Ultrasonography is a useful procedure to evaluate volumetric changes in the eye before and after retinal detachment surgery. We found myopic eyes to be variable in shape, most of them ovoidal, and some of them nearly spherical. Given a similar anteroposterior diameter, a spherical eye will have a larger volume than an ovoidal one, and a circling operation will produce a greater reduction than the same procedure in an ovoidal eye. Ultrasonography has been used also to measure the indentation produced by retinal surgery and to follow up its variations through the years.
超声检查是评估视网膜脱离手术前后眼球容积变化的一种有用方法。我们发现近视眼球形状各异，大多数呈椭圆形，有些近乎球形。在前后径相似的情况下，球形眼球的容积比椭圆形眼球大，同样的环扎手术在球形眼球上产生的容积减少量比在椭圆形眼球上更大。超声检查还被用于测量视网膜手术造成的压陷，并多年来跟踪其变化情况。
