青光眼睫状体冷冻治疗体会

冷冻睫状体可导致眼压下降早在1950年已由Biett发现,对青光眼病人于睫状体部行中等冷冻后立即引起水肿和血管充血,使上皮破裂而致睫状体血流下降,房水生成减少,从而使眼压降低。由于技术原因,直到60年代中期才开始广泛应用于临床。我们自1986年以来,选择15例17眼不适合手术及药物治疗无效的青光眼     

睫状体冷冻术治疗绝对期青光眼

自Bietti于1950年报告青光眼的冷冻疗法后,60年代开始逐步应用于各种类型的青光眼。我院1986～1991年对9例绝对期青光眼采用睫状体冷冻术治疗,取得较好的效果,报告如下:

全周睫状体冷冻术临床观察

目的探讨全周睫状体冷冻术治疗绝对期青光眼的疗效。方法用全周睫状体冷冻术治疗绝对期青光眼２８眼,结果术后一月内降眼压效果不突出,但一月后即可降至正常范围。同时发现以－６０℃、６０秒,全周睫状体冷冻,最长随访三年,无一例出现并发症及副作用,结论全周睫状体冷冻术用于治疗绝对期青光眼是安全、可靠、合适的。     

Cyclocryotherapy in the treatment of advanced glaucoma

Cyclocryotherapy in the treatment of aphakic open-angle glaucoma (AO), aphakic angle-closure glaucoma (ACL), and neovascular glaucoma (NVG) was evaluated in 96 eyes of 96 patients. All patients had follow-up of greater than 12 months, with a mean of 29.0 +/- 2.1 months (+/- SEM). Intraocular pressure (IOP) was lowered to less than 21 mmHg in 76% of eyes with AO, 68% of eyes with ACL, and 55% of eyes with NVG. Patients with NVG lost vision more frequently (70%) than patients with AO (41%) or ACL (41%). Patients with NVG had a higher incidence of loss of light perception and phthisis bulbi than patients with ACL (P less than 0.015). In patients having visual field examinations (76/96), glaucomatous field loss was arrested in 71% of patients with AO and 65% of patients with ACL, compared to 29% of patients with NVG (P less than 0.025). There was a significant correlation between postoperative IOP less than 21 mmHg and preservation of visual field. Patients receiving initial 360 degrees cryosurgical treatment required fewer repeat treatments than patients receiving initial 180 degrees treatment (P = 0.004); complications were slightly more common in the 360 degrees group.     

Cyclocryotherapy for glaucoma. Evaluation of techniques

Clinical results of cyclocryotherapy reported by various authors have been contradictory. This is partly due to considerable differences in technique. In this paper, details of the technique of cyclocryotherapy are reviewed in order to determine the most effective protocol of treatment. Parameters such as temperature, duration, probe placement, diameter of the tip, pressure exerted on sclera, extent of ciliary body freezing, additional cyclocryotherapy and preparation of patient for treatment are discussed.
