摘要：背景在诊所之外的场所使用血压测量仪器自测血压,也能检测出高血压并进行治疗。目前在英国,全科诊所候诊室是能进行自测血压的主要场所。目的调查人们使用或不使用血压自测仪器测量血压的原因。设计与场所本项横断面定性研究在英国牛津郡开展。方法对在全科诊所外科及社区通过张贴广告招募的人员进行半结构式访谈并进行录音、记录及整理。结果 30例受访者中,有20%患有高血压,近乎一半的受访者自测过血压。无高血压史的受访者很少关注血压问题,其在候诊室里自测血压只是为了打发等待就诊的时间或者帮助全科医生测量这一项目。而有高血压史的受访者称,其自测血压是为了避免发生"白大衣综合征"相关的症状,并想更主动地控制血压测量过程。受访者认为自测血压率不高主要是因为缺少自测血压意识,对自己的测量技术没有把握以及不愿意在公众场合测量血压。不过始料未及的是,有几例受访者称其更愿意在候诊室里而不是在家里自测血压。结论自测血压的公众接受程度尚可。今后,需要加强未曾自测过血压的人们自测血压的必要性意识,宣传血压自测仪器的所在处以及使用方法。全科诊所候诊室管理者应为那些不愿意或者不能在家里自测血压的高血压患者提供自测血压服务。

摘要：Objective: The Low- Pressure Glaucoma Treatment study (LoGTs) seeks to evaluate visual field stability in low- pre- ssure glaucoma patients randomized to intraocular pressure reduction in both eyes with topical twice daily brimonidine tartrate 0.2% versus twice daily timolol maleate 0.5% . This article describes the LoGTs design and presents baseline characteristics of the subjects. Design: Randomized, multicenter, double- masked clinical trial. Participants: Low- pressure glaucoma patients 30 years of age or older were identified. Exclusion criteria included an untreated pressure of more than 21 mmHg, advanced visual field loss, and contraindications to study medications. Interventions: Randomization of both eyes to double- masked monotherapy with brimonidine or timolol. Follow- up visits included Humphrey 24- 2 full- threshold perimetry, tonometry every 4 months, and annual optic disc photography. main Outcome measure: Progression of visual field loss. Results: One hundred ninety patients were randomized between 1998 and 2000. mean age (± standard deviation) was 64.9± 10.7 years. Women comprised 59.5% of the patients. Fifty- three patients (27.9% ) had unilateral field loss. The 137 patients with bilateral field loss were older than those with unilateral field loss: 65.7 versus 62.3 years of age (P< 0.05). mean untreated diurnal intraocular pressures were similar between the eyes of the bilateral patients (mean, 15.5 mmHg in both eyes) and unilateral patients (mean, 16.0 mmHg in field loss vs. 15.6 mmHg in fellow eyes). Visual field mean deviation for all eyes was- 5.4± 4.7 decibels. Central corneal thickness in 168 phakic patients was 543± 35 μ m (range,435- 655 μ m); thickness was less than 500 μ m in 15 eyes and was more than 600 μ m in 11 eyes. mean vertical cup- to- disc ratio for all eyes was 0.67± 0.15. Unilateral field loss patients had a larger cupto- disc ratio in the field loss eye (0.75± 0.12) than the fello weye with a normal field (0.60± 0.17, P< 0.0
