严重眼外伤Ⅰ期术后低眼压解决方案及预后分析

目的:探讨严重眼外伤I期术中或术后应用全氟丙烷(C3F8)气体对眼内压及其预后的影响。方法:选择严重眼外伤26例(26眼),I期术中或术后注入纯全氟丙烷气体,观察眼压并于II期术中观察气体作用效果及预后评价。结果:注气术后眼压得到改善23眼,18眼角膜水肿混浊经气体充填后恢复透明15眼,II期术中在气体作用下视网膜在复位状态共21眼。术后随诊3～12mo,视力提高22眼,视力不变3眼,视力下降1眼。结论:严重眼外伤I期术中或术后应用全氟丙烷气体能有效提升眼内压同时取得良好的预后。

Solution and prognostic analysis of hypotony after primary operation of severe ocular trauma

· AIM: To explore the effects of C3F8 tamponade on hypotony on or after primary operation and the prognosis of severe ocular trauma.· METHODS: Twenty-six cases (26 eyes) of severe ocular trauma were treated with pure C3F8 tamponade on or after primary operation. IOP was observed, and the curative effect of C3F8 tamponade was observed on secondary operation with prognosis evaluated.· RESULTS: Hypotony improved in 23 eyes postoperatively,in which 18 eyes with edematous and cloudy cornea, 15 eyes had clear cornea after gas tamponade. Retina was reattached under the gas action in 21 eyes during the secondary operation. Visual acuity improved in 22 eyes, remained unchanged in 3 eyes and decreased in 1 eye during the follow-up of 3-12months.· CONCLUSION: Application of pure C3F8 tamponade on or after primary operation can effectively improve hypotony after severe ocular trauma and benefit a better prognosis.
