34例(37只眼)就诊于赫尔辛基大学眼科医院的青光眼患者经透照定位睫状体冷冻术治疗后,均取得了眼压控制或疼痛缓解。随访时间1～43个月(平均9个月)。治疗前眼压为38±14mmHg。术后眼压为27±17mmHg(均值±SD),行1次冷冻者24只眼,行2～5次冷冻者13只眼。51%眼压控制(9～24mmHg)。无虹膜新生血管者对手术反应(62%取得眼压控制)较有虹膜新生血管者(38%取得眼压控制)为佳。继发于慢性色素膜炎者手术反应最佳(6/7眼压控制)。重复冷冻提高了眼压控制率。为止痛而手术的13只眼中,85%达到止痛目的。术后30%视力无改变,54%视力下降。通过透照指示使冷冻头在正确部位进行冷冻。3只眼(8%)发生低眼压(IOP<9mmHg)但无眼球萎缩的临床体征。
Twenty-four eyes (37 eyes) of glaucoma treated at Ophthalmic Hospital of Helsinki University underwent intraocular pressure control or pain relief after percutaneous ciliary body cryosurgery. Follow-up time of 1 to 43 months (mean 9 months). The intraocular pressure before treatment was 38 ± 14 mmHg. Postoperative intraocular pressure was 27 ± 17 mmHg (mean ± SD), 24 eyes were frozen in one operation, and 13 eyes were frozen in 2 to 5 operations. 51% intraocular pressure control (9 ~ 24mmHg). No iris neovascularization of the surgical response (62% achieved intraocular pressure control) compared with iris neovascularization (38% obtained intraocular pressure control) is better. Surgical response secondary to chronic uveitis is best (6/7 IOP control). Repeated freezing increased IOP control. To pain and surgery in 13 eyes, 85% to achieve the purpose of painkillers. After 30% visual acuity was unchanged, 54% vision loss. Pass through the freezing instructions to allow the freezer to freeze at the correct place. Clinical signs of hypotony (IOP <9 mmHg) but no atrophy of the eye occurred in 3 eyes (8%).
