Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients scheduled for ocular manipulation and strabismus surgery.
✕Probably not a fit
Patients with anophthalmia will not benefit from this study.

What this trial studies
This observational study focuses on patients undergoing strabismus surgery, where vital signs and anesthetic variables, particularly heart rate, will be monitored. The study aims to observe the oculocardiac reflex (OCR) by applying uniform tension on extra ocular muscles during the procedure. Data collected will include demographic information and various peri-operative variables to assess the impact of ocular manipulation on heart rate. The study seeks to enhance understanding of the physiological responses during eye surgeries.
Why it matters
Potential benefit: If successful, this study could improve patient safety and outcomes during strabismus surgery by better understanding heart rate responses.
How similar studies have gone: While the specific approach may be novel, studies on the oculocardiac reflex have been conducted, indicating potential for valuable insights.
