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。
Objective: To investigate the effect of perfluoropropane (C3F8) gas on intraocular pressure (IOP) and its prognosis during intraoperative or postoperative period of severe ocular trauma. Methods: 26 cases (26 eyes) of severe ocular trauma were selected. Intraoperative or postoperative pure perfluoropropane gas was injected intraoperatively or intraocularly. The intraocular pressure (IOP) was observed and the effect of gas and the prognosis evaluation were observed during the second phase. Results: The intraocular pressure (IOP) was improved in 23 eyes after gas injection. The edema and opacity in 18 eyes recovered 15 eyes after filling with gas. In the second stage, there were 21 eyes under the action of gas in the reset state. Postoperative follow-up 3 ~ 12mo, 22 eyes improved vision unchanged 3 eyes, vision decreased 1 eye. CONCLUSIONS: Intraoperative or postoperative application of perfluoropropane gas in stage I of severe ocular trauma can effectively improve intraocular pressure and achieve good prognosis.
