PURPOSE
To investigate the effect of trabeculectomy on the intraocular pressure (IOP) fluctuations caused by the postural change in patients with open-angle glaucoma.
METHODS
Prospective, nonrandomized study. Ten eyes of 10 patients with primary open-angle glaucoma and 3 eyes of 3 patients with normal-tension glaucoma who underwent trabeculectomy were studied. The IOP at the baseline and 3 months after trabeculectomy was measured in both sitting and supine positions. A pneumatonometer was used to measure the IOP in both sitting and supine position.
RESULTS
The mean IOP in the sitting position was 19.6+/-5.1 mm Hg at the baseline and 9.4+/-2.9 mm Hg after trabeculectomy (P<0.01, paired t test). The mean difference in IOP between the sitting and supine position was 4.1+/-1.6 mm Hg at the baseline and 2.2+/-1.5 mm Hg after trabeculectomy (P=0.01, paired t test).
CONCLUSIONS
Trabeculectomy might decrease not only the IOP in the sitting position but also the magnitude of IOP elevation associated with the postural change.
目的
研究小梁切除术对开角型青光眼患者体位变化引起的眼压波动的影响。
方法
前瞻性、非随机研究。10 例原发性开角型青光眼患者和 3 例正常眼压性青光眼患者共 13 眼接受小梁切除术。分别于术前和术后 3 个月测量患者在坐位和仰卧位时的眼压。使用眼压计测量患者在坐位和仰卧位时的眼压。
结果
术前，患者坐位时的平均眼压为 19.6+/-5.1mmHg，术后为 9.4+/-2.9mmHg（P<0.01，配对 t 检验）。术前，患者坐位与仰卧位时的眼压差值为 4.1+/-1.6mmHg，术后为 2.2+/-1.5mmHg（P=0.01，配对 t 检验）。
结论
小梁切除术不仅能降低患者坐位时的眼压，还能降低与体位变化相关的眼压升高幅度。
