To evaluate the use of 3-dimensional ultrasound C-scan imaging for optic nerve diameter measurements.
Prospective observational case series.
Thirty-eight normal eyes of 32 healthy adults.
Coronal C-scans of 38 normal optic nerves were imaged 3 mm behind the globe.
Optic nerve sheath diameter (ONSD) and optic nerve diameter (OND).
Mean ONSD was 4.8 mm (range: 3.9-5.9; SD 0.6), whereas mean optic OND was 1.9 mm (range: 1.8-2.1; SD 0.1). Mean ONSDs were 4.9 mm (male), 4.5 mm (female), 5.0 mm (subjects younger than 50 years), and 4.6 mm (subjects 50 and older).
Coronal C-scans generated from 3-dimensional ultrasound can be used to measure the optic nerve diameters in adult eyes.
评估三维超声C扫描成像在测量视神经直径中的应用。
前瞻性观察病例系列。
32名健康成年人的38只正常眼睛。
在眼球后方3毫米处对视神经进行冠状面C扫描成像。
视神经鞘直径(ONSD)和视神经直径(OND)。
平均ONSD为4.8毫米(范围:3.9 - 5.9;标准差0.6),而平均OND为1.9毫米(范围:1.8 - 2.1;标准差0.1)。男性的平均ONSD为4.9毫米,女性为4.5毫米,年龄小于50岁的受试者为5.0毫米,50岁及以上的受试者为4.6毫米。
三维超声生成的冠状面C扫描可用于测量成人眼睛的视神经直径。
