OPTIC NERVE SHEATH DIAMETER

This study tested a special injection made from the patient's own blood (plasma-rich fibrin) to treat severe headaches that can happen after a spinal tap or epidural. Sixty adults with this type of headache received the injection through a thin tube placed near the spine. The goa…

This study looked at how two common anesthetics, desflurane and propofol, affect pressure inside the eye during laparoscopic gallbladder removal. Researchers measured the optic nerve sheath diameter in 146 adults aged 18-60. The goal was to see which anesthetic might be safer for…

This study looked at how different levels of pressure from a breathing machine (called PEEP) affect the optic nerve sheath diameter, which is a way to check pressure inside the skull. Researchers studied 105 adults having spine surgery while lying on their stomach. They measured …

This study looked at 40 adults having open-heart surgery to see if ultrasound measurements of the optic nerve sheath (the lining around the eye nerve) can detect changes in brain pressure during heart-lung bypass. Researchers measured the nerve sheath at several points during sur…

This study looked at 34 adults having gallbladder surgery to see if a specific lung ventilation setting (called PEEP) changes the size of the optic nerve sheath, which can indicate brain pressure. Researchers measured the nerve with ultrasound at three points during surgery. The …

This study looked at whether ultrasound can measure changes in the optic nerve sheath (the lining around the eye nerve) during liposuction surgery. The goal was to see if different body positions during surgery affect brain pressure. 55 adults having liposuction took part. The re…

This study looked at whether a simple eye ultrasound can detect changes in brain pressure during laparoscopic (keyhole) surgery. 55 adults having laparoscopic surgery had their optic nerve sheath diameter measured with ultrasound during the procedure. The goal was to see if this …

This study looked at 80 adults having open gynecological surgery to see if different amounts of anesthesia gas change the thickness of the nerve at the back of the eye. Researchers measured the nerve with ultrasound before and during surgery at several time points. The goal was t…

This study looked at 63 women having laparoscopic hysterectomy to see if two different anesthetics (sevoflurane and desflurane) affect pressure inside the head differently. The researchers measured the optic nerve sheath diameter using ultrasound as a non-invasive way to check br…

This study examined 309 people with a type of heart failure called HFpEF to understand why some develop atrial fibrillation (AF), an irregular heartbeat. Researchers found that higher pressure in the veins and a wider optic nerve sheath (a sign of increased brain pressure) were l…
