感谢 Banboobeyond, 翻译得非常精准,几近出版级。
我解释一下B的最后一句:
When studying a total detachment, it is important to look for a wedge of attached retina near 12 o'clock. The presence of a wedge of attached retina converts the problem of searching for the break in three clock hours (1½ clock hours to either side of 12 o'clock) of suspect retina in a total retinal detachment to one of searching 1½ clock hours in a superolateral or nasal detachment.
在研判一个貌似全网脱时,要注意观察是不是真正的全网脱。如果在上方12点附近有一个楔形的附着区域,则说明这不是真正的全网脱,而是属于A的情况,这时寻找裂孔的方向就要从12点右左各1.5个钟点(全网脱的规律)转移到脱离较高的一侧上缘以下1.5个钟点。
