Abstract

PURPOSE

To retrospectively evaluate the results of cyclophotocoagulation (CPC) with the transscleral contact red 670-nm diode laser in treating glaucoma.

METHODS

Cyclophotocoagulation was performed in 60 eyes of 60 patients with a mean age of 74 +/- 11 years (range 49-90 years). The treatment was delivered via a fibre-optic probe. The power per application was 430 mW. Exposure time was 10 seconds.

RESULTS

The mean overall follow-up time after the initial CPC was 26 +/- 20 months (range 3-75 months). Preoperative intraocular pressure (IOP) was 27 +/- 11 mmHg (n = 60). After one or more CPC treatments, mean IOP decreased to 20 +/- 7 mmHg (n = 51) at 1 month, 19 +/- 5 mmHg (n = 45) at 3 months, 18 +/- 5 mmHg (n = 29) at 6 months, 19 +/- 7 mmHg (n = 22) at 1 year, 18 +/- 7 mmHg (n = 16) at 2 years, 14 +/- 4 mmHg (n = 8) at 3 years, and 18 +/- 6 mmHg (n = 60) at the last follow-up. An IOP of 8-21 mmHg or a > 30% decrease in IOP was obtained in 33 of 41 eyes (80%) with baseline IOP > 21 mmHg at the last follow-up. Hypotonia (IOP < 8 mmHg) did not develop in any of the eyes studied.

CONCLUSIONS

Cyclophotocoagulation with the red 670-nm diode laser is an effective and well tolerated means of treating glaucoma.

摘要

目的

回顾性评估经巩膜接触式670纳米二极管激光睫状体光凝术（CPC）治疗青光眼的效果。

方法

对60例患者的60只眼睛进行睫状体光凝术，患者平均年龄74±11岁（范围49 - 90岁）。通过光纤探头进行治疗。每次应用的功率为430毫瓦。暴露时间为10秒。

结果

首次CPC术后的平均总随访时间为26±20个月（范围3 - 75个月）。术前眼压（IOP）为27±11毫米汞柱（n = 60）。经过一次或多次CPC治疗后，1个月时平均IOP降至20±7毫米汞柱（n = 51），3个月时为19±5毫米汞柱（n = 45），6个月时为18±5毫米汞柱（n = 29），1年时为19±7毫米汞柱（n = 22），2年时为18±7毫米汞柱（n = 16），3年时为14±4毫米汞柱（n = 8），最后一次随访时为18±6毫米汞柱（n = 60）。在最后一次随访时，41只基线IOP>21毫米汞柱的眼睛中，有33只（80%）眼压达到8 - 21毫米汞柱或眼压降低>30%。在所研究的任何一只眼睛中均未发生低眼压（IOP<8毫米汞柱）。
