The change in intraocular pressure achieved after 98 trabeculectomy operations performed on 70 patients with primary open-angle glaucoma was analysed. The reduction was proportional to the untreated preoperative pressure, and the results indicated that a first trabeculectomy reduced the intraocular pressure to between 16 and 20 mmHg irrespective of its initial level. Cases which required medical therapy for final pressure control after surgery showed a distribution of initial intraocular pressure similar to those not requiring such therapy. In addition, these cases were reduced to a level of pressure only slightly above the arbitrary figure of 20 mmHg before medical therapy was added, and were therefore considered almost to have reached the normal physiological range. Cases submitted to a second trabeculectomy are discussed, including 2 cases with unexplained acute open-angle glaucoma some months after the first operation.
对70例原发性开角型青光眼患者进行的98次小梁切除术术后眼压变化进行了分析。眼压降低与术前未治疗的眼压成比例，结果表明，首次小梁切除术可将眼压降至16至20 mmHg之间，而不论其初始水平如何。术后需要药物治疗以控制最终眼压的病例，其初始眼压分布与不需要此类治疗的病例相似。此外，这些病例在添加药物治疗之前，眼压仅降至略高于任意设定的20 mmHg的水平，因此被认为几乎已达到正常生理范围。文中讨论了接受二次小梁切除术的病例，包括2例在首次手术后数月出现不明原因急性开角型青光眼的病例。
