白内障囊内摘出术中玻璃状体脱出的研讨

本文报告从1986年8月～1987年11月,共做了白内障冷冻囊内摘出术72例(93眼),术中玻璃状体脱出者22眼,占23.76%。并对影响玻璃状体脱出的诸因素如麻醉方法、眼内压、术前(中)用降眼压药物、病人是否合作和术者与助手配合的情况作了分析,发现本组并发症与基础眼压和术者与助配合两个因素较为密切,有显著差异。P 值<0.05.并发现玻璃状体脱出对病者复明增视有极其显著的影响,除裸眼视力低下外,矫正视力≤0.1者占50%,与无玻璃状体脱出组对比 P 值<0.01,有极其显著的差异。

Researches on Vitreous Prolapse During Intracapuslar Cryoextraction

The report is about 72 cases (93eyes) of intracapuslar cryoextraction performed from Aug.1986 to Nov.1987.During the operations,22 cases occurred vitreous prolapse which accounts for 23. 78%.The factors causing vitreous prolapse have been analysed,e.g,anaesthesia method,adminis- trating medicines,intraocular pressure,medicines to reduce intraocular pressure before or during opera- tions,cooperation among doctor,assistant and patient,etc.It is found that of all the above factors two have very close and significant relation,i.e.intraocular pressure and cooperation between opeva- tire doctor and assistant.Their probability is P<0.05.It is also found that vitreous prolapse disturbs the recovery of visual sense and the improvement of eyesight.Correcting defects of vision<0.1 ac- counts for 50% except bared low eyesight,compared with non-vitreous prolapse The comparision of the two groups is P<0.01.It shows that there is remarkable difference between them.
