对67例双眼高度近视伴后巩膜葡萄肿患者(134眼)用美国产Ophthasonie A/BⅢ+眼科专用扫描仪进行探测,直接接触法.A超自动测量眼轴长度,B超探测葡萄肿形态、位置及范围,发现葡萄肿有锥形、方形、楔形、弧形四种形态,后巩膜葡萄肿有以下特征:①大部分为锥形;②多位于后极部;③双眼者绝大部分形态、位置相同;④锥形者以位于距视盘颞侧2～5mm范围为多;⑤方形位于后极部者随葡萄肿面积扩大,眼轴逐渐变短;⑥楔形者以横形为主,随眼轴延长而加长.%sixty-seven(134 eyes)of bilateral high myopia with posterior staphyloma cases were examined by the OPHTHASONIC A-sean/B-scan Ⅲ plus made in he United States.Each eye was examined with direct contact manner.Axial length was measured automatically by ultrasound A and the shape,position and scope of staphylomas,were detected by uhrasound B.Four types of staphylomas were found.They are conic,square,wedge and arc shaped.The staphyloma showed the following features:(1)they were conic shaped in most eyes;(2)most staphylomas were situated in the posterior poles;(3)the shape and position were similar in most patients with bilateral staphylomas;(4)the conic shaped staphylomas were commonly situated 2-5mm temporal to the border fo the optic disc;(5)as the square shaped staphylomas enlarged,the axis length of eye shortened gradually;(6)the wedige shaped staphylomas most frequedtly appeared horizontal and were lengthened as the axis length of eye prolonged.
