A consecutive series of 38 eyes of 35 glaucoma patients treated with transillumination guided cyclocryotherapy (CCT) either to obtain pain relief or to achieve IOP control was studied at Helsinki University Eye Hospital. Transillumination was used to guide the applications to the correct site. The follow-up range was 1-43 months (mean 9 months). Pretreatment IOP was 39 +/- 13 mm Hg and postoperative 26 +/- 16 mm Hg (mean +/- SD). Twenty-three eyes underwent one and 15 eyes 2-5 procedures. IOP control (IOP 9-23 mm Hg) was achieved in 50%. The response was more favorable in eyes without iris neovascularisation (59% achieved IOP control) than in eyes with neovascular glaucoma (38% achieved IOP control). The best response was achieved in eyes with chronic uveitis (5/7 eyes achieved IOP control). Repeated procedures improved the IOP control rate. Hypotony (IOP < 9 mm Hg) without clinical signs of phthisis occurred in three eyes (8%). Thirteen eyes needed primarily pain relief and 92% achieved it. Postoperatively vision was better in 8%, unchanged in 37% and worse in 55%. Visual acuity was 0.05 or better in nine eyes pretreatment and in eight eyes after treatment.
在赫尔辛基大学眼科医院，对35例青光眼患者的38只眼睛进行了连续系列研究，这些患者接受了透照引导下的睫状体冷凝术（CCT），目的是缓解疼痛或控制眼压。透照用于将治疗应用引导至正确部位。随访时间为1至43个月（平均9个月）。治疗前眼压为39±13 mmHg，术后为26±16 mmHg（平均值±标准差）。23只眼睛接受了1次治疗，15只眼睛接受了2至5次治疗。50%的患者实现了眼压控制（眼压为9至23 mmHg）。无虹膜新生血管的眼睛反应更好（59%实现眼压控制），而新生血管性青光眼患者的眼睛反应较差（38%实现眼压控制）。慢性葡萄膜炎患者的眼睛反应最佳（5/7只眼睛实现眼压控制）。重复治疗提高了眼压控制率。3只眼睛（8%）出现了低眼压（眼压<9 mmHg），且无眼球痨的临床体征。13只眼睛主要需要缓解疼痛，92%的患者实现了疼痛缓解。术后视力改善的占8%，不变的占37%，变差的占55%。治疗前9只眼睛的视力为0.05或更好，治疗后8只眼睛的视力为0.05或更好。
