Twenty-four eyes of 20 patients with chronic open angle glaucoma who had a trabeculectomy were studied retrospectively. Trabeculectomy resulted in a significant lowering of mean intraocular pressures and improvement of pressure control for the group. Progression of visual field defects occurred in all 24 eyes preoperatively, while postoperatively, the fields of 14 eyes showed no change, but the other ten showed further progression. A comparison of the pressures of the eyes showing continued progression after surgery with the eyes showing no further progression revealed no significant difference in the mean preoperative or postoperative pressure or the mean pressure reduction after surgery. Measurements of the quality of the control, however, showed that the quality of pressure control was significantly better in the eyes that did not show progression of field loss postoperatively. Careful postoperative follow-up observation of the visual field remains necessary even after successful surgical pressure reduction.
对20例接受小梁切除术的慢性开角型青光眼患者的24只眼进行回顾性研究。小梁切除术使该组患者的平均眼压显著降低，眼压控制得到改善。所有24只眼术前均存在视野缺损进展，而术后，14只眼的视野无变化，但另外10只眼出现进一步进展。对术后仍持续进展的眼与未进一步进展的眼的眼压进行比较，结果显示术前平均眼压、术后平均眼压或术后眼压降低幅度均无显著差异。然而，对眼压控制质量的测量表明，术后未出现视野缺损进展的眼的眼压控制质量明显更好。即使手术成功降低眼压后，仍需对视野进行仔细的术后随访观察。
