  in all 9 cardinal directions. The researchers used a custom-made robotic pair of eyes to simulate human eye movements in ideal conditions and without the inherent biological variability. 

Key Findings of the Study: 

1. **High Test-Retest Reliability:** neos® demonstrated strong consistency in gaze precision measurements, with an Intraclass Correlation Coefficient (ICC) greater than 0.99 and a Standard Error of Measurement (SEM) of 0.04. This indicates neos® has the ability to reliably measure gaze direction movements of each individual eye in all 9 gaze directions.

1. **Consistent Measurements Across All Directions**: The system maintained stable gaze precision in all nine cardinal gaze directions, ensuring  reliable measurement of each eye within the central 20 degrees of vision.

1. **Stable Performance Under Noise Conditions**: Even when subjected to simulated disturbances, neos® delivered consistent results, indicating its robustness for practical clinical use.

The results demonstrate that neos® provides reliable, consistent and robust measurements of individual eye movements, supporting its use in a vast array of clinical applications to objectively measure functional eye movements. neos® has the potential to become an invaluable tool to aid in screening, diagnosis, and monitoring of oculomotor conditions that are highly relevant in ophthalmology and neurology.
