【摘要】 为研究后房型人工晶体植入术后前房角及眼前节改变，对术后不同时期的１３０只眼及白内障囊外摘除术后２０只眼进行前房角镜、散瞳前后裂隙灯以及视力、眼压及眼底等项检查。结果发现，５０．８％发生襻性周边前粘连（ｌｅｎｓｈａｐｔｉｃｐｅｒｉｐｈｅｒａｌａｎｔｅｒｉｏｒｓｙｎｅｃｈｉａ，ＰＡＳ）。襻性ＰＡＳ易于辨认，为宽基底的周边虹膜向前隆起，并与房角前壁相粘连，其范围约为０．５～１个钟点，个别为１．５～２个钟点。术后各时间组间襻性ＰＡＳ发生率的差别无显著性（Ｐ＞０．０５）。睫状沟固定者中５５．９％有襻性ＰＡＳ，囊袋内固定者襻性ＰＡＳ占４２．３％（Ｐ＞０．０５）。人工晶体呈水平位者襻性ＰＡＳ（６２．７％）较垂直位者（４１．４％）多（Ｐ＜０．０５）。人工晶体组中瞳孔不圆及房角色素沉着者较羹外摘除组多。认为人工晶体植入术后应定期作前房角镜检查，对术前患青光眼或可疑青光眼者尤为重要。更多还原

【Abstract】 To study the changes of the anterior chamber angle after intraocular lens implantation,111 patients(130 eyes)with posterior chamber intraocular lens implantation at different post- operative perieds were exam ined by gonioscopy. Peripheral anterior synechia overlying the position of the lens haptic (lens haptic PAS)was observed in up to 50.8%of eyes implanted with haptics vaulted anteriorly bv 10°。The lens haptic PAS is easy to be identified,it is a broad based forward displacement of the pe-ripheral iris adhesive to the anterior wall of the anterior chamber angle。The size of the PAS was of half to one o ’clock position and occasionally it was of one and a half to two o’clock position,The differences between the rates of occurrence of lens haptic PAS were not significant at different post- operative peri-ods(P>0. 05 ).55.9%of the sulcus fixated and 42.3%of the capsular fixated eyes had lens haptic PAS(P> 0. 05 ).There were more lens haptic PAS in eyes with horizontally orientated lens haptics(62.7%)than with lens haptics at vertical position (41.4%, P<0. 05).Regular gonioscopy for poste-rior chamber lens implantation was recommended.更多还原
