Laser trabeculoplasty was performed in one eye in each of 38 patients with uncontrolled chronic open-angle glaucoma (37 patients) or low-tension glaucoma (1). Topical therapy was stopped for 1 week before the procedure and for 1 week before reassessment 6 weeks later. Differential light threshold values were determined with an automatic perimeter four times throughout the study, and colour vision was tested twice. The patients were followed for 3 months. The rise and subsequent drop in intraocular pressure were not found to be correlated with differential light threshold or colour error scores.
对38例慢性开角型青光眼（37例）或低眼压性青光眼（1例）患者的单眼进行了激光小梁成形术。术前1周及6周后重新评估前1周停用局部治疗。在整个研究过程中，使用自动视野计四次测定微分光阈值，并两次测试色觉。对患者进行了3个月的随访。未发现眼压的升高及随后的下降与微分光阈值或色觉误差评分相关。
