目的探讨暗室低头试验在早期诊断原发性闭角型青光眼中的作用。方法将可疑原发性闭角型青光眼患者行暗室低头60min试验,测量试验前后眼压并作房角检查,试验阳性者进行了激光虹膜切开术治疗,并随访1～5月后,再复查本试验。结果可疑原发性闭角型青光眼35例70只眼中试验呈阳性为57只眼,阴性为13只眼,阳性患者中有10例20只眼接受了激光虹膜切开术治疗后复查本试验转为阴性。结论暗室低头试验能提供原发性闭角型青光眼早期的诊断依据,以避免急性发作,可对激光虹膜切开术治疗后提供治疗效果及明确分型。
Objective To investigate the role of dark bowel test in the early diagnosis of primary angle-closure glaucoma. Methods The patients with suspected primary angle-closure glaucoma underwent dark bowel test for 60 minutes. The intraocular pressure (IOP) before and after the test was measured and the angle was examined. The patients with positive IOL were treated with laser iridectomy and were followed up for 1-5 months This test. Results Susceptibility of primary angle-closure glaucoma in 35 eyes 70 eyes were positive in 57 eyes, the negative was 13 eyes, positive in 10 patients 20 eyes underwent laser iridectomy after the review of the test turn Negative. Conclusions The dark bowel test can provide the basis for the early diagnosis of primary angle-closure glaucoma to avoid acute attack and provide therapeutic effect and clear typing after laser iridectomy.
