摘要

睫狀體冷凍治療一般用於末期青光眼的治療。本篇以回溯性方法探討其臨床上的療效。本篇乃收集過去七年中在馬偕醫院接受睫狀體冷凍治療的病例，共33位病患的33隻眼睛。其中23例為新生血管性青光眼，2例為無水晶體性青光眼，1例為人工水晶體性青光眼，4例為隅角閉鎖性青光眼，1例為末期隅角閉放性青光眼，2例為晶體肌位續中性青光眼。追蹤期間從3個月到81個月，平均19.8個月。街前眼壓平均48.9±12.0mmHg，街視眼壓平均31.5±17.6mmHg，平均下降17.4mmHg。眼壓控制良好者（即眼壓低鈴21mmHg）佔30.6%。疼痛顯著改善者佔75.0%。角膜水腫改善者佔95.5%。虹彩新生血管消退者佔70.4%。結果顯示睫狀體冷凍治療可有效地改善眼球疼痛，角膜水腫及虹彩新生血管，但對眼壓的控制則不理想。此外發生眼球萎縮者有2例。

Cyclocryotherapy is one of the treatment modalities in end stage glaucoma. We evaluated its clinical efficacy retrospectively. This study collected 33 eyes of 33 patients who received cycloctyottierapy in the past 7 years at Mackay Memorial Hospital. Twenty-three eyes were enrolled into the neovascular glaucoma group, 2 eyes into the aphakic glaucoma group, 1 eye into the pseudophakic glaucoma group, 4 eyes into the angle closure glaucoma group, 1 eye into the end stage open angle glaucoma group, and 2 eyes into the lens-induced glaucoma group. The follow-up period ranged front 3 months to 81 months (average 19.8 months). The pre-operative intraocular pressure (IOP) averaged 48.9±12.0mmHg. The results showed the postoperative IOP averaged 31.5±17.6mmHg, and the average decrease in IOP was 17.4mmHg. Well-controlled IOP (i.e. IOP＜21mmHg was 30.6%. Pain relief was 75.0%. Improvement of corneal edema was 95.5%. Regression of rubeosis iridis seas 70.4%. In conclusion, cyctociyottterapy was indeed effective in pain relief, insprovensent of corneal edema and regression of rubeosis iridis. But the control of IOP was unsatisfactory. Furthermore, 2 cases of phthisis bulbi were noted.
