In surgery for retinal detachment, such as shortening of the eyeball, volume reducing, and indentating operations, knowledge of the volume of the subretinal fluid is important. A method based on ultrasonography was developed to measure the volume of subretinal fluid preoperatively. After establishing a topography of the fundus, the height of retinal detachment can be measured by ultrasonography at 49 defined points. The diameter of the eyeball is measured at 12 different points. From the height of retinal detachment and the diameter of the eyeball it is possible to calculate the subretinal space, which is divided into 60 segments. The total volume of subretinal fluid is calculated by adding the volumes of these 60 segments. The calculus is programmed on a computer.
在视网膜脱离手术中，如眼球缩短、容积减小和压陷手术，了解视网膜下液的容积很重要。已开发出一种基于超声检查的方法来术前测量视网膜下液的容积。在建立眼底地形图后，可通过超声检查在49个定义点测量视网膜脱离的高度。在12个不同点测量眼球直径。根据视网膜脱离的高度和眼球直径，可以计算出视网膜下间隙，该间隙被分为60个节段。通过将这60个节段的容积相加来计算视网膜下液的总体积。该计算过程在计算机上编程实现。
