Assessing eye parameters in patients with sleep apnea

Ocular Parameters Assessment With a Deep Neural Network in Patients With Sleep Apnea

Observational Democritus University of Thrace · NCT05911737

This study is testing how sleep apnea affects eye movements and drowsiness in adults by comparing those with the condition to those without.

What this trial studies

This observational study aims to evaluate ocular parameters related to drowsiness in patients diagnosed with Obstructive Sleep Apnea Syndrome. It will involve 100 participants aged 18-70, who will be divided into two groups: those with sleep apnea and those without. Participants will watch a 10-minute video in a foreign language while their eye movements are recorded and analyzed using a Raspberry Pi camera system. The study will utilize both objective imaging techniques and subjective questionnaires to assess concentration and drowsiness levels.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 with a diagnosis of obstructive sleep apnea and a minimum distance uncorrected visual acuity of 5/10.

Not a fit: Patients with significant visual impairment (dUVA < 5/10), neurological or psychiatric conditions, or those unable to read may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the ocular effects of sleep apnea, potentially leading to better management strategies for affected patients.

How similar studies have performed: While there may be limited studies directly assessing ocular parameters in sleep apnea, the approach of combining objective and subjective assessments is innovative and not widely tested.
