• Conditions: Hydrocephalus patients undergoing ventriculo-peritoneal shunt surgery

• Registration Number: CTRI/2016/11/007438
• Lead Sponsor: JIPMER postgraduate research monitoring committee

Brief Summary

This study is an observational study comparing optic nerve sheath diameter measured by ultrasonography and computed tomography in 60 hydrocephalus patients undergoing ventriculo-peritoneal shunt surgery.

The primary outcome measure will be the optic nerve sheath diameter measurement preoperatively and 12 hours after the surgery by both ultrasonography and computed tomography. The correlation among the

measurement by ultrasonogphy and computed tomography will be measured. The secondary outcome will be to  identify the association of the ONSD with clinical factors among the patients undergoing VPS surgery after 12 hours.
